Yes php 4.4.7 server support php 5 files. But most of the php 5 features are not supported by php 4.4.7 version
PHP files are HTML files with any amount of PHP intermingled into it, so the file can be empty or only contain HTML and be valid, yes.
PHP files extension is .php
PHP is a programming language. Unless 3D max has a programming interface of some kind, you can't open php files with it. You can open a PHP file with notepad or any other text editor.
You can find PHP documentation on the official PHP website at php.net. The website has comprehensive documentation on PHP functions, classes, and features, as well as user-contributed notes and examples.
You can use the GD extension for PHP to edit image files.
No it does not support PHP. PHP is a server side processing language while Real Player is a media player which playes audio and video files. Maybe it can play audio and video files located in php folder but that is limited to that.
It shouldn't.On further exploration this appears to be the result of a very slow & noisy connection (very old telephone wiring down our road) causing corruption in the file download. The files download correctly elsewhere.
To rename a file in PHP the easiest way to do it is to use the rename() function. <?php rename("before.txt", "after.html"); ?>
A PHP file will not be a video. Videos are commonly .wmv, .mov, .mp4, etc. PHP is a server scripting programming language. Since a PHP file is completely parsed on the server, you cannot download a PHP file, unless you use another script to enforce the download. But even that approach requires that the script be on the same server as the target one.
Download & Install a WAMP or XAMPP Server and everything you require to code in php comes with them. If you want to secure wamp or xampp you ought to change the php.ini file and mysql config files and change password for mysql and php localhost
You need to install PHP either on a pre built apache server such as xampp or download PHP directly from the website.
