[php-src] Issue #10344: imagettfbbox(): Could not find/open font UNC path

Issue: https://github.com/php/php-src/issues/10344 Author: JamesHeinrich ### Description imagettfbbox (possibly other TTF-related functions, I haven't tested) does not accept a UNC path to font file in PHP 8.2 on Windows 11. Code works as expected with local filename. Code worked fine with UNC path in PHP 7.4.1. UNC path/filename is accessible to user that Apache/PHP is running under (as shown in sample code). The following code: ```php <?php $font = '\\\\HOSTNAME\\path\\to\\arial.ttf'; // this file exists here, is readable to user PHP runs as //$font = 'C:\\path\\to\\arial.ttf'; // this works //$font = './arial.ttf'; // this works too, since font is in same folder as .php file echo 'file_exists($font)='.(file_exists($font) ? 'TRUE' : 'FALSE').'<br>'; echo 'is_readable($font)='.(is_readable($font) ? 'TRUE' : 'FALSE').'<br>'; echo 'is_file($font)=' .(is_file($font) ? 'TRUE' : 'FALSE').'<br>'; imagettfbbox(10, 0, $font, 'hello'); ``` Resulted in this output: ``` file_exists($font)=TRUE is_readable($font)=TRUE is_file($font)=TRUE E_WARNING: imagettfbbox(): Could not find/open font ``` But I expected this output instead: ``` file_exists($font)=TRUE is_readable($font)=TRUE is_file($font)=TRUE // and no error message ``` ### PHP Version PHP 8.2.0 ### Operating System Windows 11 Pro x64
