Regex with dates.

[kernelgpf]

I have this strip of regex that matches: MM/DD/YYYY and I just need to make it require spaces before each slash (/), as in: MM / DD / YYYY.

 

I've tried "\\s", "\s", "[ ]", "\ " and maybe a few more, new to regex.

 

(0?[1-9]|1[012])[- /.](0?[1-9]|[12][0-9]|3[01])[- /.](19|20)[0-9][0-9]

 

TIA!

(0?[1-9]|1[012]) [-/.] (0?[1-9]|[12][0-9]|3[01]) [-/.] (19|20)[0-9][0-9]

Using "\s" seems to works for me; I just added it before and after the "[-/.]" parts:

 

if(preg_match("~^(0?[1-9]|1[012])\s[- /.]\s(0?[1-9]|[12][0-9]|3[01])\s[- /.]\s(19|20)[0-9][0-9]$~", $_GET['date'])) {
echo 'match';
} else {
echo 'no match';
}

Neither of those work for me, possibly because the dates I am searching for are in a large text blob, it's not just verifying an entire string is a date.

 

if (preg_match_all('~(0?[1-9]|1[012])\s[- /.]\s(0?[1-9]|[12][0-9]|3[01])\s[- /.]\s(19|20)[0-9][0-9]~', $contents, $out, PREG_SET_ORDER)) {
	echo "found a date<p>";
	foreach($out as $val){
		if(empty($val[0])) continue;
	print "found: $val[0]<br>";
	}
}

Figured it out, in the source code it showed tons of spacing and newlines which was throwing it off.
