The 'PBse - Search Tool and Editor' is a PHP script which can be uploaded to a web directory for searching files and folders. There is a simple search available but for more advanced users regular expressions can be used. The number of displayed files can be limited and the result can be filtered. Searching for text patterns in the content of files is also possible. The list of files shows different information like file size, modification date and time. Text files can also be viewed with the text highlighting of 'Highlight.js' and they can be opened in a simple text editor. If the file is saved, a backup copy will be created. A user login restricts the access to the tool. The 'PBse' tool is a single PHP script and can be installed very easy.
