Operators (Arithmetic, Comparison, Logical)
Operators in PHP are symbols that perform operations on variables and values. They are essential for performing calculations, comparing values, and making logical decisions in your code. PHP supports several types of operators, including arithmetic, comparison, and logical operators. Arithmetic Operators Arithmetic operators are used to perform basic mathematical operations. Example: <?php $a = 10; $b = 3; echo $a + $b; // 13 echo $a - $b; // 7 echo $a * $b; // 30 echo $a / $b; // 3.3333 echo $a % $b; // 1 (modulus) echo $a ** $b; // 1000 (exponentiation) ?> Comparison Operators Comparison operators are used to compare two values. They return true or false . Example: <?php $x = 5; $y = 10; var_dump($x == $y); // false var_dump($x != $y); // true var_dump($x === $y); // false (checks value and type) var_dump($x !== $y); // true var_dump($x > $y); // false var_dum...
