Hallo,

this text:




Über <a href="[linkto:13]">allen</a> strahlt die <a
href="[linkto:14]">Sonne</a> – <a href="[linkto:13]">über</a> allen in
der Welt.

preg_match_all( '/\[linkto:(.*)\]/',$text,$linkto );
$num = count($linkto['1']);
echo $num;


Why i get only 1 and not 3 results?

You should have examined the match that was found, and then you would
have seen: that '.*' is greedy. This means that the first 'linkto:' is
found and the the regular expression machine tries to use as many
characters as it can before it encounters the next one, which is the
**last** ']', hence only one match.

To get your three matches, you could replace '.*' with '.*?' which
makes the * non greedy.
