ereg
is deprecated. Don't use it.preg
functions are all "Perl regular expressions" meaning you need to have some sort of beginning and end marker on your regex. Often this will be /
or #
, but any non alpha-numeric will do fine.For example, these will work:
preg_match("/foo/u",$needle,$haystack);
preg_match("#foo#i",$needle,$haystack);
preg_match("@foo@",$needle,$haystack);
preg_match("\$foo\$w",$needle,$haystack); // bad idea because `$` means something
// in regex but it is valid anyway
// also, they need to be escaped since
// I'm using " instead of '
But this will not:
preg_match("foo",$needle,$haystack); // no delimiter!
