PHP Write PKCS5 Error

This is the code:

function Pkcs5_pad ($text, $blocksize) {$pad = $blocksize? (strlen ($text)% $blocksize); return $text. Str_repeat (Chr ($pad), $pad);}

Error: Parse error:syntax error, unexpected t_string

The sentence for the error is: $pad = $blocksize? (strlen ($text)% $blocksize);

What's the reason?

Reply to discussion (solution)

There are illegal characters

function Pkcs5_pad ($text, $blocksize) {  $pad = $blocksize-(strlen ($text)% $blocksize);  Return $text. Str_repeat (Chr ($pad), $pad);}
