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(); ?> |
Output
1 2 3 4 5 6 7 8 9 10
