I have a PHP website was build by using Codeigniter framework. I always got the following error message form Apache log:

PHP Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 8192 bytes) in /usr/local/apache2/htdocs/mywebsite/application/helpers/my_helper.php on line 150

About my_helper.php on line 150 is the following:

function objectToArray( $object ){
if( !is_object( $object ) && !is_array( $object ) )
    {           
        return $object;
    }
    if( is_object( $object ) )
    {
        $object = get_object_vars( $object );   # <<<<<<< Line 150
    }   
    return array_map( 'objectToArray', $object );  
}

The function of "objectToArray" is using to process XPATH result object form XML file(I use simplexml_load_file to load the XML file).

# The example to pass XML object by following: #

$xmlObject = simplexml_load_file(PATH_TO_XML_FILE, 'SimpleXMLElement', LIBXML_NOCDATA);
$data = $xmlObject->xpath(MY_XPATH);
$ary = objectToArray($data);

Also I tried to set the memory_limit value to unlimit(ini_set('memory_limit',-1)), but it still have the error.

Is there have any tuning about hardware or programing to prevent the problem? Thanks!

  • I had a similar issue once and realised it was just me being stupid - If I remember correctly I was trying to load a model within the same model and it resulted in a similar error message. Just check that you aren't creating a 'resource loop' - may help! – tommyd456 Feb 08 '13 at 14:37
