cygwin: can't execute PHP script via PATH - php

I have written a PHP script "toalpha" (purpose not relevant to this question). The script is in $HOME/bin. If my CWD is $HOME/bin, I can execute it by typing "./toalpha". But if I simply type "toalpha", I get a message:
Could not open input file: /c/barry/bin/toalpha
Some information that may be relevant:
. I recently upgraded my desktop from WinXP to Win7.
. This is the first time that I have made my own userid be an ordinary user instead of an admin. (I tried to do that on XP, but ran into problems and went back to having my normal userid be the admin. Don't need a solution for that because I'm no longer running XP and besides it was my own fault.)
. My $HOME is /c/barry
I did that by adding the following to the .bashrc created when I installed cygwin:
mount C: /c
HOME=/c/barry
cd
. .bashrc
. The first two lines of the PHP script are:
#!/c/xampp/php/php
<?php
. Yes, the copy of PHP I want to use is in C:\xampp\php\php.exe
. I have another, similar script that I wrote on WinXP. It starts with the same two lines. It worked fine under XP, but doesn't work on Win7.
My best guesses at the source of the problem:
A difference between XP and Win7
I fumbled the home directory change in some way. IIRC, when I installed cygwin on XP I did some trickery so it would start directly in C:\barry but I couldn't remember how I did that when I installed it on Win7, so I took the "easy way out".

bash is passing to "C:\xampp\php\php.exe"
the file name "/c/barry/bin/toalpha"
but that is a cygwin path and your PHP does not regognize it.
You should convert it in an understandable one using
cygpath
Try
/c/xampp/php/php $(cygpath -w /c/barry/bin/toalpha )

Laravel and Mamp Localhost Error 500 Mac

So after a fresh install of laravel (v5.4) and using Mamp as my local server I just get (in chrome)
The localhost page isn’t working
localhost is currently unable to handle this request.
HTTP ERROR 500
I've tried countless things like changing permissions on storage or everything within the laravel directory.
Done composer update/install in the directory.
I'm running PHP v7.0.12 on my Mac (10.11.6). Cant think of anything else that would be causing this?
If I create another directory which a simple index.php with '' it loads absolutely fine so what is causing an issue with laravel?
Here's pics of my mamp setup
http://i.imgur.com/xT3mMZO.png
http://i.imgur.com/ddz9uij.png
Open up terminal and type:
tail -n 20 /Applications/MAMP/logs/php_error.log
This may give you some clue as to what is going on.
Hope this helps, happy coding :)
I just joined stackoverflow yesterday so I do not have enough reputation to comment. I write an answer here.
here is the short answer:
run :
PHP_VERSION=`ls /Applications/MAMP/bin/php/ | sort -n | tail -1`
echo "export PATH=/Applications/MAMP/bin/php/${PHP_VERSION}/bin:$PATH" >> .bash_profile
source ~/.bash_profile
check your php version by running php -v. close the terminal. Open another terminal and check php version again.if you see php 5 again then there are 2 possibilities:
First: you added the /path/to/php7 after /path/to/php5 and php 5 is loaded first.
Second: system loads another bash file first which your php 5 path is mentioned in it. I know that this sounds confusing having several bash file but it is. Please search for other files like bashrc or similars.
This is the long answer for anyone else:
first of all, if you are on mac, I highly suggest you to use valet to get rid of all these things.
But regarding the problem:
As you already noted that it is not a laravel issue. the php version that your machine uses is under the min required version by laravel. You have 2 versions of php at the moment. MacOs is shipped with php installed on that. I think it is the same php 5.5.36 that is making problem for you. Since Laravel 5.4, you need to use PHP >= 5.6.4.
Although you have installed parallel php 7 on your machine, you need also to check which php your machine is reading from by running which php. after that remember to add your path to php 7 installed to bash_profile or other bash files on your mac(you can have 4 or 5 bash files).
Considering you have only one bash file named as bash_profile and you are going to export the path to your php 7 to bash profile, If you run following command, that appends the path to the end of file
PHP_VERSION=`ls /Applications/MAMP/bin/php/ | sort -n | tail -1`
echo "export PATH=/Applications/MAMP/bin/php/${PHP_VERSION}/bin:$PATH" >> .bash_profile
remember to use source ~/.bash_profile in order to make changes effected.
Alternatively you can open the bash_profile file in your text editor by running:
open -a /Applications/TextEdit.app ~/.bash_profile
and add the path manually before the /path/to/php5 path.
finally you must check your php version by running php -v.
close the terminal. Open another terminal and check php version again. If you see php 7 then you are all fine. But if you see php 5 again then there are 2 possibilities:
First: you added the /path/to/php7 after /path/to/php5 and php 5 is loaded first.
Second: system loads another bash file first which your php 5 path is mentioned in it. I know that this sounds confusing having several bash file but it is. Please search for other files like bashrc or similars.

Run PHP script in background on Apache start/restart(Windows Server)

I've installed Apache 2.4 with PHP 5.4 on Windows Server 2008 following instructions from this manual:
Apache installing manual.
Apache runs as a service now.
My application requires a php websocket script to run in the background. I'm running it manually with:
php myscript.php
The question is: Is there a way to start a background script automatically on system(apache) restart?
I found the following topic, but I didn't know where I could find an apache startup script for Windows.
Any help will be much appriciated.
I come up with a solution :)
Create an environment variable pointing to your Apache directory
APACHE_HOME = C:/PATH/TO_APACHE
Rename %APACHE_HOME%\bin\httpd.exe to %APACHE_HOME%\bin\httpdVendor.exe
Create a batch file and put the following code :
php myscript.php
%APACHE_HOME%\bin\httpdVendor.exe -k runservice
exit 0
Download/Install the free software BatToExeConverter (next, next, ...)
Open the installed converter and open your freshly created batch file
Click on the button Build EXE (let the default configuration)
Save the file : %APACHE_HOME%\bin\httpd.exe
Start your Apache Server
Tested on : Windows 7, Apache 2.4, Advanced Bat to Exe Converter 2.92
Use built in Windows Task Scheduler which triggers .bat script, which calls curl with defined url.
Download curl from http://curl.haxx.se/download.html and extract curl.exe on any directory, but we will use c:\backgroundtasks
Adjust script below to your needs:
cd c:\
cd c:\backgroundtasks
curl http://localhost/path/to/script.php
exit
Configure Task Scheduler to run as basic task:
General tab - as system account (to run when you are not logged in server)
Triggers tab - adjust frequency
Settings tab - at bottom set If the task is already running... to Stop the existing instance
The best method here would be to use Windows services dependencies.
Make a php-websocket-server.cmd file with any necessary environment settings (e.g. changing to a directory, setting PATH, etc...) with the last line:
php myscript.php
Install the Windows Server Resource Kit Tools, to get srvany and instsrv to create a user defined service. Note the install path as you'll need it in the next step.
Open a cmd shell and run:
<path_to_resource_kit>\instsrv PHPWebSocketServer <path_to_resource_kit>\srvany.exe
Next, create a file php-websocket-server.reg containing the following (update for your environment):
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PHPWebSocketServer\Parameters]
"Application"="c:\\path\\to\\php-websocket-server.cmd"
Import it by double-clicking or regedit /s php-websocket-server.reg
Back in your cmd shell:
sc config Apache2.4 depend= PHPWebSocketServer
to make the Apache2.4* service depend on your php service. Now, when Apache is started, the php service will be brought up first. And likewise, if you stop the php service Apache will stop along with it.
*the howto indicates that the service is named "Apache2.4" but you may want to verify in your installation.
When running as service, you won't have the startup script.
Execute some service implementation that allows running other programs as services, and then make the new service (which is running your script) a dependency of the Apache service. However, this will not restart the script when apache restarts.
One possible solution using SrvStart, and another using ServiceEx.
Perhaps don't install Apache as a service, and then edit the startup/restart script, and use the above method to run Apache as service (instead of using Apache's own installer).
Create bat file,e eg 'myphp.bat' containing path/php myscript.php. Include the correct path to php if it's not path'd.
create a bat file, eg runmyphp.bat containing
AT 00:00 /every:M,T,W,Th,F "cmd /c /path/myphp.bat", again including the correct path.
Then use explorer to drag runmyphp into the startup folder, so it will always run on system startup.
Google 'windows at command' or 'windows cron' to get all the correct syntax for the 'at' command, but you can currently find a detailed explanation here.
I found another answer C:\wamp\scripts\wampserver.lib.php this file is run every time when your wamp starts
include your file path include_once("file_path"); to this file and its done . this is perfect solution which you want
Enjoy!!!!!!!!!
Although the solution of Halayem Anis is very creative, I think its important to note that you can never be sure that a PHP script keeps running in the background. So if you choose to start your script on "Apache start", then you probably end op resetting Apache quite often, simple to reboot your script.
I assume that's even how you came to this question, as on a normal server you never have to touch the Apache reset button. It starts on system start and then it just runs. If that was the case, you could simple run your php myscript.php command on start up.
Considering there is no way to make sure the script keeps running, I would use a different approach, where I check if it is running and if not, restart it.
So the first step is to make it possible to track if the script is running. I would go for the simple approach where your myscript.php writes a single byte to a file every 5seconds or so. This way I can use the last modified time on the file to see if it is still running, because last modified time + 5 seconds < now == not running.
You could also store the last access time in a database every 5 seconds or so. Might be slightly faster then accessing files if you have a lot of traffic.
The second part is to have each request check if the script is running. For this two work I would use the PHP.ini to prepend a php script on every request. You can do it with the auto_append_file option.
This prepend script would work like this:
<?php
$filename = 'checkonline.txt';
$cmd = "php myscript.php";
if (filemtime($filename)+5<time()) {
//run in background without freezing php
//based on code posted on PHP exec manual, linked below
if (substr(php_uname(), 0, 7) == "Windows"){
pclose(popen("start /B ". $cmd, "r"));
}
else {
exec($cmd . " > /dev/null &");
}
}
?>
Make sure to check how filemtime and exec work and what you need to keep in mind. They work slightly different on Windows/*nix.
Wrap-up all your required processes in a batch file and use RunAsService
With some tweaking, you can ensure that your service starts before Apache.

How to determine path to php.exe on Windows - search default paths

I'm currently developing a couple of plugins for Sublime Text 2 on OS X and I would like to make them cross platform, meaning I have to find out if and where php.exe is installed.
Right now I call /usr/bin/php in Python, which obviously works only on OS X and Linux:
phppath = '/usr/bin/php'<br>
pluginpath = sublime.packages_path() + '/HtmlTidy/tidy.php'<br>
retval = os.system( '%s "%s"' % ( phppath, scriptpath ) )
But on Windows, there seems to be no definitive default path for php.exe. The more I googled for it, the more possibilities showed up. So far I think I would have to check each of the following paths for existence:
c:\php\php.exe
c:\php5\php.exe
c:\windows\php.exe
c:\program files\php\php.exe
c:\wamp\bin\php\php5\php.exe
c:\xampp\php\php.exe
That's already quite a collection, but what I'm asking for is either a complete list covering all possibilities - or another way to figure it out that should be as robust as checking each possible path.
So if you have php.exe installed in some place other than these, please leave a comment with your path and I will add it to the list above.
Besides, there seems to be php.exe and php-cli.exe. I guess it would be OK to loop through each possible path. Check first for php-cli.exe, check for php.exe, and take the first match. Is that correct or is there a better practice?
If the user has added PHP's bin folder to the system PATH, then you should just be able to try and execute php -v to check that it's present.
If you want to obtain the full path to the PHP executable and the target system is Windows Server 2003 or later (so Windows Vista, and Windows 7) then you could use the WHERE command, i.e.:
C:\> where php.exe
C:\Program Files (x86)\WAMP\bin\php\php5.3.5\php.exe
Also see possibly related question: Is there an equivalent of 'which' on the Windows command line?.
If you are really desperate to find any file on the user's computer, you could try executing the equivalent of a find - but it's going to be slooow!
C: && cd \ && dir /s /b php.exe
On powershell or commad prompt
php -r "echo PHP_VERSION;" gives the version
See other PHP constantas:
https://www.php.net/manual/es/reserved.constants.php
to answer your question
php -r "echo PHP_BINARY;" gives the full path to php.exe
if needed, to remove the php.exe
php -r "echo str_replace('php.exe', '', PHP_BINARY);"
From PHP 5.4 and later, you can use the PHP_BINARY constant.
Use:
C:\xampp\php\php.exe
It should work if your XAMPP instance is on D: or E:. You change it accordingly from C:.
I found a way for you to find out where the php.exe is stored. In C:, click the search bar and search for "php.exe". Then, there will appear an application called php and click it. Then, cmd will open and in the cmd tab it will say php.exe at the end. That's where your php.exe is and you can put the link address of the file in VS Code.
Try
echo PHP_BINDIR;
It works. I tested it on macOS as with PHP 5.6.

Warning: exec(): Unable to fork in PHP

I'm using php 5 apache on windows server 2008, I have disabled IIS.
I m using exec command in my PHP script and it was working fine
but today I got an error:
Warning: exec(): Unable to fork
I gave permissions to cmd.exe in C:\Windows\System32 folder
but this did not fix the problem.
Specifically which permissions did you give to who?
Probably not to the right user..
Run this php script:
echo 'Script is executed by: ' . get_current_user() . getmygid();
It will tell you which user is running the PHP scripts and therefore which user to grant permissions to cmd.exe.
In 64-bit windows (e.g server 2008), theres a folder named c:\windows\syswow64, that contains all executables/dll, that are required by a 32 bit app. installed on your 64-bit machine.
Make sure your required 32-bit .exe/dll etc is placed in that folder.
if you cant find it there you will have to put a 32-bit version of the required .exe/dll
there.So this can used by yopur app/process.
Now when your 32-bit application/process executes, windows will automatically redirect your process to execute required app in syswow64 folder.
Hopefully that should resolve your compatibility issue.
I had this problem myself, but was eventually able to resolve it. The problem was due to how I had accidentally set cmd.exe to "Run as Administrator" by default. I say "accidentally" as I thought I was only setting the compatibility settings of a shortcut on my task bar, but it turned-out it was setting the compatibility of the .exe itself. Anyhow, I disabled this by deleting the registry key here:
HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers
After doing this, everything started working again.

Accessing kd Debugger via php

I work at a small computer shop, and we have to analyze windows minidumps all the time. My idea was to install the Windows Debugging Tools on a windows PC and use apache/PHP as an interface to it. That way I could just set up an HTML upload form that would accept the minidump file, run it through KD, then spit out the output.
It nearly works. I created a special user just for apache so I could assign it write privaleges to C:\symbols, and I use the following code:
<?php
$kdScript = "\"\\Program Files\\Debugging Tools for Windows (x86)\\kd.exe\" -c \"!analyze -v;Q\" -y srv*c:\symbols*http://msdl.microsoft.com/download/symbols -z ";
$kdScript .= $_FILES["myFile"]["tmp_name"];
$output = `$kdScript`;
print("<pre>$output</pre>");
?>
The problem I'm having is that the symbols are not downloaded as they should be. I've verified apache is running as the user I think it is by calling "whoami" from inside backticks. I've verified that I can run the windows version of wget from within backticks, so I have access to the network. I can file_put_contents() into a new file under C:\symbols, so I have file creation permissions.
Also, I tried having PHP simply output the command to the browser so I could copy and paste it into a terminal. I was able to run a command prompt as my apache user via "runas", paste the command from PHP's output into the prompt, and it worked as expected, downloading all the symbols it needed to C:\symbols. Of course, I had to point it to a dump file NOT in the PHP temp directory, but this shouldn't make a difference.
What could be the problem? Just as a side note, all of this is local on a trusted pc in a company that has a total of 3 employees/owners. Security for this project is irrelavent.
Not sure what your exact problem is, but the symbol server client code is finicky and not very debuggable, it took us lots of tinkering to implement our version of this. You can always direct folks there or use it yourself:
