Xdebug additionally provides credentials for PHP scripts, code coverage analysis, and good opportunities to interactively fix scripts using a computer interface program. Xdebug is additionally offered through the PHP Extension Community Library (PECL), which is often pronounced “pickle.”The var_dump() function is used to display data for a couple of variables. It works with the display of structured data such as the kind and value of a given variable. Arrays and object area are measured recursively with indented values indicating the structure.
var_dump - dumps information about a variable.Syntax:
void var_dump ($exp)Parameters:This function takes one parameter, $exp,which contains one variable or expression containing many variables separated by scopes of any kind.Type return:this function has no return type.

Arrays and objects are explored recursively with indented values pointing to the structure.Example 1:
$a = array (1, 2, array ( "a" , "b" , "c" )); var_dump ( $a ); ?> Exit:array (3 ) {[0] = > int (1) [1] = > int (2) [2] = > array (3) {[0] = > string (1) "a" [1] = > string (1) "b" [2] = > string (1) "c"}} Example 2: $b = 3.1; $c = true; var_dump ( $b , $c ); ?> Exit:float (3.1 ) bool (true)
