Web based File Manager in PHP, Single File and light weight
Tiny PHP File Manager
It is a simple, fast and small file manager with single php file. It is also a web code editor. It'll run either online or locally, on Linux, Windows or Mac based platforms. The only requirement is to have PHP 5.5+ available.
...Can also "compile" (run generate.py) from within Lazarus - if a syntax error is detected, the code editor jumps to the JavaScript file and line where the error is located.
Also includes full source code for the Unicodum demo app. This is a Unicode viewer consisting of a qooxdoo-based mobile client and a choice of Pascal (FCGI) or PHP server app.
