PHP MYSQL Tips and Tricks

This is a small article containing tricks and tips I aquired by reading PHP 6 Text Book.

I was used isset() function to check whether these arguements are set or not. And also I need to check this is empty or not.

Here is another function to check both of this requirement at single line.

empty()

It checks if a variable has an empty value: an empty string, 0, NULL,or FALSE.

Example

if ( !empty($_POST[‘name’]) && !empty($_POST[‘comments’]) && !empty($_POST[‘email’]) ) {

echo “Yes”;

}
