iconv_strrposFinds the last occurrence of a needle within a haystack


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.



The entire string.


The searched substring.


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.


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

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


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.
