已解决：安装 Homebrew ImageMagick 后，MAMP Php 无法执行（“转换”）
我在 Lion 上使用 Homebrew 安装了 Imagemagick，一切都很好，只是从 php 调用时它根本不起作用。控制台：
$ convert -version
Version: ImageMagick 6.7.1-1 2011-07-29 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2011 ImageMagick Studio LLC
Features: OpenMP
$ which convert
/usr/local/bin/convert
PHP：
echo exec ('convert -version');
或 exec('转换-版本', $output); var_dump($输出);
不产生任何内容（或产生空数组）。
exec ('/usr/local/bin/convert') // works, but
exec ('which convert') // doesn't
我需要在本地进行测试，以确保我可以在生产环境中检测到转换。但我无法正确测试它。 PATH 已设置并且可以在终端中使用，但不能在 PHP 中使用。
已解决：
事实证明，要使 php 正常工作，convert 应该位于 /usr/bin/ 中，所以这解决了它：
ln -s /usr/local/bin/convert /usr/bin/convert
更新
这是因为MAMP，这里是修复：http://firedevcom.tumblr.com/post/22791937644/fix-for-homebrew-imagemagick-and-mamp
打开 /Applications/MAMP/Library/bin/envvars
并注释掉以下几行：
DYLD_LIBRARY_PATH="/Applications/MAMP/Library/lib:$DYLD_LIBRARY_PATH"
export DYLD_LIBRARY_PATH
完成。
I installed Imagemagick using Homebrew on Lion, everything is fine except that it doesn't work at all when being called from php. Console:
$ convert -version
Version: ImageMagick 6.7.1-1 2011-07-29 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2011 ImageMagick Studio LLC

$ which convert
/usr/local/bin/convert
PHP:
echo exec ('convert -version');
or
exec('convert -version', $output);
var_dump($output);
Produces nothing (or an empty array).
exec ('/usr/local/bin/convert') // works, but
exec ('which convert') // doesn't
I need to test this locally to make sure I can detect convert in production environment. But I can't properly test it. The PATH is set and it works in Terminal, but not from PHP.
Resolved:
Turns out, for php to work convert should be in /usr/bin/ so this solved it:
ln -s /usr/local/bin/convert /usr/bin/convert
Update
It was becasue of MAMP, here is the fix: http://firedevcom.tumblr.com/post/22791937644/fix-for-homebrew-imagemagick-and-mamp
Open /Applications/MAMP/Library/bin/envvars
And comment out the following lines:
DYLD_LIBRARY_PATH="/Applications/MAMP/Library/lib:$DYLD_LIBRARY_PATH"
export DYLD_LIBRARY_PATH
Done.

Adding my own answer here so you can vote:

验证convert in 是服务器的PATH 环境变量。或者只指定完整路径：
Verify that convert in is the server's PATH environment variable. Or just specify the full path:
exec返回命令结果的最后一行，该行恰好是一个空字符串。如果你想获得输出，只需执行以下操作：
The
execreturns the last line from the result of the command which happens to be an empty string.If you want to get the output, just do something like this:
只需使用
exec("PATH=\$PATH:/usr/local/bin; Convert file.pdf file.png");它会在运行时将 Convert 添加到 PATH 。Simply use
exec("PATH=\$PATH:/usr/local/bin; convert file.pdf file.png");It will add convert to PATH on runtime.而不仅仅是 exec("convert .... ");
使用完整路径。你可以通过在终端输入来获取它
你应该得到类似的东西：
转换是散列的（/opt/local/bin/convert），
所以现在使用：

在评论之后
在 /Applications/MAMP/Library/bin/envvars 中
instead of just exec("convert .... ");
use a full path. you can get it by typing the terminal
you should get something like:
convert is hashed (/opt/local/bin/convert)
so now use:

after that comment out
in /Applications/MAMP/Library/bin/envvars
