Logical AND in PHP

The logical AND allows you to specify the simultaneity of conditions. In the following example, the condition will be met if the variable $num is greater than zero and simultaneously less than 10:

php<?php
  $num = 3;
  
  if ($num > 0 and $num < 10) {
    echo '+++';
  } else {
    echo '---';
  }
?>

Conditions can be imposed not on one variable, but on different ones. In the following example, the condition will be met if the variable $num1 is equal to 2 and simultaneously the variable $num2 is equal to 3:

php<?php
  $num1 = 2;
  $num2 = 3;
  
  if ($num1 == 2 and $num2 == 3) {
    echo '+++';
  } else {
    echo '---';
  }
?>
