Returns the numeric position of the last occurrence of
needle
in the
haystack
string. Unlike
strrpos(), strripos() is
case-insensitive. Also note that string positions start at 0, and not
1.
Note that the needle
may be a string of one or
more characters.
If needle
is not found, FALSE is returned.
Advarsel |
Denne funktion returnerer muligvis en Boolean FALSE, men kan også returnere en ikke-Booleansk værdi som evalueres til FALSE, så som 0 eller "". Læs venligst sektionen om Booleans for mere information. brug === operatoren for at teste den værdi som returneres af denne funktion. |
The offset
parameter may be specified to begin
searching an arbitrary number of characters into the string.
Negative offset values will start the search at
offset
characters from the
start of the string.
