Find the position of the first occurrence of a substring in a string


Parametr Datový typ Výchozí hodnota Poznámka
$haystack string   The string to search in
$needle mixed   If needle is not a string, it is converted to an integer and applied as the ordinal value of a character.
$offset int 0 If specified, search will start this number of characters counted from the beginning of the string. Unlike {@see strrpos()} and {@see strripos()}, the offset cannot be negative.

Návratové hodnoty



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

Returns FALSE if the needle was not found.
