Question

I have an array that contains possible request URIs. Some of the array values could contain comma delimited URIs:

array(
     0 => 'GET /, GET /something',
     1 => 'GET /login',
     2 => 'GET /user/profile',
)

Let’s say I want to find the key that contains “GET /something”. How can I use preg_grep to do this? Currently, I’m trying this:

preg_grep('/(.*)GET \\'.$uri.'(.*)/', $array);

However, I just get an empty array back. Any idea what I’m doing wrong?

Answer 1

Rather than having $uri in your string for preg_grep, concat it into a $pattern var first (for ease of reading mostly plus you can echo it and check as the above comment suggested):

$uri = 'something';
$pattern = '/(.*)GET \/'.$uri.'(.*)/';
$array = preg_grep($pattern, $starting_array);
print_r($array);

As to answer your question specifically, you escaped the wrong type of slash :p
