imagecreatetruecolor（）在symfony中不起作用，但如果作为php脚本运行则可以正常工作

The class which contains the method is as follows:

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;
      }
   }
?>

The following code is added in symfony as well as the local script. It works fine in the local script but fails in symfony:

symfony中添加了以下代码以及本地脚本。它在本地脚本中工作正常但在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';

The method is called thus:

因此调用该方法:

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

You probably have two versions of PHP installed:

您可能安装了两个版本的PHP:

the Apache extension used when running it via Symfony

通过Symfony运行它时使用的Apache扩展

and the PHP cli used when you run scripts

以及运行脚本时使用的PHP cli

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.

每个版本都有自己的php.ini配置文件。您可能没有加载扩展或在Apache配置文件中错误配置它。

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

执行phpinfo()时,您可以找到Apache php.ini配置文件的位置。 (例如在Symfony工具栏中)
