In contrast to <function>strrpos</function>, the return value of
|
|
<function>iconv_strrpos</function> 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 <parameter>charset</parameter>.
