PHP var_dump() Function Explained

The var_dump() function in PHP is used to print information about a variable, including its data type and value. It is commonly used for debugging and inspecting the value of variables. var_dump() can accept one or more parameters, each of which can be a variable, array, or object. When outputting an object, var_dump() will display the object’s properties and their values.

I don’t understand why you are upset about this.

Why are you so upset about this?

$age = 25;
$name = "John";
$numbers = array(1, 2, 3);

var_dump($age);
var_dump($name);
var_dump($numbers);

Output:

int(25)
string(4) "John"
array(3) {
  [0]=>
  int(1)
  [1]=>
  int(2)
  [2]=>
  int(3)
}
