I am having a difficult time getting my regular expression code to work properly in PHP. Here is my code:
$array = array(); // Used to satisfy the 3rd argument requirment of preg_match_all.
$regex = '/(012|345|678|987|654|321|123|456|789|876|543|210|234|567|765|432)/';
$subject = '123456';
echo preg_match_all($regex, $subject, $array).'<br />';
print_r($array);
When this code is ran it will output:
2
Array
(
[0] => Array
(
[0] => 123
[1] => 456
)
[1] => Array
(
[0] => 123
[1] => 456
)
)
What can I do so that it will match 123, 234, 345 and 456?
Thanks in advance!
