PHP: strStart and strEnd functions

Tip by NetGuy | 29/03/2014 at 20:10

When programming in PHP, often, I am missing a simple function to check whether a string is starting or ending with a specific string or character. In other words, something like strStart or strEnd well known from other programming languages.

Of course, you can solve this problem by using substr() or strpos(), but it is much more easier if you have the following functions:

function strStart($s, $search) {
  return substr($s, 0, strlen($search)) === $search; 
}

function strEnd($s, $search) {
  return substr($s, -strlen($search)) === $search;
}

A call of this functions can look like this, for example:

$s = "abcdef";

if (strStart($s, "abc")) {  }  // true
if (strEnd($s, "def"))   {  }  // true

As a first paramater you are passing the string you would like to check, as a second parameter you are passing the search string.
