Var_Dump confusion

Question

The input code is

<? php

$var1= "Hello world";

var_dump ($var1);

?>

the supposed output is

srting(11) "Hello world"

but the displayed result is

c:\wamp64\WWW\PHPCourse\Data_Type.php:string 'Hello world' (length=11)

Why the directory of this file appeared?
and how to fix it?

Answer 1

This is because of xdebug overloading var_dump. If you edit your php.ini and set "xdebug.overload_var_dump=1" you will no longer get the filename and line number with var_dump. The default setting is 2, which includes the filename and line number with the variable info. A setting of 0 will disable the xdebug override altogether.

left click on "wampmanager" icon on windows tray, then select "PHP -> php.ini"

so now find for "xdebug.overload_var_dump", then equal that "1" and save, restart wamp server...
