function drupal_check_memory_limit
drupal_check_memory_limit($required, $memory_limit = NULL)
Compares the memory required for an operation to the available memory.
Parameters
$required: The memory required for the operation, expressed as a number of bytes with optional SI or IEC binary unit prefix (e.g. 2, 3K, 5MB, 10G, 6GiB, 8bytes, 9mbytes).
$memory_limit: (optional) The memory limit for the operation, expressed as a number of bytes with optional SI or IEC binary unit prefix (e.g. 2, 3K, 5MB, 10G, 6GiB, 8bytes, 9mbytes). If no value is passed, the current PHP memory_limit will be used. Defaults to NULL.
Return value
TRUE if there is sufficient memory to allow the operation, or FALSE otherwise.

Code
function drupal_check_memory_limit($required, $memory_limit = NULL) { if (!isset($memory_limit)) { $memory_limit = ini_get('memory_limit'); } // There is sufficient memory if: // - No memory limit is set. // - The memory limit is set to unlimited (-1). // - The memory limit is greater than the memory required for the operation. return ((!$memory_limit) || ($memory_limit == -1) || (parse_size($memory_limit) >= parse_size($required))); }
