Data Types and the If-Else Construct in PHP

When using the if construct, you can compare strings as well. For example, let the variable $test store some string, like this:

php<?php
  $test = 'abc';
?>

Let's check if the content of the variable $test is equal to the string 'abc':

php<?php
  $test = 'abc';
  
  if ($test == 'abc') {
    echo '+++'; // this will work, because the variable is equal to 'abc'
  } else {
    echo '---';
  }
?>
