Making PHP var_dump() values display one line per

Question

When I echo var_dump($_variable), I get one long, wrapping line with all varable's and values like

["kt_login_user"]=>  string(8) "teacher1" ["kt_login_id"]=>  string(3) "973" ["kt_campusID"]=>  string(4) "9088" ["kt_positionID"]=>  string(1) "5" 

Is there a way I can make each value display on its own line for ease of reading? Something like this:

["kt_login_user"]=>  string(8) "teacher1" 
["kt_login_id"]=>  string(3) "973" 
["kt_campusID"]=>  string(4) "9088" 
["kt_positionID"]=>  string(1) "5"

Answer 1

I usually have a nice function to handle output of an array, just to pretty it up a bit when debugging.

function pr($data)
{
    echo "<pre>";
    print_r($data); // or var_dump($data);
    echo "</pre>";
}

Then just call it

pr($array);

Or if you have an editor like that saves snippets so you can access them quicker instead of creating a function for each project you build or each page that requires just a quick test.

For print_r:

echo "<pre>", print_r($data, 1), "</pre>";

For var_dump():

echo "<pre>", var_dump($data), "</pre>";

I use the above with PHP Storm. I have set it as a pr tab command.

var_export will give you a nice output. Examples from the docs:

$a = array (1, 2, array ("a", "b", "c"));
echo '<pre>' . var_export($a, true) . '</pre>';

Will output:

array (
  0 => 1,
  1 => 2,
  2 => 
  array (
    0 => 'a',
    1 => 'b',
    2 => 'c',
  ),
)
