I'm coding a small CMS to get a better understanding of how they work and to learn some new things about PHP. I have however come across a problem.

I want to use mod_rewrite (though if someone has a better solution I'm up for trying it) to produce nice clean URLs, so can instead be

By my understanding I need to alter my .htaccess file each time I add a new page and this is where I strike a problem, my PHP keeps telling me that I can't update it because it hasn't the permissions. A quick bit of chmod reveals that even with 777 permissions it can't do it, am I missing something?

My source for mod_rewrite instructions is currently this page here incase it is important/useful.



One approach is to rewrite everything to a handling script

RewriteEngine on
RewriteBase /

# only rewrite if the requested file doesn't exist
RewriteCond %{REQUEST_FILENAME} !-s 

# pass the rest of the request into index.php to handle     
RewriteRule ^(.*)$ /index.php/$1 [L]

so if you have a request to http://yourserver/foo/bar/

what you actually get is a request to http://yourserver/index.php/foo/bar - and you can leave index.php to decide what to do with /foo/bar (using $_SERVER['PATH_INFO'] -tom)

You only need to modify .htaccess the first time. All future requests for inexistent files can then be handled in PHP.

You might also find the docs for mod_rewrite useful - but keep it simple or prepare to lose a lot of sleep and hair tracking down obscure errors.

Basically what people try to say is, you can make a rewrite rule like so:

RewriteRule ^(.*)$ index.php?params=$1 [NC, QSA]

This will make your actual php file like so:


And your actual URL would be like so:

And in your PHP file you could access your params by exploding this like so:


$params = explode( "/", $_GET['params'] );
for($i = 0; $i < count($params); $i+=2) {

  echo $params[$i] ." has value: ". $params[$i+1] ."<br />";

Ah, okay. Interesting. It seems there is a special solution for keeping that ampersand specifically escaped. Use the [B] flag for Rewriterules.

RewriteRule ^static/(.*)$ /index.php?static=$1 [L,B]

This is supposed to urlencode special characters when interpolating the $1 placeholder. It only works with Apache 2.2 however I believe.

Found a few references:

It is probably not the best thing to do. You need to at least check out your PHP error log for things going wrong ;)

# PHP error handling for development servers
php_flag display_startup_errors off
php_flag display_errors off
php_flag html_errors off
php_flag log_errors on
php_flag ignore_repeated_errors off
php_flag ignore_repeated_source off
php_flag report_memleaks on
php_flag track_errors on
php_value docref_root 0
php_value docref_ext 0
php_value error_log /home/path/public_html/domain/PHP_errors.log
php_value error_reporting -1
php_value log_errors_max_len 0

If you want to exclude files based on regular expressions, you could use FilesMatch instead of Files, e.g.:

<FilesMatch ^((home|test|file).php$|mysecretfolder|asecretpicture.jpe?g)$>
