iconv_strpos --  Finds position of first occurrence of a needle within a haystack.


int iconv_strpos ( string haystack, string needle, int offset [, string charset])

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

The optional offset parameter specifies the position from which the search should be performed.

If needle is not found, iconv_strpos() will return FALSE.


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.

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

In contrast to strpos(), the return value of iconv_strpos() 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 charset.

If charset parameter is omitted, string are assumed to be encoded in iconv.internal_charset.
