I would look at what term you are using and how that differs from PHP to expect. Also create a basic php script to execute the expect script and see if it works through cli. if that works then check through apache. if it fails through apache it might be because of a term issue.<br>

<div><font color="#333333" face="Lucida Sans" size="2"><span style="font-size: 10pt; color: rgb(51, 51, 51);">I have a webpage that is in HTML and PHP. In PHP I have tried using exec, system, shell_exec and passthru functions to call an Expect Script file (temp.exp). This expects file spawns a telnet session that uses "expect/send" commands to retrieve information from an environmental unit (not a normal server). This data is placed in a file and then loaded to the webpage. <br>
<br>
The problem is if I call "./temp.exp" it runs great, but when I call the same program from the webpage exec("./temp.exp") using PHP (because it retrieves the data is displayed in the webpage), it will connect but then stops responding. It never returns the password prompt to achieve a yes to move on. <br>
<br>
I inserted "exp_internal 1" in the expect file to produce the diagnostic results. <br>

I have checked/changed the Apache user, the permissions and ownership of the files are fine. I have put debug on the expect and the telnet sessions. I have specified the telnet used and the port. I have upgraded my Tcl/Tk. The link <a title="http://unix.derkeiler.com/Newsgroups/comp.unix.shell/2005-06/0454.html" href="http://unix.derkeiler.com/Newsgroups/comp.unix.shell/2005-06/0454.html" target="_blank">http://unix.derkeiler.com/Newsgroups/comp.unix.shell/2005-06/0454.html</a> is similar but I am not getting the "setsocket(SO_DEBUG):Permission denied" error and that solution did not work for me. </span></font></div>
