an array of parameter values

Question

function test()
{   
$content = "lang=en]text en|lang=sp]text sp";
$atts = explode('|', $content);
}

What I'm trying to do is to allow myself to echo $param[en] to get "text en", $param[sp] to get "text sp". Is that possible?

the $content is actually from a database record.

What method was used to encode the data in that string? It looks home-grown, but perhaps you can refer to the generating code? — Gustav Bertram

$param = array();
$langs = explode('|', $content);
foreach ($langs as $lang) {
    $arr = explode(']', $lang);
    $key = substr($arr[0], 5);
    $param[$key] = $arr[1];
}

This is if you are sure $content is well-formatted. Otherwise you will need to put in additional checks to make sure $langs and $arr are what they should be. Use the following to quickly check what's inside an array:

echo '<pre>'.print_r($array_to_be_inspected, true).'</pre>';

Hope this helps

if this is not hard coded string in $content

function test()
{   
   $content = "lang=en]text en|lang=sp]text sp"; 
   $atts = explode('|', $content);
   foreach($atts as $att){
      $tempLang = explode("]", $att);
      $params[array_pop(explode("=", $tempLang[0]))] = $tempLang[1];
   }

   var_dump($params);
}

I'd do it the same way, but used list( $key, $value) = explode( "]", $att); instead. Anyway +1.

I think in this case you could use regular expressions.

$atts = explode('|', $content);
foreach ($atts as $subtext) {
    if (preg_match('/lang=(\w+)\](\w+) /', $subtext, $regs)) {
        $param[$regs[0]] = $regs[1];
   }
}

Although it seems that you have a bad database structure if that value comes from a database - if you can edit it, try to make the database adhere to make the database normal.
