包含该方法的类如下：

<?php
   class renderText {
      function text_to_image( $text, $width, $height, $image_file ) {
         $fonts_dir = 'path/to/directory/in/which/SreeKrushnadevaraya.ttf/is/located/';
         $ret = mb_language('uni');
         mb_internal_encoding('UTF-8');
         header('Content-type: image/gif');
         $font = $fonts_dir.'SreeKrushnadevaraya.ttf';
         error_log("=before imagecrttrucolour",3,'path/to/frontend_dev.log');
         $im = imagecreatetruecolor( $width, $height );
         error_log("=after imagecrttrucolour",3,'path/to/frontend_dev.log');
         $white = imagecolorallocate( $im, 255, 255, 255 );
         $black = imagecolorallocate( $im, 0, 0, 0 );
         imagefilledrectangle( $im, 0, 0, $width, $height, $white );
         imagettftext( $im, 10, 0,10 ,30, $black, $font, $text );
         $image_file = '/tmp/'.date('YmdHis').$width.$height.'.gif';
         imagegif( $im, $image_file );
         imagedestroy( $im );
         return $image_file;
      }
   }
?>

以下代码添加到 symfony 以及本地脚本中。它在本地脚本中运行良好，但在 symfony 中失败：

// Set the enviroment variable for GD
putenv('GDFONTPATH=' . realpath('path/to/directory/in/which/SreeKrushnadevaraya.ttf/is/located/'));

// Name the font to be used (note the lack of the .ttf extension)
$font = 'SreeKrushnadevaraya';

该方法是这样调用的：

$image_file = '/tmp/'.date('YmdHis').'260'.'x'.'32.gif';
 $rendered_text = renderText::text_to_image($this->getRequestParameter('caption_unicode'), 240, 32, $image_file);

php 版本：PHP 5.3.6

symfony 版本 1.0.22

You probably have two versions of PHP installed:

  • the Apache extension used when running it via Symfony
  • and the PHP cli used when you run scripts

And each version has it's own php.ini configuration file. You probably haven't loaded the extension or misconfigured it in the Apache configuration file.

You can find out the location of the Apache php.ini configuration file when executing phpinfo(). (In the Symfony toolbar for example)
