Use an expression to select an array value in PHP. It's handy for quick output logic. Update: it's a bit too clever, perhaps, versus using the tenary operator.
```
$classes .= [ ' sort-default', ' sort-custom' ][ has_custom_sort( $post ) ];
```

Basic routing using REQUEST_URI

Sander March 21, 2023 at 12:41 pm
So for nginx it is not straightforward to setup PHP-FPM so that PATH_INFO is correctly populated. Lamb uses the following /index.php/some/other type routing, where /some/other should be the PATH_INFO. Instead I want to make setup for a variety of web-servers straightforward, so I've switched to the more robust REQUEST_URI. This simplifies nginx configuration and Caddy and the PHP built-in web-server are compatible.

REQUEST_URI contains everything after the domain name, including the query string, so that needs to be removed:
```
$request_uri = '/home';
if ( $_SERVER['REQUEST_URI'] !== '/' ) {
    $request_uri = strtok( $_SERVER['REQUEST_URI'], '?' );
}
```
We can see that for a request for the root of the site, REQUEST_URI returns / whereas PATH_INFO would be empty, so the code above takes that into account. We can then deduct a router action as follows:
```
$action = strtok( $request_uri, '/' );
```
Once the $action is known, it can be checked against an allowed list of actions:
```
switch ( $action ) {
    case 'edit':
        ...
        break;
    default:
        respond_404();
        break;
```

How to develop a library and a project in PHP concurrently

Sander January 12, 2022 at 1:44 pm
I keep forgetting the best way to do this, so thought it best to write it down.

Suppose you are building a library and an example project that implements it. You can do this in a single repository with an example folder, for small examples.

But for larger examples you might want to use a separate repository, with it's own issues and documentation.

This can make it a hassle to work with the library and keep the project in sync.

Let's say these are mylibrary and myproject which is using the library. Let's assume you're using PHP and Composer. mylibrary is at version 0.1 but there are newer commits in the develop branch.

Require a Git repository
```
$ cd myproject
$ composer config repositories.me vcs https://github.com/me/mylibrary
$ composer require me/mylibrary:0.1 --prefer-source
```
--prefer-source means Composer will install from source if there is one, the result is a git repository.

Switch to the develop branch

Once installed it's then easy to switch to any other branch you want to work on:
```
$ cd vendor/me/mylibrary; git switch develop
```
You don't have to register the repository with packagist if you follow this workflow! As a bonus when after you run composer update in myproject the mylibrary directory sticks with the branch.

Don't think you want to make it this simple to pipe potentially unsafe input to the shell #PHP <a href="http://php.net/manual/en/language.operators.execution.php">[http://php.net/manual/en/language.operators.execution.php</a><p>](http://php.net/manual/en/language.operators.execution.php</a><p>) </p>
PHP 5.5 drops support for Windows XP / Server 2003

Sander July 13, 2012 at 11:28 pm

PHP 5.5 will no longer support Windows XP and 2003. Those systems are around a decade old, so PHP is pulling the plug on them.

It was already mentioned on the PHP 5.4 release changelog. It makes sense, but I’m sure it will cause some issues with organisations who have not been paying attention. I would encourage all developers to sign up for the PHP Announcements mailinglist. #link #php

[Patch] CodeIgniter Helper class patch for Textile

Sander April 26, 2011 at 3:57 pm
For those that do not follow me on twitter (@pacifika), I've created a patched version of Textile, the html generator alternative to Markdown, to make it easier to use in CodeIgniter projects. I have provided the patch and patched Textile on support forums of both projects.

[Patch] CodeIgniter Helper class patch for classTextile.php · Textpattern CMS Support Forum.

After patching, you can just use Textile like this:
```
$this->load->helper('textile');
$text = Textile("Dude this is *my* code!");
```
For more information read the post on the forums!

Rotate PHP logs

Sander February 28, 2011 at 2:38 pm
Our php.log was nearing 550MB so I was investigating how to rotate the logs. The easiest solution seems to be using logrotate (ubuntu linux) with a script like follows.
```
sudo nano /etc/logrotate.d/php5
```
```
/var/log/php5/*.log {
```
```
  #rotate daily
  daily
```
```
  #keep 14 days
  rotate 14
```
```
  missingok
  nocompress
  sharedscripts
  postrotate
  apache2ctl graceful
  endscript
```
```
}
```
You can check the configuration by running logrotate --force /etc/logrotate.d/php5
