PHP goto Statement

0 0 1 minute read

The goto statement is used to jump to another section of a program. It is sometimes referred to as an unconditional jump statement. The goto statement can be used to jump from anywhere to anywhere within a function.

Flowchart of goto statement:

Syntax:

statement_1;

if (expr)
       goto label;
statement_2;
statement_3;

label: statement_4;

Example 1: The following code demonstrates the goto statement.

PHP

<?php 
  
    // Function to check even or not 
    function checkEvenOrNot($num) { 
        if ($num % 2 == 0) 
          
            // Jump to even 
            goto even; 
        else
            // Jump to odd 
            goto odd; 
  
    even: 
        echo $num . " is even"; 
          
        // Return if even 
        return; 
    odd: 
        echo $num . " is odd"; 
    } 
  
    $num = 26; 
    checkEvenOrNot($num); 
  
?>

Output

26 is even

Example 2: This is another code to demonstrate the goto statement of PHP.

PHP

<?php 
  
    // Function to print numbers 
    // from 1 to 10 
    function printNumbers() { 
        $n = 1; 
          
        label: 
            echo $n . ' '; 
            $n++; 
            if ($n <= 10) 
                goto label; 
    } 
  
    printNumbers(); 
  
?>
