Array problems

[Sven Dzepina]

Hello,

How I can realize that?
I have this code:

<?php
$url = "http://www.URL.com;
$content = file($url);
foreach($content as $line){
$pattern =
"/([\w]+:\/\/[\w-?&;#~=\.\/\@]+[\w\/](\.(html|php|shtml|htm|xhtml|xml)))/i";

$count = 0;
if(preg_match_all($pattern,$line,$urls_back_array) ){
foreach($urls_back_array[0] as $url_back){
$count++;
echo $url_back;
}
}
}
?>

Now I want to make a loop - My script should count all links of all my *html
sites. But the script are not allowed to count double! Also the script shall
count all links on html sites correctly!
Example:
Home
|-Web
|-Forum
|--Site 1
|--Site 2
|--Site 3
|-Download
It should count 7 and list me all! =)

I'm playing around here trying to do what you want to do... I'm not good
with my regular expressions using preg tools but I am using a mixture of
implode and explode to get at the url of each link (ie the "href=" bit in
the <A HREF" tag)... Once I have the website address that the link is
targeted at, I plan on using a mix of parse_url() and pathinfo() to identify
html type files. And in order to avoid duplices, the address will be
written in to an array which I will then run against array_unique.

Do these ideas help any?

I didn't check your regex.

I'd do it somewhat differently:

after preg_match_all() put the URLs into the index part of an array
### should this be __1__ ?
foreach ($urls_back_array[0] as $url_back) {
$large_url_array[$url_back]++;
## no echo
}
} ## if
} ## foreach

## echo now!
$total_count = 0;
$unique_urls = 0;
foreach ($large_url_array as $url=>$count) {
echo $url, ' : appears ', $count, ' times<br />';
$total_count += $count;
$unique_urls++;
}
echo '<br />Unique URLs: ', $unique_urls, '<br />';
echo '<br />Total links: ', $total_count, '<br />';

Hello Rondell,

perhaps I've explained my aim imprecisely.
I want to count all Sites, which are linked on a homepage and list them.
My earlier solution was, that I have scanned all links and then I have
listed them all in a database.
But, it was a loop and so I fetched all links from the database to scann
them, too!
I didn't thought on this problem:
If I scann all links and insert them into a database, and I fetch them in
the same loop - Then I get always the same links.
