Question

I am trying to run the pagerank script that I found on http://www.getrank.org/pagerank-script/. But I get an error message when I try it. Error message below.

is this a legit php code?

...
function _strord($string){
for($i=0;$i $result[$i] = ord($string{$i});
return $result;
}
...

I get this error on the line where the for statement starts.

Parse error: syntax error, unexpected T_VARIABLE, expecting ';' in /home/Desktop/test/pagerank-checker.php on line 73

Thanks.

If you look at the source code of what’s written on that page you’ll see:

function _strord($string){<br>
   for($i=0;$i<strlen($string);$i++)<br>
       $result[$i] = ord($string{$i});<br>
   return $result;<br>
}<br>

The code has not been properly escaped, so the browser treats the text starting <strlen as the start of an HTML tag, and misses out some vital code…

Without the mark up it reads:

function _strord($string){
   for($i=0;$i<strlen($string);$i++)
       $result[$i] = ord($string{$i});
   return $result;
}

EDIT a cleaner implementation is this:

function _strord($string) {
    return array_map('ord', str_split($string, 1));
}
