Returns the numeric position of the first occurrence of needle in the haystack string. Unlike strpos(), stripos() is case-insensitive.
Note that the needle may be a string of one or more characters.
If needle is not found, stripos() will return boolean FALSE.
Waarschuwing |
Deze functie kan FALSE teruggeven, maar kan ook een andere waarde die naar FALSE evalueert teruggeven. Gebruik de === operator om de teruggeven waarde van deze functie te testen. |
If needle is not a string, it is converted to an integer and applied as the ordinal value of a character.
The optional offset parameter allows you to specify which character in haystack to start searching. The position returned is still relative to the the beginning of haystack.
