PHP » Strings » strpos()
- Syntax:

- s

Returns the position of a substring.
strpos() returns the position of the first occurrence of a string within another string. An offset can optionally be used to set a position where the search should start. If no occurrence is found, FALSE is returned.
Examples
Code:
<?php
print 'Position of "world": ' . strpos("Hello world", "world") . "<br>";
if (!strpos("Hello world", "Hello", 5))
print '"Hello" not found after position 5';
?> Output:
Position of "world": 6
"Hello" not found after position 5 Explanation:
This code shows how strpos() can be used both with and without the offset parameter.
