Purpose of backlslash in the following code?

[Cecil Champenois]

echo "<div id=\"invoices\">";

 

Just what exactly is the purpose of the backslash, which is preceding the string, "invoices\" ? Is this some kind of escape thing? I see it all over the PHP code I see on the Internet, but no explanation. It is as if its purpose is a national secret.

To `escape` the quotes. So that way php prints the " and doesn't treat it as if its outside the text to be printed/echo'd

SHHHHHHHHHH.

It's a national secret :(

The NSA's got your home wire tapped, now.

If you're looking at the code I sent earlier, it's a horrible,
horrible example of code.

No, definitely not a secret, but definitely timely to the recent discussions...

the ' \ ' is simply there to tell the PHP parser to treat the " as a character and render it as-is.  An alternative would be to do this:  echo '<div id="invoices">';  that is, if this wasn't 2010 and echoing out HTML markup was still acceptable...

It may be a global secret.

Okie dokie, this is making sense, incredibly:

 

When I first looked at the below code, I only glanced at it and didn't see the <?php tag, which preceded it. Since the code is going through PHP interpretation first, then it makes sense.

 

The code originated from: http://pastebin.com/FP6L8Mdz

 

1. <?php
2. echo "<div id=\"invoices\">";
3.         echo "<div class=\"report_nav\">";
4.                 echo "<a target=\"_blank\" href=\"/invoices/charge_report_print/{$report_date}\">Print Report</a>";
5.         echo "</div>";
6.         echo "<h1>Daily Charge Report</h1>";
7.         echo "<div style=\"text-align: center\">";
8.                 echo "<h1>";
