Question

I want to do something like bellow using php:

$turl=array(trim($params->get('c2')));
$tname=array(trim($params->get('cn2')));

and want to display each $turl with each $tname.

I tried like this:

$result=array_combine($turl,$tname);
print_r($result);

but given result as:

Array ( [http://184.107.144.218:8282/,http://184.107.144.218:8082/] => ABC Radio,AHH Radio )

But I want like this:

Array ( [http://184.107.144.218:8282/=> ABC Radio,
http://184.107.144.218:8082/=> AHH Radio )

Thanks in advance

Answer 1

maybe you want to use a code similar to this:

$turl  = explode(',',trim($params->get('c2')));
$tname = explode(',',trim($params->get('cn2')));

$result=array_combine($turl,$tname);
print_r($result);

The error seems to be into the $turl and $tname arrays creation as array combine should work as intended

Obviously I would add several checks, as, for example, Have the two arrays the same size?

Addendum
In your comment you give me a specimen of what $params->get returns if called with parameters ‘c2’ and ‘cn2’.

$params->get('c2')="hoicoimasti.com,google.com" 
$params->get('cn2')="hoicoi,google".

The example code I gave you do what required, or at leas what I was thinking you are trying to obtain. A different code with a different result is:

$turl  = explode(',',trim($params->get('c2')));
$tname = explode(',',trim($params->get('cn2')));

$result=array_map(function($x,$y){return $x.','.$y;},$turl,$tname);
print_r($result);

or, if you want to obtains a single string:

$result=join(',',array_map(function($x,$y){return $x.'=>'.$y;},$turl,$tname));
print_r($result);

You can obtain any desired result modifying one of the previous example.

To encase the results in an option you need a slight variation of the array_map user function:

$result=join("\n",array_map(
    function($x,$y){
        return "<option>$x=>$y</option>";
    },
    $turl,
    $tname
));
print_r($result);

PHP < 5.3 version
Put this function declaration somewhere in the global scope

function formatOption($x,$y){
    return "<option>$x=>$y</option>";
};

and then your code will become:

$result=join("\n",array_map( 'formatOption', $turl, $tname));
print_r($result);

If possible I won’t clutter the global namespace with function like formatOption,
but when anonymous function are not available

Reference:

• array_map
• join
