PHP var_dump () function

PHP var_dump function is to determine the type and length of a variable, and output the value of the variable, if the variable has a value to lose is the value of the variable and return data type.

Let's take a look at Var_dump syntax:

Var_dump (Var, var, bar);

Let's take a look at one of my examples just now.

$ta = 1;
$TB = ' t ';
Echo Var_dump ($ta, $TB);
?>

Output to

Int (1) string (1) "T"

The first is a number, which is int (1)

Simple, but note that the variables inside the var_dump must be present, and if the variable exists but the value is empty, it will return false;



What does the Php:var_dump () function do?

such as Var_dump ($get); What do you mean?
