Depending on what you are doing, <a href="http://php.net/manual/en/function.system.php" rel="noreferrer">system()</a> or <a href="http://php.net/manual/en/function.popen.php" rel="noreferrer">popen()</a> may be perfect. Use system() if the Python script has no output, or if you want the Python script's output to go directly to the browser. Use popen() if you want to write data to the Python script's standard input, or read data from the Python script's standard output in php. popen() will only let you read or write, but not both. If you want both, check out <a href="http://us.php.net/manual/en/function.proc-open.php" rel="noreferrer">proc_open()</a>, but with two way communication between programs you need to be careful to avoid deadlocks, where each program is waiting for the other to do something.

If you want to pass user supplied data to the Python script, then the big thing to be careful about is command injection. If you aren't careful, your user could send you data like "; evilcommand ;" and make your program execute arbitrary commands against your will.

<a href="http://www.php.net/manual/en/function.escapeshellarg.php" rel="noreferrer">escapeshellarg()</a> and <a href="http://www.php.net/manual/en/function.escapeshellcmd.php" rel="noreferrer">escapeshellcmd()</a> can help with this, but personally I like to remove everything that isn't a known good character, using something like

<pre><code>preg_replace('/[^a-zA-Z0-9]/', '', $str)

You can run a python script via php, and outputs on browser.

Basically you have to call the python script this way:

<pre><code>$command = "python /path/to/python_script.py 2&gt;&amp;1";
$pid = popen( $command,"r");
while( !feof( $pid ) )
{
 echo fread($pid, 256);
 flush();
 ob_flush();
 usleep(100000);
}
pclose($pid);
</code></pre>

Note: if you run any time.sleep() in you python code, it will not outputs the results on browser.

blocks|key|1729498|text|我一直在做这样的事情，为了快速和肮脏的脚本。CGI或PHP脚本仅仅使用system/popen来调用一些外部程序是很常见的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1729499|只要格外小心，如果你的网络服务器是开放给互联网的。在这种情况下，一定要清理GET/POST输入，以免攻击者在您的机器上运行任意命令。|1729500|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I do this kind of thing all the time for quick-and-dirty scripts. It's quite common to have a CGI or PHP script that just uses system/popen to call some external program.

Just be extra careful if your web server is open to the internet at large. Be sure to sanitize your GET/POST input in this case so as to not allow attackers to run arbitrary commands on your machine.

blocks|key|1729812|text|您的call_python_file.php应该如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1729813|<?php
++++$item='Everything+is+awesome!!';

++++echo+$tmp;
?>|code-block|syntax|javascript|1729814|这将执行python脚本并将结果输出到浏览器。而在python脚本中，(sys.argv1:)变量将引入所有参数。为了将argv作为字符串显示在php所在的位置，所以如果你想创建一个文本区：|1729815|import+sys

list1+=+'+'.join(sys.argv[1:])

def+main():
++print+list1

Your call_python_file.php should look like this:

<pre><code>&lt;?php
 $item='Everything is awesome!!';
 $tmp = exec("py.py $item");
 echo $tmp;
?&gt;
</code></pre>

This executes the python script and outputs the result to the browser.
While in your python script the (sys.argv[1:]) variable will bring in all your arguments. To display the argv as a string for wherever your php is pulling from so if you want to do a text area:

<pre><code>import sys

list1 = ' '.join(sys.argv[1:])

def main():
 print list1

if __name__ == '__main__':
 main()
</code></pre>

blocks|key|1514726|text|请注意，如果您使用的是虚拟环境(如在共享主机中)，则必须将路径调整为python，例如：/home/user/mypython/bin/python+./cgi-bin/test.py|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1514727|entityMap^0|18|1C|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

is so easy 
You can use [phpy - library for php][1]
php file
<pre><code>&lt;?php
 require_once &quot;vendor/autoload.php&quot;;

 use app\core\App;

 $app = new App();
 $python = $app-&gt;python;
 $output = $python-&gt;set(your python path)-&gt;send(data..)-&gt;gen();
 var_dump($ouput);
</code></pre>
python file:
<pre><code>import include.library.phpy as phpy
print(phpy.get_data(number of data , first = 1 , two =2 ...))
</code></pre>

I have a Python script I recently wrote that I call using the command line with some options. I now want a very thin web interface to call this script locally on my Mac.

I don't want to go through the minor trouble of installing mod_python or mod_wsgi on my Mac, so I was just going to do a system() or popen() from PHP to call the Python script.

Any better ideas? Thanks in advance!

Calling Python in PHP

我有一个最近编写的Python脚本，我使用带一些选项的命令行来调用它。我现在想要一个非常薄的web界面，以便在我的Mac上本地调用此脚本。我不想经历在我的Mac上安装mod_python或mod_wsgi的小麻烦，所以我只想在PHP中执行一个system()或popen()来调用Python脚本。有更好的主意吗？提前感谢！
