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...

Functions (Built-in & User-defined)

  Functions in PHP are blocks of code designed to perform a specific task. They help make code reusable, organized, and easier to maintain. PHP provides built-in functions for common tasks, and also allows you to create your own user-defined functions . Built-in Functions PHP has hundreds of built-in functions that perform predefined operations such as string manipulation, mathematical calculations, and array handling. Example (Built-in Functions): <?php // String length echo strlen("Hello World"); // Outputs: 11   // Find maximum value in an array echo max(10, 20, 30); // Outputs: 30   // Convert string to uppercase echo strtoupper("php is awesome"); // Outputs: PHP IS AWESOME ?> User-defined Functions You can create your own functions to execute code whenever needed. This helps reduce repetition and makes programs easier to read. Syntax: function functionName($parameter1, $parameter2) {     // Code to...
