Help with PHP and shell_exec!!!

Hi, I've been working on a PHP script which is "supposed" to find an individuals weather based on their geolocation. This script uses "shell_exec".

I have checked my syntax and it is correct, but there is still something missing; for when I call on the script using:

Code:

<form action='/weather.php' method='get'><br>
<input type='submit' name='submit' value='Check'><br>
</form>

I get a blank page Smilie

Here is my script:

Code:

<?php

function getWeather() {
$ip = $_SERVER['REMOTE_ADDR']; 
$geo = shell_exec("/usr/bin/curl -s api.hostip.info/get_html.php?ip=$ip | /usr/bin/sed -e '1d;3d' -e's|C.*:||' -e's/...\(.*\)/\1/' -e's|-|%2d|' -e's/ /%20/' -e\s/'/%27/'");
$getAddress = "http://www.google.com/ig/api?weather=$geo";
$xml_str = file_get_contents($getAddress,0);
$xml = new SimplexmlElement($xml_str);
$count = 0;
echo '<div id="weather">';

foreach($xml->weather as $item) {

        foreach($item->current_conditions as $new) {

            echo '<div class="weatherIcon">';
            echo '<img src="http://www.google.com/' .$new->icon['data'] . '"/><br/>';
        echo $new->condition['data'];
            echo $new->temp_f['data'];
            echo $new->temp_c['data'];
            echo $new->humidity['data'];
            echo $new->wind_condition['data'];
            echo '</div>';
            }

        foreach($item->forecast_conditions as $new) {

            echo '<div class="weatherIcon">';
            echo '<img src="http://www.google.com/' .$new->icon['data'] . '"/><br/>';
            echo $new->day_of_week['data'];
            echo $new->condition['data'];
            echo $new->low['data'];
            echo $new->high['data'];
            echo '</div>';
            }

    }

echo '</div>';
}

getWeather();

?>

I'm a bit of a noob when it comes to this, so any help would be greatly appreciated. Thanks.

Jared

tcl_allowexceptions

Tcl_AllowExceptions(3)                                        Tcl Library Procedures                                        Tcl_AllowExceptions(3)

__________________________________________________________________________________________________________________________________________________

NAME

       Tcl_AllowExceptions - allow all exceptions in next script evaluation

SYNOPSIS

       #include <tcl.h>

       Tcl_AllowExceptions(interp)

ARGUMENTS

       Tcl_Interp *interp (in)          Interpreter in which script will be evaluated.
_________________________________________________________________

DESCRIPTION

       If  a  script is evaluated at top-level (i.e. no other scripts are pending evaluation when the script is invoked), and if the script termi-
       nates with a completion code other than TCL_OK, TCL_ERROR or TCL_RETURN, then Tcl normally converts this into a TCL_ERROR  return  with  an
       appropriate  message.  The particular script evaluation procedures of Tcl that act in the manner are Tcl_EvalObjEx, Tcl_EvalObjv, Tcl_Eval,
       Tcl_EvalEx, Tcl_GlobalEval, Tcl_GlobalEvalObj, Tcl_VarEval and Tcl_VarEvalVA.

       However, if Tcl_AllowExceptions is invoked immediately before calling one of those a procedures, then arbitrary completion codes  are  per-
       mitted from the script, and they are returned without modification.  This is useful in cases where the caller can deal with exceptions such
       as TCL_BREAK or TCL_CONTINUE in a meaningful way.

KEYWORDS
