iconv_strrpos — Finds the last occurrence of a needle within a haystack

Beschreibung

iconv_strrpos(string $haystack, string $needle, ?string $encoding = null): int|false

Finds the last occurrence of a needle within a haystack.

In contrast to strrpos(), the return value of iconv_strrpos() is the number of characters that appear before the needle, rather than the offset in bytes to the position where the needle has been found. The characters are counted on the basis of the specified character set encoding.

Parameter-Liste

haystack

The entire string.

needle

The searched substring.

encoding

If encoding parameter is omitted or null, string are assumed to be encoded in iconv.internal_encoding.

If haystack or needle is not a string, it is converted to a string and applied as the ordinal value of a character.

Rückgabewerte

Returns the numeric position of the last occurrence of needle in haystack.

If needle is not found, iconv_strrpos() will return false.

Warnung

Diese Funktion kann sowohl das boolsche false zurückliefern, als auch einen nicht-boolschen Wert, welcher zu false ausgewertet wird. Weitere Informationen entnehmen Sie bitte dem Abschnitt über die boolschen Typen. Benutzen Sie deshalb den === Operator, um den Rückgabewert dieser Funktion zu überprüfen.
