Perhaps the proc_open function in PHP may do this?<br />
<br />
<a href="http://au.php.net/manual/en/function.proc-open.php" rel="ugc">http://au.php.net/manual/en/function.proc-open.php</a><br />
<br />
Unfortunately, I do not have any experience with this function. Or even know if it will stream the data for you?<br />
<br />
Sorry that I can't give you a definitive answer. &nbsp;But good luck and I'm keen to hear if you find a solution :)

I found the answer on one of the php doc pages.<br />
You just have to set:<br />
ob_implicit_flush(true);<br />
ob_end_flush();<br />
<br />
at the beginning of the php.<br />
<br />
Thanks for the help!<br />

I am looking for a way to run call an external system command and capture the output to display to the browser in real time. This external script runs for a long time (2 mins or so) so it would be great if there was a way for this output to come to the browser in semi realtime.<br />
<br />
The script I'm running is a perl script, so alternatively the script could to display output could be in perl.<br />
I'm running Linux and Apache.<br />
Thanks in advance.

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.

Perl is a high-level, general-purpose, interpreted, dynamic programming languages with over 25 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large-scale development projects.  Perl gained widespread popularity as a Common Gateway Interface (CGI) scripting language, in part due to its regular expression and string parsing abilities. In addition to CGI, Perl is used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications.
