搜索一个子字符串，如果它在最后，则返回true

Question

I would like to search for a substring in php so that it will be at the end of the given string. Eg on string 'abd def' if I search for def it would be at the end, so return true. But if I search for abd it will return false since it is not at the end.

Is it possible?

Answer 1

Assuming whole words:

$match = 'def';
$words = explode(' ', 'abd def');

if (array_pop($words) == $match) {
  ...
}

Or using a regex:

if (preg_match('/def$/', 'abd def')) {
  ...
}
