我如何$_GET正确的ID
picture.php
if (!isset($_GET['id'])) {
header('location:/');
exit();
} else if (isset($_GET['id'])) {
print_r($_GET);
}
$_GET 输出
Array ( [page] => picture )
.htaccess
RewriteEngine On
RewriteBase /
RewriteRule ^([A-Za-z0-9-]+)/?$ /index.php?page=$1 [L]
RewriteRule ^([A-Za-z0-9-]+)/picture/?$ /picture/?id=$1 [L]
URL 格式：http://local.com/42/picture/
问题：如何制作$_GET['id']将打印 42 而不是 图片
picture.php
if (!isset($_GET['id'])) {
header('location:/');
exit();
} else if (isset($_GET['id'])) {
print_r($_GET);
}
$_GET output
Array ( [page] => picture )
.htaccess
RewriteEngine On
RewriteBase /
RewriteRule ^([A-Za-z0-9-]+)/?$ /index.php?page=$1 [L]
RewriteRule ^([A-Za-z0-9-]+)/picture/?$ /picture/?id=$1 [L]
URL format : http://local.com/42/picture/
Question : How to make the $_GET['id'] will print 42 and not the picture

L 标志会导致将已重写的 URL 重新注入到重写过程中。因此，当
/42/picture/被重写为/picture/?id=42时，它就会被重写为/index.php?page=picture>。您可以通过在其他规则前面放置一个规则来避免这种情况，该规则会停止每个可以映射到现有文件的路径的请求的重写过程：
The L flag causes a re-injection of the already rewritten URL into the rewriting process. So when
/42/picture/gets rewritten to/picture/?id=42it then gets rewritten to/index.php?page=picture.You can avoid this by putting a rule in front of your other rules that stops the rewriting process for every request that’s path can be mapped onto an existing file:
从
var_dump的输出来看，似乎第一个规则匹配，而不是第二个规则。您编写规则的顺序很重要，您可能应该恢复这两个规则。由于您的第一条规则较短。您可以查看文档以供参考。
From the output of your
var_dump, it seems the first rule is matching and not the second. The order you write rules matters, you should probably revert the two rules. Since your first rule is shorter.You can take a look at the documentation for your reference.
