PHP pcre Regular Expression max characters? -- regex, preg_match
seanhess asked on
PHP's preg_match seems to be failing when the subject has too many characters in it.
This is my expression::
preg_match('/(.*<div id="storeArea">\s*)(.*)(\s
And here is the subject
<html>
<body>
<div id="storeArea">
<div>aaa ... </div>
<div>aaa ... </div>
<div>aaa ... </div>
</div>
<!--POST-BODY-START-->
<!--POST-BODY-END-->
</body>
</html>
It will match fine on that, but if the aaa .... is made HUGELY long, it won't match any more. I tested it with 80,000 a's in each line. If there was only one line (div tag) of A's, it would match, but it wouldn't match 3 lines of a's.
Is there a character limit to preg_match? Why would it behave like this? Can I fix the regular expression?
Thanks!
We're sending info to a php script. It is supposed to match a regular expression against the data.
