什么是命令行和EXEC()与PHP运行脚本之间的区别? [英] What is the difference between running a script from the command line and from exec() with PHP?
问题描述
我想运行一个Python脚本执行exec()在PHP。我的命令工作正常,当我运行它,直接使用 CMD
窗口,但它产生的时候,我从运行EXEC()的错误
在PHP。
我的Python脚本使用 NTLK 找到专有名词。示例命令:
C:\\ Python25 \\ python.exeC:\\ WAMP \\项目\\ python的\\干线\\试验\\ find_proper_nouns.py我今天早上去了伦敦
收益 [伦敦]
当我从 CMD
运行,但投在Apache的错误日志,当我请从相同的命令执行exec()
.The脚本defintely越来越运行正常 - 如果我改变了python脚本是打印的Hello World
时返回正常。
我知道这是一个很大的要求,任何人知道如何解决这个NLTK错误,但是我真的可以做任何指针,为什么从 EXEC运行它
是不同的到 CMD
。 (该命令是相同的)。
我在Windows 7上运行WAMP与Apache 2.2.11。
下面是在Apache日志中的错误:

I'm trying to run a Python script using exec() from within PHP. My command works fine when I run it directly using a cmd
window, but it produces an error when I run it from exec()
in PHP.
My Python script uses NTLK to find proper nouns. Example command:
"C:\Python25\python.exe" "C:\wamp\projects\python\trunk\tests\find_proper_nouns.py" "I went to London this morning"
returns [London]
when I run it from cmd
, but throws an error in the Apache log when I run the same command from exec()
.The script is defintely getting run OK - if I change the python script to be print "Hello World"
that is returned fine.
I know it's a big ask for anyone to know how to fix this NLTK error, but I could really do with any pointers as to why running it from exec
is different to cmd
. (The command is identical).
I'm running WAMP on Windows 7 with Apache 2.2.11.
Here's the error in the Apache log:
Traceback (most recent call last):

parts = nltk.pos_tag(text)

Your web server likely runs with other privileges than yourself. Possible problems include:
- Path/file permission: can the web server user access the files it needs?
- Different environment: are all necessary environment variables (PATH, Python-specific stuff, …) set?
- Configuration: are there per-user configurations for Python or the module?
Tip: execute set in both the command prompt and from the PHP process and check the differences.
