strpos() public static method

Multibyte enabled version of strpos(). Not all adapters must support interpreting - thus applying - passed numeric values as ordinal values of a character.
See link: http://php.net/function.strpos.php
public static strpos ( string $haystack, string $needle, integer $offset, array $options = [] ) : integer
$haystack string The string being checked.
$needle string The string to find in the haystack.
$offset integer If specified, search will start this number of characters counted from the beginning of the string. The offset cannot be negative.
$options array Allows for selecting the adapter to use via the `name` options. Will use the `'default'` adapter by default.
return integer Returns the numeric position of the first occurrence of the needle in the haystack string. If needle is not found, it returns `false`.
