RE: [PHP-DB] preg_math vs preg_match_all

For those perl fans out there, preg_match_all adds the g (global) flag =
to the expression. So this:

preg_match('/foo/', $str, $match);

would be like

$str =3D~ /foo/;

preg_match_all('/foo/', $str, $match);

like

$str =3D~ /foo/g;

p.s. - anyone coming from Perl to PHP can get a little hung up on the =
preg_* functions...

preg_match stops after the first match.
preg_match_all gets *all* the matches.

E.g.  If you have a string -> $str =3D "foofoo";
preg_match('/foo/', $str, $match); -> $match will have an array with one =

"foo".
preg_match_all('/foo/', $str, $match); -> $match will have an array with =

two "foo".

Thats basically it.
