Description
int
strripos ( string haystack, string needle [, int offset])
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.

Questa funzione puņ
restituire il Booleano FALSE, ma puņ anche restituire un valore non-Booleano valutato
come FALSE, come ad esempio 0 o
"". Per favore fare riferimento alla sezione Booleans per maggiori
informazioni. Usare l'operatore
=== per controllare il valore restituito da questa
funzione. |
Esempio 1. A simple strripos() example
<?php
$haystack = 'ababcd';
$needle = 'aB';
$pos = strripos($haystack, $needle);
if ($pos === false) {
echo "Sorry, we did not find ($needle) in ($haystack)";
} else {
echo "Congratulations!\n";
echo "We found the last ($needle) in ($haystack) at position ($pos)";
}
?>
|
Outputs:
Congratulations!
We found the last (aB) in (ababcd) at position (2) |
|
offset may be specified to begin searching an
arbitrary number of characters into the string. Negative values will
stop searching at an arbitrary point prior to the end of the string.
