mb_strpos

(PHP 4 >= 4.0.6, PHP 5, PHP 7, PHP 8)

mb_strposFind position of first occurrence of string in a string

Description

mb_strpos(
    string $haystack,
    string $needle,
    int $offset = 0,
    ?string $encoding = null
): int|false

Finds position of the first occurrence of a string in a string.

Performs a multi-byte safe strpos() operation based on number of characters. The first character's position is 0, the second character position is 1, and so on.

Parameters

haystack

The string being checked.

needle

The string to find in haystack. In contrast with strpos(), numeric values are not applied as the ordinal value of a character.

offset

The search offset. If it is not specified, 0 is used. A negative offset counts from the end of the string.

encoding

The encoding parameter is the character encoding. If it is omitted or null, the internal character encoding value will be used.

Return Values

Returns the numeric position of the first occurrence of needle in the haystack string. If needle is not found, it returns false.

Changelog

Version Description
8.0.0 needle now accepts an empty string.
8.0.0 encoding is nullable now.
7.1.0 Support for negative offsets has been added.
