php exec无法在Mamp上工作

Question

I'm trying to launch an executable myapp made with unity by using the following code in php, but I'm getting errors.

<?php
echo "yo";
echo exec('whoami',$output,$retval);
echo $retval;
echo exec('myapp.app',$output,$retval);
echo $retval;
echo exec('/Applications/MAMP/htdocs/myapp.app/',$output,$retval);
echo $retval;
?>

The result is yodan127127. 127 I looked up in error codes means procedure not found.

I have also commented out some lines in Applications/Mamp/Library/bin/envvars_ which was recommended in other posts.

I have put the myapp.app in several directories htdocs,bin,cgi-bin, but gives the same error.

#if test "x$DYLD_LIBRARY_PATH" != "x" ; then
#  DYLD_LIBRARY_PATH="/Applications/MAMP/Library/lib:$DYLD_LIBRARY_PATH"
#else
#  DYLD_LIBRARY_PATH="/Applications/MAMP/Library/lib"
#fi
#export DYLD_LIBRARY_PATH
#

You have to point exec to the binary, and not the container for it.

The .app is just a container directory that has an internal structure, the binary is somewhere in a path that should look like /Applications/MAMP/htdocs/myapp.app/Contents/MacOS/myapp . The precise location of the binary is in the /Applications/MAMP/htdocs/myapp.app/info.plist file. You can right click on the app and select show package contents to view the structure.

But the easiest way to run the app is to open it with the open command:

open '/Applications/MAMP/htdocs/myapp.app/'

It should be runnable from php as an argument to exec .

Excel推荐用于PHP，因此需要在服务器上安装，推荐像image magick等。然后使用exec（）函数。
