Php Question Mark Before Type

[Lynne Pruskowski]

Typedeclarations for parameters and return values can now be marked as nullable by prefixing the type name with a question mark. This signifies that as well as the specified type, NULL can be passed as an argument, or returned as a value, respectively.

In written English (mainly online) I often come across sentences ending with a question or an exclamation mark with a space before it. Is it always just an error or a typo? Or there are cases when it is a correct English, for example after closing parentheses or some other punctuation marks?

In English, it is always an error. There should be no space between a sentence and its ending punctuation, whether that's a period, a question mark, or an exclamation mark. There should also be no space before a colon, semicolon, or comma. The only ending punctuation mark that sometimes needs to be preceded by a space is a dash.

People have mentioned in the comments that, yes, in the past, a small (non-breaking) space was inserted before an ! and a ? These must never start a new line. The space is also a small space, very clearly much more than the space between letters of a word, but much less than a sentence-ending space.

13.52 Ellipses with other punctuation. Placement of the other punctuation depends on whether the omission precedes or follows the mark; when the omission precedes it, a nonbreakable space should be used between the ellipsis and the mark of punctuation to prevent the mark from continuing over to the beginning of a new line.

There is so much to love about fudge ... . [I feel the ellipsis before a period is the weakest example because it's arguable whether the ellipsis should come before or after the period, if at all.]

Stack Exchange's parser is pretty good (because of how you use Markup) but on many other sites, especially where the text editor automatically linkifies for you put a space in can be the difference between your link working or not.

In many cases, it is essential for readability to put a space before an exclamation mark! Not there but here's an example: lol ! Due to the font, the space is in fact not needed there, but many fonts leave an L looking too much like an ! to be readable.

The best, perhaps only, reason for one space between end of sentence and its punctuation is for the !, following upright fonts resembling too closely the ! itself. Only other occurrence would be typographical error. Readability trumps convention.

Written language convention mutates. Consider Webster. Allow brief, supporting narrative: I'm a journalist and an English teacher who now abides my students using ONE space between manuscript sentences--not the conventional, PROPER, two. I don't expect generations born into texting, IMs, emails, all things digital, to embrace tradition. With discussion and exposure, on-line users might accept an intentional, rare space before the !. Now, I'll go read "tips on writing great answers." No, we don't always read manuals before assembly . . . .

I m new to Crystal Reports and I have a question regarding parameters. Someone at work created a Crystal Report and it contains 2 parameters that have an icon which is new to me when it comes to parameter. The icon looks like a question mark along with a Database icon.

When you open the Formula Workshop the parameters show up under the 'Report Fields'. Yes, then contain a '?' mark before their name. When you double-click the parameter in the formula workshop to use it in the report, the parameter will look like this:

Once you locate the parameter, right-click it and select 'Edit'. It will show you if the parameter is 'Static' or 'Dynamic'. It will also show the database field being used(if at all) as the 'List-of-values' and some more options.

Under Parameter Fields, I have three Parameters. One parameter has a regular icon, but the other 2 have an icon that has a question mark and a database cylinder as its icon. I was wondering why is it that these two parameters have different icons.

I'm editing an InDesign document created by someone else, and I'm unable to type certain characters, including ? @ # $ % ^. When I type a question mark (or any of the others), nothing happens. Other standard keyboard punctuation marks and special characters work fine.

Edit - In paragraph 1, when I said "nothing happens," I was referring to Notes mode, where I originally discovered the issue. In paragraph 2, I realized that in regular text mode, some of those characters appear to be undocumented keyboard shortcuts (at least in this document).

Let's start by checking your Paragraph Styles panel. Are there Shift + numbers assigned as shortcuts? How about Shift+/? These are user-assigned, so you will not find them in the shortcut list. (Actually, check all of the styles panels: all can be assigned these keyboard shortcuts.)

I'm using US English, Mac OS 11.7.1. I have no trouble with question marks in any other application. The question marks in my original post was typed the usual way. It's been several years since I've used InDesign (I think the last time was 2020), and I don't remember having that trouble before. However, the documents I worked on back then may not have had any question marks.

My apologies for bringing this up but I am having the same issue as @Automate2create. The filter does work before saving to the collection. I can filter the data from the Dataverse no problem. PowerApps can see the choice columns from the dataverse. But when you copy the table from the dataverse into collection then you get the "?" value mostly for choices, owner, and some ID columns. My workaround for a small table without any lookup column is to filter by those data and use the AddColumn and RenameColumn.

I have a table of Electricians as an example. Of course I prefer a big table with all departments. I can merge them all into one table but for now I am using Electrical table.

Does anybody know why the choice columns showing "?" value after saving from Dataverse to the collection?

This just happened to me but I am using choice columns. So I have other collections where I am using choice columns and they are ok. But I have created a new collection and when I look at the data from the collection, anything that is a choice column is showing question marks. I've never seen this until today. Why would it be?

In the fifth century, Syriac Bible manuscripts used question markers, according to a 2011 theory by manuscript specialist Chip Coakley: he believes the zagwa elaya ("upper pair"), a vertical double dot over a word at the start of a sentence, indicates that the sentence is a question.[2][3]

From the 10th century, the pitch-defining element (if it ever existed) seems to have been gradually forgotten, so that the "lightning flash" sign (with the stroke sometimes slightly curved) is often seen indifferently at the end of clauses, whether they embody a question or not.[citation needed]

In the early 13th century, when the growth of communities of scholars (universities) in Paris and other major cities led to an expansion and streamlining of the book-production trade,[8] punctuation was rationalized by assigning the "lightning flash" specifically to interrogatives; by this time the stroke was more sharply curved and can easily be recognized as the modern question mark. (See, for example, De Aetna [it] (1496) printed by Aldo Manuzio in Venice.[9])

The mark which you are to notice in this lesson is of this shape ? You see it is made by placing a little crooked mark over a period.... The name of this mark is the Question Mark, because it is always put after a question. Sometimes it is called by a longer and harder name. The long and hard name is the Interrogation Point.

In English, the question mark typically occurs at the end of a sentence, where it replaces the full stop (period). However, the question mark may also occur at the end of a clause or phrase, where it replaces the comma .mw-parser-output div.crossreferencepadding-left:0(see also Question comma):

In Spanish, since the second edition of the Ortografa of the Real Academia Espaola in 1754, interrogatives require both opening and closing ? question marks.[13][14] An interrogative sentence, clause, or phrase begins with an inverted question mark and ends with the question mark ?, as in:

Galician also uses the inverted opening question mark, though usually only in long sentences or in cases that would otherwise be ambiguous. Basque and Catalan, however, use only the terminal question mark.[clarification needed]

The Greek question mark (Greek: ερωτηματικό, romanized: erōtīmatik) looks like ;. It appeared around the same time as the Latin one, in the 8th century.[18] It was adopted by Church Slavonic and eventually settled on a form essentially similar to the Latin semicolon. In Unicode, it is separately encoded as U+037E GREEK QUESTION MARK, but the similarity is so great that the code point is normalised to U+003B ; SEMICOLON, making the marks identical in practice.[19] In Greek, the question mark is used even for indirect questions.

The Arabic question mark is also used in some other right-to-left scripts: N'Ko, Syriac and Adlam.Adlam also has U+1E95F ? ADLAM INITIAL QUESTION MARK: ? ???? , 'No?'.[20][better source needed]

The question mark can also be used as a meta-sign to signal uncertainty regarding what precedes it. It is usually put between brackets: (?). The uncertainty may concern either a superficial level (such as unsure spelling), or a deeper truth (real meaning).

The inverted question mark () corresponds to Unicode code-point U+00BF INVERTED QUESTION MARK (¿), and can be accessed from the keyboard in Microsoft Windows on the default US layout by holding down the Alt and typing either 1 6 8 (ANSI) or 0 1 9 1 (Unicode) on the numeric keypad. In GNOME applications on Linux operating systems, it can be entered by typing the hexadecimal Unicode character (minus leading zeros) while holding down both Ctrl and Shift, I J mm.e.: Ctrl Shift B F. In recent XFree86 and X.Org incarnations of the X Window System, it can be accessed as a compose sequence of two straight question marks, i.e. pressing Compose ? ? yields . In classic Mac OS and Mac OS X (macOS), the key combination Option Shift ? produces an inverted question mark.
