The constant XML_PARSE_HUGE
can be passed as the third argument to simplexml_load_string()
. According to to php.net this flag:
relaxes any hardcoded limit from the parser.
What is the "default hardcoded limit from the parser"?
I think relaxes is a little bit ambiguous also. Does it eliminate or increase "the hardcoded limit"?
From http://bugs.php.net/49660:
Since version 2.7.3 libxml limits the maximum size of a single text node to 10MB. The limit can be removed with a new option, XML_PARSE_HUGE. PHP has no way to specify this option to libxml.
So I imagine this flag is the way that PHP now has to specify this option.
time has moved: http://php.net/manual/en/libxml.constants.php
LIBXML_PARSEHUGE - Sets XML_PARSE_HUGE flag, which relaxes any hardcoded limit from the parser. This affects limits like maximum depth of a document or the entity recursion, as well as limits of the size of text nodes.
Only available in Libxml >= 2.7.0 (as of PHP >= *5.3.2 and PHP >= 5.2.12)*
//example of use
$xmlDoc = new DOMDocument();
$xmlDoc->loadXML( $xml , LIBXML_PARSEHUGE );
