I have a Python script that is using MySQLdb on OSX Lion. To get MySQLdb to work, I had to add
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH
to my ~/.bash_profile. The python script, when executed from the command line, works just fine.
When I try executing the same python script from a PHP script using the exec() function, the python script is unable to locate the library path. Here's the err msg from the Apache log:
ImportError: dlopen(/Library/Python/2.7/site-packages/_mysql.so, 2): Library not loaded: libmysqlclient.18.dylib
Referenced from: /Library/Python/2.7/site-packages/_mysql.so
Reason: image not found
I'm assuming this is a user issue though I'm unclear on how to fix it.
Where should I put this path so that it will be globally available to all scripts and users on my machine? (well at least, to Apache and Root)
Solution: creating a soft link did the trick:
sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib
This solution was taken from comments on this post. Perhaps this solution will help another struggling with MySQLdb on OSX.
Though I'm still not clear on why it worked on one user and not another - or, rather, to which file the above mentioned export should have been saved in order to make it available to all. Any explanation on this would be appreciated.
It looks like you need to modify sys.path array. It initialized from the environment variable PYTHONPATH: http://docs.python.org/library/sys.html#sys.path
For Apache you can add PYTHONPATH entry to the EnvironmentVariables section in /System/Library/LaunchDaemons/org.apache.httpd.plist that will make it available to anything Apache runs. See man launchd.plist for details.
For root you can add an export PYTHONPATH to /etc/profile which will make it available to all sh and bash login shells. See man bash for details.

I've been trying and searching about a small issue I have in our php application. We use a which to find the full path of a program, however it returns with
which: no bla in ((null))
on Centos, on our own debian boxes it works just fine. I've figured out since then that (obviously) the PATH is not available in the shell from PHP. But what I can't find out is why that is the case. I've replaced the command with all sorts of commands to find out what the environment is in which I run in.
If I run an echo $PATH I actually see the directories I've set in the .bash_profile. If I run echo $SHELL I know I am using bash, if I run whoami I found out I am not the apache user but a different user, whom I changed the .bash_profile for. As I've read there's a difference between shells, so I thought it might not load the .bash_profile so I've also added the export PATH to the .bashrc.
I can get it to work with a change in the code, I could replace the which, but I am just genuinely interested in why this is not working on this centos configuration. I've now added an export PATH in the exec function before the which and it works, and should also work on other systems, but still I think it shouldn't be necessary.
Anyone know what could cause this behaviour?
I am sorry if this question was answered.
Why can't I run php code directly without using terminal on mac.What I mean when you double click on html file it automatically opens in the browser but not in the case of php.If I try to double click on php it opens with some text-editor.
Any help would be helpful.
Try this (for mac),
Open terminal
cd to folder
Start php server - php -S 127.0.0.1:8000
Open browser and enter - http://localhost:8000/file-name.php
I think you don't understand what PHP is ...
HTML is a markup-language, that can directly be understood by the browser. If the browser opens the file, it can do something with the content.
As PHP is a programming-language, you need a parser. This parser is your PHP executable. This program can understand PHP and does nothing more, than running the code and giving something as result. This result may be an HTML webpage, an image or whatever.
Since you said, you're using a mac, here's a quick introduction on how to set up your personal webserver:
On Mac OSX, PHP and Apache (that's what I use in this example) is already installed and pre-configured. You can just start using it like this:
Go into your system preferences and verify that Web Sharing is enabled.
Open the Finder and go to /Library/WebServer/Documents/localhost. All files that are in there are processed by the local webserver (Apache and PHP, if you want to know that). Place your file in there and open your webserver and call http://localhost/YourFile.php and it will call the file YourFile.php and show you what the output of the script is.
EDIT:
If you are using PHP for scripts, like bash-scripts, see the answer #andreas-baumgart provided.
To run PHP in MAC, one should start the built-in Apache Web server and also enable the PHP already installed.
This can be done with the following steps.
Go to /etc/apache2/httpd.conf and change the permission to sudo chmod 777 httpd.conf
Then open the above file to uncomment the line #LoadModule php5_module libexec/apache2/libphp5.so
To start the apache built-in server, use the command sudo apachectl start in the terminal.
Now .php files can be created and run from the terminal using php -f filename.php and it can also be run on a browser using http://localhost/filename.php
You cannot execute plain PHP scripts as they are no executable programs but source code. As such they contain just the receipt for an interpreter to create executable code. In order to run your PHP script you need to pass it to the PHP interpreter. In your scenario you can archive that by providing a shebang.
To run your script on double click try this:
Make the script executable using chmod +x yourscript.php
Prepending the according Shebang to the files content: #!/usr/bin/env php.
Select a PHP file in Finder, hit CMD-i and change "Open With" to "Terminal.app".
Late response, but was looking into doing this for myself, this coming up as one of the results in my searching wanted to provide 2 solutions since I ultimately came to both on my own.
Solution #1
The simple way is to go a round about way by writing a wrapper file to execute the script you're working on. Create a file with the following code:
#!/usr/bin/php
<?php
include('name-of-php-script.php');
?>
Save it as wrapper.command The name wrapper isn't important, but the command extension tells Finder that this is a shell script to open up in Terminal. The file itself just executes whatever php script is in the include.
Solution #2
The specific inquiry requires a bit of work.
First make sure that the 1st line of the php script is:
#!/usr/bin/php
This is where the preinstalled version of PHP is installed on Mac OS X. You can always verify by running this command in terminal:
whereis php
Once you've added the Shebang line to the php script you've readied it for automatic execution.
To make it double clickable executeable you have to do the following:
Right click on the PHP script and click Get Info. Click where it says Open With, click the default option to see all the available options. Select Other...
Switch where it says Enable: from Recommended Applications to All Applications, and click the checkbox for Always Open With. Choose Terminal as the application. Finally, you have to click the button that says Change All...
OS X will verify you want it to set Terminal as the default application to open .php files
This will make every php file open up in terminal by default, but unless they contain the #!/usr/bin/php line they won't actually run.
Try MAMP
MAMP 4 brings even more opportunities for web developers. We are now supporting MySQL 5.6 and Nginx is now fully integrated. Server starting times have been improved.
Because .php files are not 'executable' per se, instead they are just text files with a PHP extension.
You need to run the php interpreter against the file to execute on it's contents.
I'm trying to run this exec
exec('svn export -r '.$rev2.' '.$repourl.'/'.$dir.$parts[$j].' cache/diff/'.$dir.$parts[$j]);
which is equals to:
svn export -r 1192 file:///var/svn/Repo/folder/file.xml cache/diff/folder/file.xml
when i try the script it simply doesn't export the file (the folde is created with another function, so that one is there.)
but if i try to run the svn export as user www-data (from command line) it works.
so i don't get why it should not work from php.. maybe some configuration?
hope someone can help,
thanks in advance
EDIT
Tried also with full path to svn (which svn)
the exec:
exec('/usr/bin/svn export -r '.$rev2.' '.$repourl.'/'.$dir.$parts[$j].'
the result
/usr/bin/svn export -r 1192 file:///var/svn/Repo/folder/file.xml cache/diff/folder/file.xml
Still no changes, the file is not exported.
It is not configuration. Or rather, not directly. Your PHP instance seems to be set to a user which cannot write to the folder you've specified. Either chmod or chown it to something that the user which PHP runs as can write to.
Side note: I wrote a SVN lib for laravel. It is, however, standalone. You might want to ease your burden by using it - it itself uses the PECL SVN extension.
found the solution,
the problem was related to a global variable not letting the exec run.
I have a web accessible PHP script that is using a shell command to drop PDFs to text. I installed Poppler, and am using pdftotext, via MacPorts. I am able to run the command successfully from the CL, and when supplying the full path within the PHP script to '/opt/local/bin/pdftotext'. So, I know that my $PATH is correct and the permissions are sufficient, yet I am still getting an exit status of 127: Command Not Found, when attempting to do simply 'pdftotext' in the exec().
I have tried the answers from How do I add paths to the Apache PATH variable? and http://lists.apple.com/archives/macos-x-server/2008/Sep/msg00433.html. I modified both the /etc/paths and /etc/profile, and added /etc/paths.d/macports all pointing to '/opt/local/bin'. setenv, apache_setenv, etc all had no effect also.
I am using a MAMP (1.9 I think) install for my local development, OSX 10.6, PHP 5.3.5, all a little behind I know :-) ... my $PATH is modified to point to the MAMP bin/php
/etc/paths.d/macports will influence on PATH variable for macports, not for the Apache. You probably need to add /etc/parhs.d/apache (or else) to do what you need.
Edit: also check this and this threads for solutions. It is somewhat outdated but still can help.
As a customer in Plesk, I am attempting to run:
php -q /httpdocs/_external/export/test.php
From this tutorial: http://daipratt.co.uk/crontab-plesk-php/
I'm receiving the error
"php: command not found"
Is there something I need to enable from the main user or a different command I would need to use to run the script?
(also tried /bin/php with no luck, there is no php file in that dir)
"which php"
-/usr/bin/php
(when I use this dir I also get "no such file or dir" I guess since when I use / it's pulling from the customers root not the server root)
This answer will help you. My understanding is that Cron runs everything relative to itself, so you should always use absolute paths when running something from Cron.
Good luck, and happy holidays!
