Description:
------------
All of the TTF files that are on PHP.net appear to be invalid/corrupt.

A change that happened 12 months ago with the description of "Fix TTF files" appears to be where the problem lies.

http://svn.php.net/viewvc?view=revision&revision=284292

To fix this, this revision should be reverted to all files.

On Windows, when you try to open any of these files it will say

"The requested file *.ttf was not a valid font file".

Here at PHP, we get a different message when using the imagettfbbox() function...

"Could not read font".

In the example below I am using the arial.ttf file which can be downloaded here:
http://svn.php.net/viewvc/web/php/trunk/bin/arial.ttf?view=co

Test script:
---------------
<?php

$font = 'fonts/arial.ttf';

$read = file_exists($font)?'Yes':'No';
echo "\n<br>Does font '$font' exist? ".$read;

$read = is_readable($font)?'Yes':'No';
echo "\n<br>Is font '$font' readable? ".$read;

$test = @imagettfbbox(1, 1, $font, 1)?'Yes':'No';
echo "\n<br>Is font '$font' valid? ".$test;

echo "\n<br>What PHP version? ".phpversion();

?>

Expected result:
----------------
Does font 'fonts/arial.ttf' exist? Yes
Is font 'fonts/arial.ttf' readable? Yes
Is font 'fonts/arial.ttf' valid? Yes
What PHP version? 5.2.13

Actual result:
--------------
Does font 'fonts/arial.ttf' exist? Yes
Is font 'fonts/arial.ttf' readable? Yes
Is font 'fonts/arial.ttf' valid? No
What PHP version? 5.2.13

Confirmed on Windows XP aswell (unreadable font files in the font viewer)

Rasmus: You did this change, should it be reverted or do you have any easy fix on your mind?
 [2010-07-27 01:54 UTC] rasmus@php.net
You may just have to re-import them into Subversion or something.  All I did was 
flip the svn property so Subversion wouldn't mangle them.

I would if I could.

I don't think I have commit access to all of the ttf files on the php.net svn.

This is not a difficult bug to fix. Anybody with commit access should be able to fix it.

Can somebody fix it?

Thanks.

This... doesn't seem to be just those .ttf files. I grabbed 
http://ftp.gnome.org/pub/GNOME/sources/ttf-bitstream-vera/1.10/ and there's no 
differences against http://github.com/pear/Image_Text/tests/

Trying to open these; I get:
 imagettfbbox(): Could not read font

Comment:
------------
I was unable to replicate clockwerx's findings.

According to my results there is only a problem with the fonts changed by rasmus 
in r284292.

New test script:
------------
<?php

$fonts=array();

//from https://github.com/pear/Image_Text/raw/master/tests/Vera.ttf
$fonts[]='fonts/Vera.ttf';

//from http://ftp.gnome.org/pub/GNOME/sources/ttf-bitstream-vera/1.10/ttf-
bitstream-vera-1.10.zip
$fonts[] = 'fonts/ttf-bitstream-vera-1.10/Vera.ttf';

foreach ($fonts as $font) {
    $read = file_exists($font)?'Yes':'No';
    echo "Does font '$font' exist? $read\n<br>";

    $read = is_readable($font)?'Yes':'No';
    echo "Is font '$font' readable? $read\n<br>";

    $test = @imagettfbbox(1, 1, $font, 1)?'Yes':'No';
    echo "Is font '$font' valid? $test\n<br>";

    echo "What PHP version? ".phpversion()."\n<br>";

    echo "\n<br>";
}
?>

Results:
------------
Here's the results of that:

Does font 'fonts/Vera.ttf' exist? Yes 
Is font 'fonts/Vera.ttf' readable? Yes 
Is font 'fonts/Vera.ttf' valid? No 
What PHP version? 5.3.4 

Does font 'fonts/ttf-bitstream-vera-1.10/Vera.ttf' exist? Yes 
Is font 'fonts/ttf-bitstream-vera-1.10/Vera.ttf' readable? Yes 
Is font 'fonts/ttf-bitstream-vera-1.10/Vera.ttf' valid? Yes 
What PHP version? 5.3.4

Conclusion:
------------
In r284292 rasmus made a change which changed the EOL of these font files. These 
files use a "Mixed" EOL while the original files use just Unix type EOL.

Solution:
------------
Roll back r284292.

Why are you downloading these fonts from our servers?

Do we link to them somewhere for something?

I recently removed them from phpweb as I couldn't see them used with anything.
