It still persists also on Winxp + PHP5.4.4 Previous Comments: ------------------------------------------------------------------------ [2011-03-05 16:16:31] stano110 at azet dot sk thanks for explanation. I have the same problem, cannot remove plugin directory with the font locked. It's a pity, that this problem still persists also on Win7+PHP5.3.3. ------------------------------------------------------------------------ [2003-07-14 18:24:43] pajoye@php.net Hello, We cannot fix it. Freetype keeps the file handle open and windows interprets that as a lock. Test your script on a unix system and it should work like a charm. thanks for your report, pierre ------------------------------------------------------------------------ [2003-07-03 18:44:10] choinet at rocketmail dot com I don't necessarily want to delete the file, but I want to be able to hypothetically delete the parent directory above it :) I'm developing an image management system that also allows for random image generation with text, and perhaps I would need to remove a parent directory or the file itself. ------------------------------------------------------------------------ [2003-07-01 18:37:04] sniper@php.net Just curious..but why do you want to delete the file? :) ------------------------------------------------------------------------ [2003-07-01 17:45:37] choinet at rocketmail dot com Description: ------------ My computer setup is Apache 2.0.46,PHP 4.3.2, and Windows XP SP1. Only modifications to php.ini are: 'extension=php_gd2.dll' and 'log_errors' are enabled. Originally, I was trying to use the imagettftext() function to write text to a png file. I used the function in a similar context as described by the manual, and the text write was successful. However, I stumbled upon the discovery that the font file that the function uses was locked by either the webserver or PHP process, as I was not able to unlink or remove the font file. I tried to isolate the problem by testing the code on Windows XP with Apache 1.3.27, Apache 2.0.46, and IIS 5.1 and either PHP 4.2.3, 4.3.2, 4.3.3RC1, or 5.0, so I am thinking that it has something to do with the operating system. Furthermore, this problem does not occur with a webserver running Apache/PHP 4.3.2 on Linux. Also, this problem applies to various true-type font files. The problem only goes away after I stop or restart the webserver. In summary, there are four functions that use a font file that lock it: imagettftext(), imagettfbbox(), imagefttext(), and imageftbbox(). Reproduce code: --------------- $im = imagecreatefrompng('test.png'); $blue = imagecolorallocate($im, 0, 102, 255); $font = 'tahoma.ttf'; // // These four functions lock the font file and do not release it // imagettftext($im, 10, 0, 10, 25, $blue, $font, 'text'); imagettfbbox (20, 0, $font, 'text'); imagefttext ($im, 12, 0, 10, 20, 5, $font, 'text', $foo); imageftbbox (12, 0, $font, 'text', $foo); header('Content-Type: image/png'); imagepng($im); imagedestroy($im); unlink($font); Expected result: ---------------- I expect to see the png image generated and the font file unlinked. Actual result: -------------- The image displays fine but the font file cannot be deleted. (Windows Error Dialog Box after manually attempting to delete arial.ttf) Cannot delete arial: It is being used by another person or program. Close any programs that might be using the file and try again.
