如何通过网页将参数传递到PHP脚本中? [英] How do I pass parameters into a PHP script through a webpage?
问题描述
每当网页加载时,我都会调用PHP脚本.但是,有一个参数需要运行PHP脚本(测试脚本时通常通过命令行传递).
I am calling a PHP script whenever a webpage loads. However, there is a parameter that the PHP script needs to run (which I normally pass through the command line when I am testing the script).
页面加载时,每次运行脚本时如何传递此参数?
How can I pass this argument every time the script is run when the page loads?
推荐答案
大概是在命令行中按如下方式传递参数:
Presumably you're passing the arguments in on the command line as follows:
php /path/to/wwwpublic/path/to/script.php arg1 arg2
...然后通过脚本访问它们:
... and then accessing them in the script thusly:
<?php
// $argv[0] is '/path/to/wwwpublic/path/to/script.php'
$argument1 = $argv[1];
$argument2 = $argv[2];
?>
通过HTTP传递参数(通过Web访问脚本)时,您需要做的是使用查询字符串并通过$ _GET超全局变量访问它们:
What you need to be doing when passing arguments through HTTP (accessing the script over the web) is using the query string and access them through the $_GET superglobal:
转到 http://yourdomain.com/path/到/script.php?argument1=arg1&argument2=arg2
...并访问:
<?php
$argument1 = $_GET['argument1'];
$argument2 = $_GET['argument2'];
?>
如果您希望脚本无论在哪里(从命令行或从浏览器)调用,都可以运行,则将需要以下内容:
If you want the script to run regardless of where you call it from (command line or from the browser) you'll want something like the following:
正如克苏鲁(Cthulhu)在评论中指出的那样,测试您在哪个环境中执行测试的最直接方法是使用
as pointed out by Cthulhu in the comments, the most direct way to test which environment you're executing in is to use the PHP_SAPI constant. I've updated the code accordingly:
<?php
if (PHP_SAPI === 'cli') {
$argument1 = $argv[1];
$argument2 = $argv[2];
}
else {
$argument1 = $_GET['argument1'];
$argument2 = $_GET['argument2'];
}
?>
