In this section We defined variable and its value. We can easily find Which type of data types is used. Let’s see our example.

Another Way We can See the data type in PHP (gettype() function).

Example Gettype () inbuilt PHP Function:

<?php

$variable = “Hello PHP”;

echo gettype($varable);

?>

gettype () function always shows the variable data type in PHP.So it is an easy way to find that which variable is which data type.
