• Ayaz Shah: @u_mulder how can use it...?
• Rahul Dole: If you're developing a web service, then this server response will automatically appear as an 'object' using javascript. then you can use it like this: username.user
• Kohjah Breese: json_decode( $arrayToDecode ); # converts arrays to JSON.

Answer 1

This should do what you ask, it is just a case of converting the PHP arrays to a form that javascript can understand. You can use json_encode() to do that.

$DATATABLE_SEARCH_DATA_NAMES = array('username','byusers');
$DATATABLE_SEARCH_DATA_VALUE = array('user', 1);
$js1 = json_encode($DATATABLE_SEARCH_DATA_NAMES);
$js2 = json_encode($DATATABLE_SEARCH_DATA_VALUE);
//echo $js1.PHP_EOL;
//echo $js2.PHP_EOL;
echo "<script>\n";
echo 'var names = ' . $js1 . ";\n";
echo 'var values = ' . $js2 . ";\n";
echo "</script>\n";

Answer 2

say, you have a PHP array as this:

$arr = array("key1"=>"foo","key2"=>"bar");

the easiest way to put it to javascript is this:

var arr = <?php echo json_encode($arr); ?>;

ending with a JSON object.
