The Else Construct
The else construct is part of the conditional if construct and is executed when the main condition is false. It should always follow after an if or elseif block.
Syntax
if (condition) {
// code if true
} else {
// code if false
}
Example
Check if 5 is greater than 3:
<?php
if (5 > 3) {
echo 'True';
} else {
echo 'False';
}
?>
Code execution result:
'True'
Example
Check if 2 is less than 1:
<?php
if (2 < 1) {
echo 'True';
} else {
echo 'False';
}
?>
Code execution result:
'False'
Example
Usage with elseif:
<?php
$num = 0;
if ($num > 0) {
echo 'Positive';
} elseif ($num < 0) {
echo 'Negative';
} else {
echo 'Zero';
}
?>
Code execution result:
'Zero'
