如何处理 .htaccess 规则中的特殊字符，如 : 和 , ？

Question

How i can get a and b values from urls like this:

http://127.0.0.1:8080/a:4522,b:846

I add this code to .htaccess for redirect all links to index.php but not working when use : and , character

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?path=$1 [NC,L,QSA]

For http://127.0.0.1:8080/a:4522,b:846 the request URI equals to /a:4522,b:846 . And the .htaccess directives put the request URI into path GET parameter. So you can simply parse $_GET['path'] in PHP:

<?php
$vars = [];
if ($path = isset($_GET['path']) ? $_GET['path'] : null) {
  foreach (explode(',', $path) as $part) {
    $tmp = explode(':', $part);
    if (count($tmp) == 2) {
      $vars[$tmp[0]] = $tmp[1];
    }
  }
}
var_dump($vars);

Output

array(2) {
  ["a"]=>
  string(4) "4522"
  ["b"]=>
  string(3) "846"
}

Sample configuration

/etc/apache2/vhosts.d/01_test_vhost.conf

<VirtualHost 127.0.0.12:80>
  ServerName apache-test.local
  ServerAdmin root@localhost
  DocumentRoot "/var/www/apache-test.local/public"

  ErrorLog "/var/www/apache-test.local/logs/error.log"
  CustomLog "/var/www/apache-test.local/logs/access.log" common

  <Directory "/var/www/apache-test.local/public">
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule . index.php [L]
    SetHandler application/x-httpd-php
  </Directory>
</VirtualHost>

/var/www/apache-test.local/public/.htaccess

Just as in your question.

/var/www/apache-test.local/public/index.php

The PHP code above.
