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
