在PHP中将多个变量分配给单个变量 [英] Assigning multiple variables to a single in PHP

问题描述

我想做的是从保存在variables.php文件中的一个变量中调用我的所有元标记.

我可以单独回显它们，但是我想为它们分配相同的名称，因此网页中的回显脚本较小.我知道这是您将相同的值分配给整数的方式，但是我找不到用字符串值做到这一点的解决方案(我认为它们是正确的字符串吗?)

$john = $ jane = 3;

我在尝试什么.

$metaAuthor = $metaDescription = $metaImage = $metaTitle =$meta;

当您不使用数字时，我认为它是一个不同的命令吗?

解决方案

每种数据类型，字符串，整数，数组等的工作方式都相同.

这里有一个小演示:

在您发表评论之后，您可能想要这样做:

$meta = $metaAuthor." ".$metaDescription." ".$metaImage ." ".$metaTitle;

数组的工作方式如下:

$meta = array("author" => $metaAuthor, "description" => $metaDescription );
echo $meta['author']; 

What I want to do is call all of my meta tags from one variable kept in the variables.php file.

I can echo them individually but I want to assign them all the same name so the echo script in the webpage is smaller. I understand that this is how you assign the same value to an integer but I cannot find the solution to do this with string values(I think they are string right?)

$john = $ jane = 3;

What I am trying.

$metaAuthor = $metaDescription = $metaImage = $metaTitle =$meta;

I assume its a different command when you are not using numbers?

解决方案

It is the same for every datatype, strings, ints, arrays, etc work all the same.

A little demo here:

Af of your comment you probably want this:

$meta = $metaAuthor." ".$metaDescription." ".$metaImage ." ".$metaTitle;

An array works like this:

$meta = array("author" => $metaAuthor, "description" => $metaDescription );
echo $meta['author'];
