I have a php script (lets call this /test.php) on my server. After Grunt automatically has parsed my SCSS and JS I would like to run this test.php script (it resets my memcache). I can't seem to find a way to do this. Anyone got a clue?
You can use grunt-shell to run your php script on cli via php -f your-script.php
grunt.initConfig({
shell: {
php: {
command: 'php -f your-script.php'
}
}
}
grunt.registerTask('runTestPhp', ['shell:php']);
If you don't want to run your php script through cli, have a look at grunt-php.

I'm running a php socket. I run the program through nohup. Run this program properly through root. But my problem is running the program via the exec () function in php. When I run the command this way the program runs correctly but the program output is not printed in nohup.out.
my command in ssh:
nohup php my_path/example.php & #is working
my command in user php:
exec('nohup php my_path/example.php >/dev/null 2>&1 &', $output); #not update nohup.out
please guide me...
From PHP docs on exec:
If a program is started with this function, in order for it to continue running in the background, the output of the program must be redirected to a file or another output stream. Failing to do so will cause PHP to hang until the execution of the program ends.
From man nohup:
If standard input is a terminal, redirect it from /dev/null. If standard output is a terminal, append output to 'nohup.out' if possible, '$HOME/nohup.out' otherwise. If standard error is a terminal, redirect it to standard output. To save output to FILE, use 'nohup COMMAND > FILE'.
To satisfy both - redirect manually to nohup.out:
exec('nohup php my_path/example.php >>nohup.out 2>&1 &', $output);
Is there a way, from a bash script and/or a terminal, to run php interactively and load in a predefined file at the same time?
Essentially, I want to do the following two steps in a single step:
shell# php -a
Interactive mode enabled
php > require_once('ABSOLUTE_PATH_TO_FILE');
I tried using php -a --file='ABSOLUTE_PATH_TO_FILE' but the functions I want to load do not become available in interactive mode.
If you have a test.php file with this contents
<?php
function asd() {
echo "Hi!";
}
?>
You must use:
php -a -d auto_prepend_file=test.php
I have a series of shell commands I want to put in a program and execute the program from the command line. I decided to use PHP for this so currently I am trying to get the most basic shell commands to run.
Save as build.php
<?php
shell_exec('cd ..');
echo "php executed\n";
?>
From the command-line
php build.php
Output
php executed
Php executes correctly but I'm still in the same directory. How do I get shell_exec( ... ) to successfully call a shell command?
You need to change the cwd (current working directory) in PHP... any cd command you execute via exec() and its sister functions will affect ONLY the shell that the exec() call invokes, and anything you do in the shell.
<?php
$olddir = getcwd();
chdir('/path/to/new/dir'); //change to new dir
exec('somecommand');
will execute somecommand in /path/to/new/dir. If you do
<?php
exec('cd /path/to/new/dir');
exec('somecommand');
somecommand will be executed in whatever directory you started the PHP script from - the cd you exec'd just one line ago will have ceased to exist and is essentially a null operation.
Note that if you did something like:
<?php
exec('cd /path/to/new/dir ; somecommand');
then your command WOULD be executed in that directory... but again, once that shell exits, the directory change ceases to exist.
How we run php script using Linux bash?
php file test.php
test.php contains:
<?php echo "hello\n" ?>
From the command line, enter this:
php -f filename.php
Make sure that filename.php both includes and executes the function you want to test. Anything you echo out will appear in the console, including errors.
Be wary that often the php.ini for Apache PHP is different from CLI PHP (command line interface).
Reference: https://secure.php.net/manual/en/features.commandline.usage.php
First of all check to see if your PHP installation supports CLI. Type: php -v. You can execute PHP from the command line in 2 ways:
php yourfile.php
php -r 'print("Hello world");'
There are two ways you can do this. One is the one already mentioned, i.e.:
php -f filename.php
The second option is making the script executable (chmod +x filename.php) and adding the following line to the top of your .php file:
#!/path/to/php
I'm not sure though if a webserver likes this, so if you also want to use the .php file in a website, that might not be the best idea. Still, if you're just writing some kind of script, it is easier to type ./path/to/phpfile.php than having to type php -f /path/to/phpfile.php every time.
Simply this should do:
php test.php
just run in linux terminal to get phpinfo .
php -r 'phpinfo();'
and to run file like index.php
php -f index.php
php -f test.php
See the manual for full details of running PHP from the command line
php test.php
should do it, or
php -f test.php
to be explicit.
I was in need to decode URL in a Bash script. So I decide to use PHP in this way:
$ cat url-decode.sh
#!/bin/bash
URL='url=https%3a%2f%2f1%2fecp%2f'
/usr/bin/php -r '$arg1 = $argv[1];echo rawurldecode($arg1);' "$URL"
Sample output:
$ ./url-decode.sh
url=https://1/ecp/
Im new to php shell commands so please bear with me. I am trying to run the shell_exec() command on my server. I am trying the below php code:
$output = shell_exec('tesseract picture.tif text_file -l eng');
echo "done";
I have the picture.tif in the same directory as the php file. In my shell I can run this without a problem.
It takes a while to run the code, then it doesnt make the text_file like it does when I run it in command prompt.
Per your comment:
Should I write a loop in shell
instead?
You can write a very simple shell script to run the command in a loop. Create the script file first:
touch myscript.sh
Make the script executable:
chmod 700 myscript.sh
Then open it with a text editor such as vim and add this:
for (( i = 0 ; i <= 5; i++ ))
do
tesseract picture.tif text_file -l eng
done
Thats the very basics of it (not sure what else you need), but that syntax should help get you started. To run the script, do this if you're in the same directory as the script:
./myscript.sh
Or specify the full path to run it from anywhere:
/path/to/mydir/myscript.sh
Could this be a permissions issue? My guess is that PHP isn't running with the same permissions that you do when you execute the command directly from the command prompt. What OS are you running on?
