PHP 中引用赋值运算符如何赋值给引用?

假设我们有以下值 −

$nextValue=100;

我们取一个新变量并赋值给引用 −

$currentValue = &$nextValue;

要赋值引用,请使用引用赋值运算符,即 PHP 中的 =&$anyVariableName。

PHP 代码如下 −

示例

<!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>

输出

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
