How can i get the output with newline formatted ?

[PFMaBiSmAd 131]

Output <pre> </pre> tags around the print_r/var_dump statement.

try:

echo "<pre>";
var_dump($var);
echo "</pre>";

 

Output <pre> </pre> tags around the print_r/var_dump statement.

beat me to it.

Can you post the full code ?

try:

echo "<pre>";
var_dump($var);
echo "</pre>";

Is there any shortcut way to write these three lines ? echo '<pre>'; var_dump($var); echo '</pre>';

not really, guess you could make your own function if you're using var_dump a lot?

function custom_vardump($var) {
  $var_dump = '';
   if(isset($var)) {
      $var_dump .= "<pre>";
      $var_dump .= var_dump($var);
      $var_dump .= "</pre>";  
   } else {
      $var_dump .= "Variable doesn't exist!";
   }
   return $var_dump;
}

$somerandomvar = array("somekey" => 'somevar');
echo custom_vardump($somerandomvar);
