.htaccess重写规则不起作用（启用重写模块）

I am trying to get the value of $_GET['pid'] on the products.php page, looks like it's not working for me, any help would be appreciated.

.htaccess rewrite rule as follows

RewriteEngine On
RewriteRule ^products/([0-9]+)$ /products.php?pid=$1 [NC,L]

index.php

<?php 
$i=1;
while($i <= 10){
    echo '<a href="products.php?pid='.$i.'">Products '.$i.'</a><br />';
    $i++;
}
?>

products.php

<?php 
if(!isset($_GET['pid'])){
    header('location : index.php');
}
else if(isset($_GET['pid'])){
    echo 'Product id - '.$_GET['pid'];
}
?>

You mean the links are not shown correctly? Your php file has to output the links, which mod_rewrite "translates" later. See example below:

<?php 
$i=1;
while($i <= 10){
echo '<a href="products/'.$i.'">Products '.$i.'</a><br />';
$i++;
}
?>

We use Htaccess to rewrite "ugly" URL's to shorter and prettier.In your code, you change your htaccess.

RewriteEngine On
RewriteRule ^(.*)$ products.php?pid=$1 [QSA,L]

Then change your URL's.

  <?php 
       $i=1;
       while($i <= 10){
       echo '<a href="products.php/'.$i.'">Products '.$i.'</a><br />';
       $i++;
      }
   ?>
