Bug description: strtok() treats repeat of characters as single occurance
Description:
------------
strtok() ignores repeats of "arg2" ie. needle, and treats it as a single
occurance, skipping all repetitions
Reproduce code:
---------------
$query = "wtf ? omg ? wtf ???, ?";
$arguments = array(1,2,3,4,5,6);
var_dump($query);
$sql = strtok($query,"?");
var_dump($sql);
$retval = "";
while ($sql!==false) {
$wasempty = empty($arguments);
$val = array_shift($arguments);
$retval .= $sql;
if (!is_null($val) || !$wasempty) {
$retval .= "'".$this->escape($val).'\'';
}
$sql = strtok("?");
var_dump($sql);
}
echo $retval;
Expected result:
----------------
string(22) "wtf ? omg ? wtf ???, ?"
string(4) "wtf "
string(5) " omg "
string(5) " wtf "
string(0) ""
string(0) ""
string(2) ", "
bool(false)
wtf '1' omg '2' wtf '3''4''5', '6'
Actual result:
--------------
string(22) "wtf ? omg ? wtf ???, ?"
string(4) "wtf "
string(5) " omg "
string(5) " wtf "
string(2) ", "
bool(false)
wtf '1' omg '2' wtf '3', '4'
