iconv_strpos — Finds position of first occurrence of a needle within a haystack
$haystack
, string $needle
[, int $offset
= 0 [, string $charset
= ini_get("iconv.internal_encoding") ]] ) Finds position of first occurrence of a needle
within a haystack
.
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
.
haystack
The entire string.
needle
The searched substring.
offset
The optional offset
parameter specifies the position from which the search should be performed.
charset
If charset
parameter is omitted, 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 first occurrence of needle
in haystack
.
If needle
is not found, iconv_strpos() will return FALSE
.
This function may return Boolean FALSE
