How can I store the output of this function in a variable PHP

Question

How can I store the output of this function in a variable?

if (function_exists('qts_language_menu') )
{
  qts_language_menu('text');
}

So, I can echo $variable when needed i.e. <div>'.$variable.'</div>

You can do it like this (with a default value):

$variable = function_exists('qts_language_menu') ? qts_language_menu('text') : "default";

It seems, qts_language_menu is a Wordpress' plugin function which doesn't return a value, but ouput it directly. So, you need to capture it's output:

if (function_exists('qts_language_menu') )
{
  ob_start();
  qts_language_menu('text');
  $variable = ob_get_clean();
}

try this

$variable = "No Data";
if (function_exists('qts_language_menu') )
{
    $variable = qts_language_menu('text');
}

echo '<div>'.$variable.'</div>';

When I do a var_dump($variable); I get a NULL – user3231649 Jan 24 '14 at 11:44
what is doing your function `qts_language_menu` is it return anything? – Satish Sharma Jan 24 '14 at 11:51
using qts_language_menu(); will output the function where ever I put it in the code. When I store it as a variable the variable empty and the function prints. Not too sure what to do really – user3231649 Jan 24 '14 at 13:47
post here your function `qts_language_menu` – Satish Sharma Jan 25 '14 at 05:11

You can do it like:

function test(){    
    if (function_exists('qts_language_menu') ) {return qts_language_menu('text');}
    else {return "function doesnot exists";}
}
$result=test();
echo $result;
