I know PHP scripts don't actually compile until they are run. However, say I want to create a small simple program and compile it to a binary without requiring the PHP binary. How could I do this?
I've seen a few IDE's out there that would do this, but either they are all for windows or the Linux versions don't actually build properly.
What I would like is something like py2exe that does it in the script itself.
Check out phc: the PHP compiler
If you just want to run it like a script, you may not need to compile it per se, but just run it via the command line. Read running PHP via the command line.
There is this: http://www.bambalam.se/bamcompile/ but that compiles to Windows bytecode. There are a few others, but all I have seen will compile for windows only.Few More:

Edit: I almost forgot if your looking to make it work on linux without regard for windows you can just add
#!/usr/bin/php
to the top of the script and you should be able to run it from the command line. Don't forget to chmod +x the file first.
Have a look at Facebook's Hiphop-PHP. It's able to convert PHP code into C++ then compile it with g++. Apparently, they've even gotten it to successfully compile entire WordPress installations.

If I have a .php script, I can run it from the terminal using
php myscript.php
In my case I'm mostly working on macOS and Linux (Ubuntu 18.04) but generally this works everywhere where PHP is installed.
However, I would prefer to make my .php script executable (i.e. chmod u+x myscript.php) so I can run it directly.
In order for this to work in any environment, I have to put a PHP shebang at the top of my script. Problem: the php binary has different locations on different platforms.
After searching around through similar stackexchange topics, the closest, most 'universal' way of doing this seems to be:
#!/usr/bin/env php
Is this correct, or what's the idea behind this? In what situations can this fail, and are there any fallbacks?
Can any one please tell me how to run(compile and execute) a c file in php on windows(windows 8)?
I know that using exec() i can execute a compiled file but how to compile the c file in php?
I am using xampp.
I have tried with exec() but its not working.
You don't need to compile every time you want to run it. So you would typically compile it once on its own, no need for php, and then use it as you want it.
(You could certainly run the compilation command using exec, but I don't see the point, and I believe you are confused as well.)
If you want to run a source code given from web site, you must compile it, but it can't be done in php. You need a C compiler, for example gcc. Install gcc and from php you call
exec( "/path/to/gcc source_code.c" );
Trying to mess around with PHP, but I don't want to install IIS or Apache and was hoping for a small interpreter that I can pass the scripts to and have them run in like a console or something. Much like Lua does. Does this exist? When I go to download PHP it seems to only talk about running it on IIS or Apache.
PHP can be used on the command line. Just download and extract the executable.
Running can be done 3 ways: a file, supplied code or in an interactive shell
php file.php
php -r "echo 'hello';"
php -a
You can also install a pre-packaged server (e.g. XAMPP) or run your code online on various places (e.g. phpfiddle.org)
With PHP 5.1+ you have an interactive shell too:
launch php with -a parameter
php.exe -a
http://php.net/manual/en/features.commandline.interactive.php
I believe that PHP v5.4 comes with its own webserver built-in. Install that version and you should be fine. Though I really would like to know why you have problem with installing Apache (IIS sucks though).
EDIT:
As a few others have said, you can run PHP from the command line.
check out easyphp, a server for php development
http://php.net/cli
Alternatively, you can write your PHP scripts as you would normally (with some limitations),
And use the following command line:
C:\php.exe -f "D:\phpFile.php"
dtech's answer seems most fitting for the simple script-running things you're looking for. If you decide you want an actual web-server, with as little setup as possible, look at "XAMPP".
I am wondering if a PHP script can be executed from a shell command line.
Does a script executed from shell have the exact functionality if executed from the browser? or is there a difference in coding.
Is it better to run a script from shell for performance and also is it better to run it from windows or unix/linux
I am asking all these questions because, I am suppose to develop a PHP script that can fetch some data from http headers of some urls listed in a MySQL db and then store the data in the database.
Can you guys point me to the right direction please, Do I need ubuntu, or is there a shell that can run php from windows? all I have at the moment installed is WAMP, which has mysql, php and apache server.
I am sorry for being a novice.
thanks for your kind help

Yes

It won't have $_REQUEST and friends populated, and $_SERVER won't have server information in it.
Is it better to run a script from shell for performance
Maybe. It avoids the overhead of runnning a webserver. It stops you having cached versions in memory for faster re-execution.
and also is it better to run it from windows or unix/linux
Benchmark it.

There doesn't seem to be any need to involve a web server for that.

The standard Windows shell can.

You'll need the command line version of PHP. I've no idea if WAMP includes it or not.
I am wondering if a PHP script can be executed from a shell command line.
It's possible either by executing:
$ php -f your_script.php
Or by inserting #/usr/bin/env php into the first line of the script and by making it executable.
$ head -n 1 your_sript.php
#/usr/bin/env php
$ chmod +x your_script.php
$ ./your_script.php
Note: this example only works on UNIX systems.

You can use the same Syntax/Functions etc. The only difference is that there are command line arguments in $argv and some other values in the $_SERVER variable.

That doesn't really matter. For your usecase you don't really need a webserver, and a full featured GUI. The advantage of having a command line tool is, you can combine your program with other program available like grep etc.

You don't need ubuntu, you can also execute a shell script from windows. The PHP executable is located in the %PATH%. This question will help you in order to do this: https://superuser.com/questions/284342/what-are-path-and-other-environment-variables-and-how-can-i-set-or-use-them
Then simply open cmd.exe and execute a script using php -f your_script.php
Yes, PHP can be run from command line.
No, there aren't any differences in coding.
The only difference is that it's not Apache running the script, but the user you are currently logged in as. That could mean different privileges on certain maps and folders.
Yes you can execute PHP from the command line using:
/path/to/php.exe /path/to/script.php
The main difference is that it doesn't run through Apache, so you won't have things that rely on it (like some $_SERVER data).
Also it won't be subject to timeouts on the command line, unless you have a PHP limit set.
Take a look at http://php.net/manual/en/features.commandline.php for more info.
I'm tempted by Automator.app's ability to create contextual services in Mac OS X Snow Leopard. I would like to create some keyboard accessible shortcuts to manipulate text snippets by calling a shell script. However, Automator only suggests bash, Perl, Python and Ruby (among others) to allow this. But, since PHP also ships with Mac OS (and, to be honest, it's the only scripting language I fully master), I wonder why I can't run a PHP shell script.
This is just a hack, but how about creating a python, or ruby or perl or bash script that calls php command-line interpreter with the php script you want to execute?
For instance in bash would be as simple as this:
#!/bin/bash
php myscript.php
Now save it, give it permission for execution:
chmod +x my_bash_script.sh
And voilá. Automator can now run the bash script, which calls the php script.
dbr's solution above is excellent, but I found that it didn't work for me, perhaps due to a later change in the shell, php, or OS version (I'm using OS X 10.8). After a lot of head-scratching I found that the answer is to quote the heredoc marker.
A useful addition is to use the appropriate syntax to pass the arguments through to the php script. Putting all that together, I'm using:
php -- "$#" <<'EOF'
<?php
print_r( $argv );
?>
EOF
You can use the "Run Shell Script" action to run a PHP script. One self-contained way is to use <<EOF ... EOF to pass the script to the php command:
(I would strongly recommend learning Python, Ruby or Perl.. PHP does has some advantages for web-programming, but is just not intended for command-line scripting.. It's certainly doable, it'll just not be nearly as.. pleasant)
The list of shells that Automator supports is in
/System/Library/Automator/Run\ Shell\ Script.action/Contents/Resources/Shells.plist
You can follow this guy's instructions to add an entry for /usr/bin/php. You may want to copy the .action file to ~/Library/Automator first, and work on the copy instead.
Of course, it's probably easier to just wrap it in a bash script, as others have suggested.
Automator has a "Run Shell Script" Action just add it to your workflow and follow the instructions on the bottom left.
