PHP Help

I don't even know where to start.

I know I'll have to use preg, curl and file_get_content() in someway...

I want to capture the HTML code in-between a starting string and an end string.

Let's say like the starting string is <b>Member List</b>
and the end string is </td> I want it capture all the HTML code in between both and echo it.

Here's how I think it'll go.

1) Log into www.u-dominion.com using my account.

2) Then go to my clan stats page and other pages.

3) Then I want the PHP Program to find <b>Member List</b> or a string using preg.

4) Then have it echo it on my site.

I also would like this to read every minute or so, so it can be "refreshed" every minute or however it may be.

do you have a question? or just making statements?

How would I do this lol :p.

How do I get it to read from a website, and then post what it says on the other site in intervals (like 30 seconds, 1 minute etc.)?

1) It needs to log into u-dominions site
2) needs to get the page
3) needs to find a start string and an end string.
4) In between these two strings, I want it to echo the HTML.

Read up on [man]fopen[/man] & [man]fread[/man], [man]preg_match[/man], and try to write at least a mixture of code and pseudocode.

Any good sites with good example codes :. After I get the idea of how to do it, I can adapt it easily lol but I don't know where to start :.

For most of their functions, PHP.net have posted example codes in the manual. Scroll down a bit further and you will see user-submitted notes about using the functions, even functions they have created based on other PHP functions.

I wonder how many times I can say "functions" in one post? :p

Hey there,
This is one way to extract the contents between html tags (not nested). I hope this helps 🙂

<table>
<tr>
<td>

This is line 1 of 4 of text in a table cell document.

</td>
<td>This is line 2 of 4 of text in a table cell document.</td>
<td>This is line 3 of 4 of text in a table cell document.</td>
<td>This is line 4 of 4 of text in a table cell document.</td>
</tr>
</table>

function extractHTMLContents($filename, $tag) {
$filecontents = file_get_contents($filename);
$endtag = str_replace("<", "</", $tag);
$extractedtext = array();
while(($pos = strpos($filecontents, $tag, 0))) {
$contents = substr($filecontents, $pos, strlen($filecontents));
$pos01 = strpos($contents,$tag,0);
$pos02 = strpos($contents,$endtag,0);
$length = $pos02 - $pos01 - strlen($tag);
$pos01 += strlen($tag);
$text = substr($contents,$pos01,$length);

            $extractedtext[] = trim($text);

            //the rest of the contents
            $filecontents = substr($contents, strpos($contents, $endtag,0), strlen($contents));
    }

    return $extractedtext;

}

use:
<?php
return extractHTMLContents("temp0001.dat", "<td>");
?>
