The 0 you are getting is not false it is because the targeted value is the first value of your string.

Returns the position of where the needle exists relative to the beginning of the haystack string (independent of offset). Also note that string positions start at 0, and not 1.

http://php.net/manual/en/function.strpos.php

Demo:

echo strpos('asdf/sfsdf/abc/this', 'sfsdf/');

Output:

5

because the sfsdf/ starts at the 6th position.

Use stristr instead.

Returns the matched substring. If needle is not found, returns FALSE. 

<?php

if(stristr('sfsdf/abc/this', 'sfsdf/'))
{
    echo 1;
}
else
{
    echo 0;
}
