The iconv_strrpos() function is an inbuilt function in PHP that searches for the last occurrence of a substring within a string while taking the character encoding of the string into account. It is similar to the strrpos() function, but it supports multi-byte character sets.
Syntax:
int|false iconv_strrpos( string $haystack, string $needle, ?string $encoding = null )
Parameters: The function accepts three parameters that are described below:
- $haystack: This parameter is where we search for the last occurrence of a string.
- $needle: This parameter defines searching a sub-string in the $haystack parameter.
- $encoding: The character set to use. The default value is the internal encoding that will be used.
Return Values: The numeric position of the last occurrence of the substring within the string, or “false” if the substring is not found in the string.
Example 1: The following program demonstrates the iconv_strrpos() function.
PHP
<?php $str = "Hello world, hello universe!" ; $pos = iconv_strrpos( $str , "hello" ); echo $pos ; ?> |
Output:
13
Example 2: The following program demonstrates the iconv_strrpos() function.
