iconv_strpos
ICONV_STRPOS(3) 1 ICONV_STRPOS(3)
iconv_strpos - Finds position of first occurrence of a needle within a haystack
SYNOPSIS
int iconv_strpos (string $haystack, string $needle, [int $offset], [string $charset = ini_get("iconv.internal_encoding")])
DESCRIPTION
Finds position of first occurrence of a $needle within a $haystack.
In contrast to strpos(3), the return value of iconv_strpos(3) 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.
PARAMETERS
o $haystack
- The entire string.
o $needle
- The searched substring.
o $offset
- The optional $offset parameter specifies the position from which the search should be performed.
o $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.
RETURN VALUES
Returns the numeric position of the first occurrence of $needle in $haystack.
If $needle is not found, iconv_strpos(3) will return FALSE.
Warning
This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on
Booleans for more information. Use the === operator for testing the return value of this function.
