strpos() won't accept whitespaces?

[MrAshburn]

Hy ya'll!

 

I've been trying to programatically read a string, but with no success.

 

function get_between($input, $start, $end) {
  $substr = substr($input, strlen($start)+strpos($input, $start), (strlen($input) - strpos($input, $end))*(-1));
  return $substr;
}

$string =  'open -greetings hello -bye seeya';
echo get_between($string, '-greetings ', ' -bye'); // Output: hello
echo get_between($string, '-greetings ', ' -'); // Outputs nothing
echo get_between($string, '-greetings ', ' '); // Outputs nothing
}

 

It turns out that I don't know if "-bye" will always follow the value of "-greetings", so I can't call everything in between like the first way even tough it works fine in this example. Given that those values will always be a single word, I can use a whitespace as a delimiter to the right, but for some reason it won't return anything whatsoever, not even an error code.

 

Any ideas how to get it done?

 

Txs a bunch!

Hello there,

 

As for the subject: strpos does accept whitespaces. your substr's length parameter is just wrong since you're getting the length from the whole string.

 

Anyways, my version of the function:

function get_between($input, $start, $end) {
$start = substr($input, strpos($input,$start) + strlen($start));
return substr($start, 0, strpos($start, $end));
}

Should work just neatly.

 

There's also a better way to get the content between two clues:

function get_between($content,$start,$end){
    $r = explode($start, $content);
    if (isset($r[1])){
        $r = explode($end, $r[1]);
        return $r[0];
    }
    return '';
}

 

Hope this helps.

Yay, that did the trick!  I'm using your version from now on as that code looks cleaner and effective.

 

Thank you so much, yo! You saved my weekend!
