[How do I Insert A Var In A URL Function]

I need to insert 2 variables into a url that is part of a function and can't seem to do it. I know the code below has an error in it and am thinking I need to make $_SERVER[REMOTE_ADDR] and http://" . $_SERVER[SERVER_NAME] . $_SERVER[REQUEST_URI]; some sort of a var but am clueless how to do it.

Any help will be greatly appreciated.



The following code is a snip of the code.


[code]

return $children;
}
$url = "http://domain.com/xml_feed.php?p_id=1002&ad_count=5&channel=1&doc_offset=0&keyword=entertainment&limited=0&uip=$_SERVER[REMOTE_ADDR]&referring_page=$page_url ="http://" . $_SERVER[SERVER_NAME] . $_SERVER[REQUEST_URI];"; //URL of the XML FEED

$contents = file_get_contents($url);

$data = GetXMLTree ($contents);
[/code]

[Calling Script In Page Build]

I am wanting to run this scrip so that the code is called as an include_once and then get the a variable and finally prints the items.

The page is built by calling 5 different dynamic sections.

My Thought was I could include this in the header of the page as a php file:

[code]

<?php
function GetXMLTree ($xmldata)
{
    // we want to know if an error occurs
    ini_set ('track_errors', '1');

    $xmlreaderror = false;

    $parser = xml_parser_create ('ISO-8859-1');
    xml_parser_set_option ($parser, XML_OPTION_SKIP_WHITE, 1);
    xml_parser_set_option ($parser, XML_OPTION_CASE_FOLDING, 0);
    if (!xml_parse_into_struct ($parser, $xmldata, $vals, $index)) {
        $xmlreaderror = true;
        echo "error";
    }
    xml_parser_free ($parser);

    if (!$xmlreaderror) {
        $result = array ();
        $i = 0;
        if (isset ($vals [$i]['attributes']))
            foreach (array_keys ($vals [$i]['attributes']) as $attkey)
            $attributes [$attkey] = $vals [$i]['attributes'][$attkey];

        $result [$vals [$i]['tag']] = array_merge ($attributes, GetChildren ($vals, $i, 'open'));
    }

    ini_set ('track_errors', '0');
    return $result;
}

function GetChildren ($vals, &$i, $type)
{
    if ($type == 'complete') {
        if (isset ($vals [$i]['value']))
            return ($vals [$i]['value']);
        else
            return '';
    }

    $children = array (); // Contains node data

    /* Loop through children */
    while ($vals [++$i]['type'] != 'close') {
        $type = $vals [$i]['type'];
        // first check if we already have one and need to create an array
        if (isset ($children [$vals [$i]['tag']])) {
            if (is_array ($children [$vals [$i]['tag']])) {
                $temp = array_keys ($children [$vals [$i]['tag']]);
                // there is one of these things already and it is itself an array
                if (is_string ($temp [0])) {
                    $a = $children [$vals [$i]['tag']];
                    unset ($children [$vals [$i]['tag']]);
                    $children [$vals [$i]['tag']][0] = $a;
                }
            } else {
                $a = $children [$vals [$i]['tag']];
                unset ($children [$vals [$i]['tag']]);
                $children [$vals [$i]['tag']][0] = $a;
            }

            $children [$vals [$i]['tag']][] = GetChildren ($vals, $i, $type);
        } else
            $children [$vals [$i]['tag']] = GetChildren ($vals, $i, $type);
        // I don't think I need attributes but this is how I would do them:
        if (isset ($vals [$i]['attributes'])) {
            $attributes = array ();
            foreach (array_keys ($vals [$i]['attributes']) as $attkey)
            $attributes [$attkey] = $vals [$i]['attributes'][$attkey];
            // now check: do we already have an array or a value?
            if (isset ($children [$vals [$i]['tag']])) {
                // case where there is an attribute but no value, a complete with an attribute in other words
                if ($children [$vals [$i]['tag']] == '') {
                    unset ($children [$vals [$i]['tag']]);
                    $children [$vals [$i]['tag']] = $attributes;
                }
                // case where there is an array of identical items with attributes
                elseif (is_array ($children [$vals [$i]['tag']])) {
                    $index = count ($children [$vals [$i]['tag']]) - 1;
                    // probably also have to check here whether the individual item is also an array or not or what... all a bit messy
                    if ($children [$vals [$i]['tag']][$index] == '') {
                        unset ($children [$vals [$i]['tag']][$index]);
                        $children [$vals [$i]['tag']][$index] = $attributes;
                    }
                    $children [$vals [$i]['tag']][$index] = array_merge ($children [$vals [$i]['tag']][$index], $attributes);
                } else {
                    $value = $children [$vals [$i]['tag']];
                    unset ($children [$vals [$i]['tag']]);
                    $children [$vals [$i]['tag']]['value'] = $value;
                    $children [$vals [$i]['tag']] = array_merge ($children [$vals [$i]['tag']], $attributes);
                }
            } else
                $children [$vals [$i]['tag']] = $attributes;
        }
    }

    return $children;
}
$url = "http://text.dynamicmedia.us/ads/xml_feed.php?p_id=1002&ad_count=10&channel=1&doc_offset=0&keyword=creditcards&limited=0&uip=82.35.20.94&referring_page=http://dynamicmedia.us/index.php"; //URL of the XML FEED

$contents = file_get_contents($url);

$data = GetXMLTree ($contents);


function print_ad_item($item) {
        echo '<p>';
        echo $item['Heading']."<br />\n";
        echo $item['URI']."<br />\n";
        echo $item['Description']."<br />\n";
        echo $item['URL'];
        echo '</p>';
}

function print_line_item($item) {
    echo '<p>';
    echo "<a href=\"{$item['URI']}\" target =\"_blank\" onMouseOver=\"window.status='{$item['URL']}'; return true;\"onMouseOut=\"window.status=''; return true;\">{$item['Heading']}</a><br />\n";
    echo '<br />';

}

function print_textad_item($item) {
    echo '<p>';
    echo "<a href=\"{$item['URI']}\" target =\"_blank\" onMouseOver=\"window.status='{$item['URL']}'; return true;\"onMouseOut=\"window.status=''; return true;\">{$item['Heading']}</a><br />\n";
    echo $item['Description']."<br />\n";
    echo '</p>';
}

$textad = $data['Ads']['Listing'];

?>

[/code]


The line:
[code]
$url = "http://text.dynamicmedia.us/ads/xml_feed.php?p_id=1002&ad_count=10&channel=1&doc_offset=0&keyword=creditcards&limited=0&uip=82.35.20.94&referring_page=http://dynamicmedia.us/index.php"; //URL of the XML FEED
[/code]

could be inserted in the page as it is built since I need to insert a variable or two - specifically a keyword, the referring page, and the visitors IP address, I thought I could do this outside of the php file i am including in the header. But.... im not sure how that would be done?


Then I wanted to insert the following to print the results into 2 different areas a the dynamically created page.


<?
print_line_item($textad[0]);


print_textad_item($textad[1]);
print_textad_item($textad[2]);
print_textad_item($textad[3]);
print_textad_item($textad[4]);
print_textad_item($textad[5]);
print_textad_item($textad[6]);
print_textad_item($textad[7]);
print_textad_item($textad[8]);
print_textad_item($textad[9]);


?>


The problem I have is i only get an error - no other details. I am a total nuuuubie to php and think im a bit over my head on this one.


Any help will be greatly appreciated.

You missed a "slash"... This should do it...
[code]
function print_link_item($item) {
echo '<p>';
echo "<a href=\"$item['URI']\" target =\"_blank\" onMouseOver=\"window.status='$item['URL']'; return true;\" onMouseOut=\"window.status=''; return true;\">$item['Heading']</a>
echo '</p>';
}
[/code]
[/quote]


Hummm still not working and getting the parse error.

I even tried this:
[code]
function print_link_item($item) {
echo '<p>';
echo "<a href=\"$item['URI']\" target =\"_blank\" onMouseOver=\"window.status='$item['URL']'; return true;\"onMouseOut=\"window.status=''; return true;\">$item['Heading']</a>";
echo '</p>';
}
[/code]
and it also returned the parse error.

A stupid qustion on my behalf - in the original snip the var had a "." after it
[code]
function print_link_item($item) {
        echo '<p>';
        echo $item['Heading']."<br />\n";
        echo $item['URI']."<br />\n";
        echo $item['Description']."<br />\n";
        echo $item['URL'];
        echo '</p>';
}
[/code]

Why is a . not used in this example?

[code]
function print_link_item($item) {
echo '<p>';
echo "<a href=\"$item['URI']\" target =\"_blank\" onMouseOver=\"window.status='$item['URL']'; return true;\" onMouseOut=\"window.status=''; return true;\">$item['Heading']</a>
echo '</p>';
}
[/code]

Thanks for the help, I tried your code but have got the following error:

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING

Im new to php and havent got a lot of experience.

[Making This URL Work with Vars -]

I need to take this array and have it print.

function print_link_item($item) {
echo '<p>';
echo $item['Heading']."<br />\n";
echo $item['URI']."<br />\n";
echo $item['Description']."<br />\n";
echo $item['URL'];
echo '</p>';


I want to have the Heading display the Link and when the user mouse overs the link instead of seeing the URI (real url) they will see the [URL] i want them to see.

How do I make the following work, I have fiddled with it and just cant make it work.

<a href="[URI]" target = '_blank' onMouseOver="window.status='[URL]'; return true;" onMouseOut="window.status=''; return true;">[Heading]</a>

Thanks
