PHP 7 Compatability?

[TracerRx]

Has anyone tested against PHP 7 yet?

I get: 

JpGraph Error: 13 The installed PHP version (7.0.0RC5) is not compatible with this release of the library. The library requires at least PHP version 5.1.0

[Frank Reichel]

If you are using version 3.0.7: Locate the file jpgraph.php on your server and load the file in your editor.

Change line 232 from:

    if ($majorC != $majorR) return false;

To:

    if ($majorC > $majorR) return true;

and go!

Disclaimer: Just a quick and dirty hack...

The dirty hack does do the job, but gives me the following notification:

PHP Deprecated:  Methods with the same name as their class will not be constructors in a future version of PHP; LinePlot has a deprecated constructor in /jpgraph/jpgraph_line.php on line 24
PHP Deprecated:  Methods with the same name as their class will not be constructors in a future version of PHP; GroupBarPlot has a deprecated constructor in /jpgraph/jpgraph_bar.php on line 627

I suppose the notification is likewise using other plots.

Will Asial Corporation ever publish an update of jpgaph that flawlessly supports PHP7 and up ?

[Chris Savchick]

I asked about support and updates recently, as I am about to recommend purchase for commercial use. I received the below response via email on Feb 3, 2016...

Hi San Francisco,

I'm also interested in the latest version of JPGRAPH library for PHP.
We are currently using PHP 5.x with JPGRAPH version 2.1.3 on a 32 bits windows.
As I am currently upgrading to PHP 7 x64, the constructors won't make it...
My first idea was trying changing all constructors names using  __constructor().
However, might some other deprecated methods are in the numerous files of the library, this won't be worth to start this way.

Do you have a release date for the PHP7 compatible version ?
In between, what would be the best workaround ?
Also, does the latest version  has retro compatibility with v2.1.3 ? will I need to change my PHP code ?

Thanks;

[Toma mutemi]

dirty hack but worked for me thanks

I use the latest version on Php 7.1.3, everything is working like a charm.

hi claude,

are you not experiencing issues with jpgraph 4.2.0 specifically in font files?

[Claude Deslandes]

Good day Ralf,

     No problems with the font files.   I have this directory structure : root://jpgraph/src/fonts and all of my jpgraph are called directly from the jpgraph/src   

     Take a look at your jpg-config.inc.php to see if you would not have to set the value of your TTF_DIR or others.

     Claude :-)

[Jay Rizzi]

claude, do you have the examples loaded on your servr? if so can you check  barformatcallbackex1.php?

my install is working but not putting values at the tops of the bars like previous versions have, just want confirmation if pro is working versus regular

[Claude Deslandes]

Hello Jay,

   Sorry about the delay... yes, the barformatcallbackex1.php works great with PHP 7.x

Claude :-)

[Ralf Laxina]

thanks for the response claude.. i'm currently using jpgraph 4.2.0 in php 7.2.0

still having trouble making them work together though hehe..

[Claude Deslandes]

Hello Ralf,

     I am using Jpgraph-4.1.1-pro, I will try to run the graph under 4.2.

     Claude :-)

[Ralf Laxina]

hello claude,

i got another error in jpg, i think this is compatibility issue on php 7. please see below

Warning: count(): Parameter must be an array or an object that implements Countable ... src\jpgraph.php on line 1300

I wanna how how the following code is being use. this is where the warning error is pointing.

        $n = count($this->iTables);

        for( $i=0; $i < $n; ++$i ) {

            $csim .= $this->iTables[$i]->GetCSIMareas();

        }

Thanks in advance!
