php写pkcs5报错解决办法

php写pkcs5报错
这是代码：

function pkcs5_pad ($text, $blocksize)<br />	{		<br />		$pad = $blocksize – (strlen($text) % $blocksize);<br />		return $text . str_repeat(chr($pad), $pad);<br />	}

报错：Parse error: syntax error, unexpected T_STRING

报错的句子是：$pad = $blocksize – (strlen($text) % $blocksize);

什么原因啊？

------解决方案--------------------
有非法字符

function pkcs5_pad($text, $blocksize){<br />  $pad = $blocksize - (strlen($text) % $blocksize);<br />  return $text . str_repeat(chr($pad), $pad);<br />}
