iconv_strpos

Description

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 encoding.

Parameters

haystack

The entire string.

needle

The searched substring.

offset

The optional offset parameter specifies the position from which the search should be performed. If the offset is negative, it is counted from the end of the string.

encoding

If encoding parameter is omitted or null, 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() will return false.
