假设我们具有以下值-
$nextValue=100;
让我们采用一个新变量并分配一个引用-
$currentValue = &$nextValue;
要分配引用，请使用引用分配运算符，即PHP中的=＆$anyVariableName。
PHP代码如下-
<!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>
输出结果
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
