【PHP】symfony Warning:&nbs…

If you are installing a symfony 1.x project on a PHP 5.4.1 (or
later) version, you may encounter this warning message :

Warning: ob_start(): function ” not found or invalid function name
in /var/www/lib/config/sfApplicationConfiguration.class.php on line
157 Notice: ob_start(): failed to create buffer in
/var/www/lib/config/sfApplicationConfiguration.class.php on line
157

To fix it, go on your
/lib/config/sfApplicationConfiguration.class.php file and change
this

// compress output

if (! self::$coreLoaded) {

ob_start ( sfConfig::get ( 'sf_compressed' ) ?
'ob_gzhandler' : '' );

}

to this

// compress output

if (! self::$coreLoaded) {

ob_start ( sfConfig::get ( 'sf_compressed' )
? 'ob_gzhandler' : null );

}

以上解决了在symfony 1.X版本下，升级了php至5.4.x以上的时候会报错的问题。
