Reference assignment operator in PHP to assign a reference?

Let’s say we have the following value −

$nextValue=100; Let us take a new variable and assign a reference − $currentValue = &$nextValue; To assign a reference, use the reference assignment operator i.e. =&$anyVariableName in PHP.

The PHP code is as follows −

Example

Live Demo

<!DOCTYPE html>
<html>
<body>
<?php
$nextValue=100;$currentValue = &$nextValue; echo "Next Value=",$nextValue,"<br>";
echo "Current Value=",$currentValue,"<br>";$nextValue = 45000;
echo "After changing the value of next will reflect the current value because of =&","<br>";
echo "Next Value=",$nextValue,"<br>"; echo "Current Value=",$currentValue;
?>
</body>
</html>

Output

Next Value=100
Current Value=100
After changing the value of next will reflect the current value because of =>
Next Value=45000
Current Value=45000
