Can you assign multiple variables at once in PHP like you can with Java?
提问by transformerTroy
I want to create 5 variables of type array all at once. Is this possible? In Java I know you can, but can't find anything about PHP. I'd like to do something like this:
我想一次创建 5 个数组类型的变量。这可能吗？在 Java 中，我知道您可以，但找不到有关 PHP 的任何信息。我想做这样的事情：
$var1, $var2, $var3, $var4, $var5 = array();

Yes, you can.
是的你可以。
$a = $b = $c = $d = array();
回答by Miquel
$c = $b = $a;
is equivalent to
相当于
$b = $a;
$c = $b;
therefore:
所以：
$var1 = $var2 = $var3 = $var4= $var5 = array();

Since PHP 7.1 you can use square bracket syntax:
自 PHP 7.1 起，您可以使用方括号语法：
[$var1, $var2, $var3, $var4, $var5] = array(1, 2, 3, 4, 5);

I prefer to use the listfunction for this task. This is not really a function but a language construct, used to assign a list of variables in one operation.
我更喜欢使用列表功能来完成这项任务。这不是真正的函数，而是一种语言结构，用于在一次操作中分配变量列表。
list( $var1, $var2, $var3 ) = array('coffee', 'brown', 'caffeine');
list( $var1, $var2, $var3 ) = array('coffee', 'brown', 'caffeine');
