php script to excute bash script and display results on webpage.

Question

I'm trying to create very simple page that will look up email address in a logfile

I wrote a bash script (with complex awk and sed queries ) that accepts single argument (email address) and it will display the output as follows.

DATE                    email                      phone 
31/1/2013               [email protected]           1800-000-000

how can I go about creating a webpage that will only take an email address and a search button that will simply execute the bash script in the backend and display the output to the screen?

Thank you

 exec ("/path/to/script", $output);

That will output result into the $output variable.

You can then create page.

<html>
<body>
<form action="index.php">
<input type="text" name="address" />
<input type="submit" value="Post!" />
</form>
</body>
</html>

In the index.php you can put such code:

<?php
     if ($_POST && $_POST['address']) {
          exec ("/path/to/script " . escapeshellarg($_POST['address']), $output); 
          echo $output;
     }

where do I put "exec ("/path/to/script", $output); " in my index.php or in my bash script?

You should use escapeshellarg() around the post variable.

Well, I'm getting blank screen, where should I put escapeshellarg(), my php skills are really basic :(

@user1007727 Please, at first, please create page with such code "<?php echo 'test'; ?>" With such basic code you could ensured that webserver and php works fine, then if 'test' will be echoed I will provide you more help.
