Detailed output with var_dump()

Learn to display a variable's type and value in detail with var_dump().

The var_dump() function

var_dump() shows a variable's type and value in detail. It is the most common way to debug.

Example: var_dump("Book"); prints string(4) "Book".

For numbers the value appears directly: var_dump(42); prints int(42).

For bool you see bool(true) or bool(false), not the 1 or empty string that echo produces.

PHP has two common output functions: print_r and var_dump.

print_r gives simpler output; it does not show type info. It is readable for arrays but can mislead you with bool and null.

var_dump shows type, length and value completely. When debugging, always prefer var_dump.

Tip: echo only prints the value; it gives no type info. Use var_dump when you need type details.

Assign "Guide" to $title and 240 to $pages. Write a var_dump() call for each variable.

Show example solution

Write one var_dump(...) call per line.
Example solution:
<?php
$title = "Guide";
$pages = 240;
var_dump($title);
var_dump($pages);
