Description:
------------
For pattern: .* there is an empty match at the end of the string.
Reproduce code:
---------------
$p1='/.*/';
$p2='/.*$/';
$p3='/^.*/';
$p4='/^.*$/';
$test='some text';
function test($p,$t)
{
preg_match_all($p,$t,$m,PREG_SET_ORDER);
echo $p.'<br />';
if (count($m)==1)
echo '<div style="color: green;">ok</div>';
else
echo '<div style="color: red;">bug</div>';
echo '<pre>'.var_export($m,true).'</pre>';
echo '<br /><br />';
}
test($p1,$test);
test($p2,$test);
test($p3,$test);
test($p4,$test);
Expected result:
----------------
I'm expecting one match in the preg_match_all result array, and I will
get two instead of one. The second match is empty.
Actual result:
--------------
