I'm new to php and wanted to run php from command line. I have installed WAMP and set the "System Variables" to my php folder ( which is
When i go to
CMD -> Type
php -a and hit enter, it says
interactive mode enabled. But when I write
echo 'Hi'; it shows nothing.
I even don't see anything like 'php >" when i type
php -a and hit enter.
The PHP CLI as its called ( php for the Command Line Interface ) is called php.exe
It lives in
c:\wamp\bin\php\php5.x.y\php.exe ( where x and y are the version numbers of php that you have installed )
If you want to create php scrips to run from the command line then great its easy and very useful.
Create yourself a batch file like this, lets call it
PATH=%PATH%;c:\wamp\bin\php\phpx.y.z php -v
x.y.z to a valid folder name for a version of PHP that you have installed within WAMPServer
Save this into one of your folders that is already on your PATH, so you can run it from anywhere.
Now from a command window, cd into your source folder and run >phppath.
It should work like a dream.
Here is an example that configures PHP Composer and PEAR if required and they exist
@echo off REM ************************************************************** REM * PLACE This file in a folder that is already on your PATH REM * Or just put it in your C:\Windows folder as that is on the REM * Search path by default REM * - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - REM * EDIT THE NEXT 3 Parameters to fit your installed WAMPServer REM ************************************************************** set baseWamp=D:\wamp set defaultPHPver=7.4.3 set composerInstalled=%baseWamp%\composer set phpFolder=\bin\php\php if %1.==. ( set phpver=%baseWamp%%phpFolder%%defaultPHPver% ) else ( set phpver=%baseWamp%%phpFolder%%1 ) PATH=%PATH%;%phpver% php -v echo --------------------------------------------------------------- REM IF PEAR IS INSTALLED IN THIS VERSION OF PHP IF exist %phpver%\pear ( set PHP_PEAR_SYSCONF_DIR=%baseWamp%%phpFolder%%phpver% set PHP_PEAR_INSTALL_DIR=%baseWamp%%phpFolder%%phpver%\pear set PHP_PEAR_DOC_DIR=%baseWamp%%phpFolder%%phpver%\docs set PHP_PEAR_BIN_DIR=%baseWamp%%phpFolder%%phpver% set PHP_PEAR_DATA_DIR=%baseWamp%%phpFolder%%phpver%\data set PHP_PEAR_PHP_BIN=%baseWamp%%phpFolder%%phpver%\php.exe set PHP_PEAR_TEST_DIR=%baseWamp%%phpFolder%%phpver%\tests echo PEAR INCLUDED IN THIS CONFIG echo --------------------------------------------------------------- ) else ( echo PEAR DOES NOT EXIST IN THIS VERSION OF php echo --------------------------------------------------------------- ) REM IF A GLOBAL COMPOSER EXISTS ADD THAT TOO REM ************************************************************** REM * IF A GLOBAL COMPOSER EXISTS ADD THAT TOO REM * REM * This assumes that composer is installed in /wamp/composer REM * REM ************************************************************** IF EXIST %composerInstalled% ( ECHO COMPOSER INCLUDED IN THIS CONFIG echo --------------------------------------------------------------- set COMPOSER_HOME=%baseWamp%\composer set COMPOSER_CACHE_DIR=%baseWamp%\composer PATH=%PATH%;%baseWamp%\composer rem echo TO UPDATE COMPOSER do > composer self-update echo --------------------------------------------------------------- ) else ( echo --------------------------------------------------------------- echo COMPOSER IS NOT INSTALLED echo --------------------------------------------------------------- ) set baseWamp= set defaultPHPver= set composerInstalled= set phpFolder= set phpver= set phpFolder=
Call this command file like this to use the default version of PHP
Or to get a specific version of PHP like this
> phppath 5.6.30
I remember one time when I stumbled upon this issue a few years ago, it's because windows don't have readline, therefore no interactive shell, to use php interactive mode without readline support, you can do this instead:
C:\>php -a Interactive mode enabled echo "Hello, world!"; ^Z Hello, world!
After entering interactive mode, type using opening (
<?php) and closing (
?>) php tag, and end with control Z (
^Z) which denotes the end of file.
I also recall that I found the solution from php's site user comment: http://www.php.net/manual/en/features.commandline.interactive.php#105729
Try using batch file
- Open notepad
php -S localhost:8000
- save file as
- now click on
server.batfile your server is ready on
if you got error php not recognize any internal or external command
then goto environment variable and edit path to php.exe
The problem you are describing sounds like your version of PHP might be missing the readline PHP module, causing the interactive shell to not work. I base this on this PHP bug submission.
And see if "readline" appears in the output.
There might be good reasons for omitting readline from the distribution. PHP is typically executed by a web server; so it is not really need for most use cases. I am sure you can execute PHP code in a file from the command prompt, using:
There is also the phpsh project which provides a (better) interactive shell for PHP. However, some people have had trouble running it under Windows (I did not try this myself).
According to the documentation here,
readline is not supported under Windows:
Note: This extension is not available on Windows platforms.
So, if that is correct, your options are:
- Avoid the interactive shell, and just execute PHP code in files from the command line - this should work well
- Try getting phpsh to work under Windows
If you want to just run a quick code snippet you can use the -r option:
php -r "echo 'hi';"
-r allows to run code without using script tags
You can run php pages using php.exe
create some php file with php code and in the cmd write
"[PATH to php.ext]\php.exe [path_to_file]\file.php"
After few research, best solution was to use that info another stackoverflow thread to avoid ctrl+z input and also from the scree output.
So, instead of
php -a you should use
call "php.exe" -f NAMED_SCRIPT.php
OLD Readline not possible under Windows, so none of existent php shells written in php will work. But there's a workaround using -a interactive mode.
2 commmon problems here. You cannot see result until executes CTRL Z command to indicate the final of code/file like EOF. When you do, result in most cases is printed result and fast closed window. Anyway, you will be returned to cmd not the -a interactive mode.
Save this content into a .bat file, and define your PHP PATH into Windows variables, or modify php.exe to "full path to exe" instead:
:: :: PHP Shell launch wrapper :: @ECHO off call "php.exe" -a echo. echo. call "PHP Shell.bat"
This is a simple Batch launching -a mode of php.exe. When it launchs php, stop script even no pause is wrote because is "into" the interactive waiting for input. When you hit CTRL Z, gets the SIGSTEP (next step) not the SIGSTOP (close, CTRL+C usually), then read the next intruction, wich is a recursive call to .bat itself. Because you're always into PHP -a mode, no exit command. You must use CTRL+C or hit the exit cross with mouse. (No alt+f4)
You can also use "Bat to Exe" converter to easy use.
That is because you are in 'Interactive Mode' where php evaluates everything you type. To see the end result, you do 'ctrl+z' and Enter. You should see the evaluated result now :)
p.s. run the cmd as Administrator!
The following solution is specifically for wamp environments:
This foxed me for a little while, tried all the other suggestions, $PATH etc even searched the windows registry looking for clues:
The GUI (wampmanager) indicates I have version 7 selected and yes if I phpinfo() in a page in the browser it will tell me its version 7.x.x yet php -v in the command prompt reports a 5.x.x
If you right click on the wampmanager head to icon->tools->delete unused versions and remove the old version, let it restart the services then the command prompt will return a 7.x.x
This solution means you no longer have the old version if you want to switch between php versions but there is a configuration file in C:\wamp64\wampmanager.conf which appears to specify the version to use with CLI (the parameter is called phpCliVersion). I changed it, restarted the server ... thought I had solved it but no effect perhaps I was a little impatient so I have a feeling there may be some mileage in that.
Hope that helps someone
just do these steps if you don't need your old php version:
- open wamp and right click on wamp manager than go : tools/Change PHP CLI Version than change php version to latest
- another time right click on wamp manager than go : tools/Delete unuserd versions and delete the oldest version which your system insist on it to be your pc php version :D
- go to control panel/user account/change my environment variables and in PATH variable click edit and add your latest php version path which is in your wamp server bin folder
- close all command lines or IDEs and restart them and check for php -v
this works well
In windows, put your php.exe file in windows/system32 or any other system executable folders and then go to command line and type php and hit enter following it, if it doesnt generate any error then you are ready to use PHP on command line. If you have set your php.exe somewhere else than default system folders then you need to set the path of it in the environment variables! You can get there in following path....
control panel -> System -> Edith the environment variables of your account -> Environment Vaiables -> path -> edit then set the absolute path of your php.exe there and follow the same procedure as in first paragraph, if nothing in the error department, then you are ready to use php from command line!
A slight improvement on RiggsFolly's script above, if you set:
and add your new PHP ver path at the beginning; this allows you to set a default path in your Environment setting and then you only need this script when you want to change to a different version.
Also, if like me, you want to run this in a git bash shell, just call make a bash script to call the .bat file:
eval phppath.bat $1
