url parser?

[wsh]

URL parser? anyone know where I can find something that does what the:

Automatically parse URLs: automatically adds and around internet addresses.

option does? I am making a guestbook and thought it would be neet if I could have it put the <a href="$url">$url</a> in for the poster.

[wsh]

or- could someone explain how to use ereg_replace or something to look at a string and take a part out as a variable to be using in the replace part

for example (since i a bad at explaining):

$str=ereg_replace("/<a href=\"(.1)\">(.2)<\/a>/","<a target=_top href=\"$1\">$2</a><BR><font face=arial size=1>URL: $1",$str);

WHERE (.1) it extracts it as a variable $1 in this case and puts it back in throughout the files and where (.2) it extracts it as a varibale $2 in this case

I KNOW IT IS POSSIBLE but how? THANKS!

Maybe you could try something like this:

$str="<a href=\"http://phpbuilder.com/forum\">PHP Builder Forum</a>";
$str1 = ereg_replace ("<a[^>]+href *= *([^ ]+)[^>]*>", "\\1", $str);
$str2= preg_replace ("'<[\/\!]*?[^<>]*?>'si",  "", $str);
$str3="<a target=_top href=\"$str1\">$str2</a><BR><font face=arial size=1>URL: $str1";

This may not be exactly what you are looking for, but I hope it helps.

Let me know!

in $str1 .......
,"\1" should be ,"\1"

sorry about that

[wsh]

genius! thanks

You seem to know what your doing with ereg and regular expressions... maybe you or someone could help with this problem???

I have an HTML document stored into a variable ($html) and I want to go through it looking for links (<a(.)href=(.)[url]http:///url"(.)>(.*)</a>) -they could be in any form... I want to make sure that none of the links are to redirector pages (example: <a href=http://www.somesite.com/redir.php?rawto=http) it could say anything before the second http, but they all start with http right after the href=" or href= ... basically I want to use the raw URLs not the whole redirection script... by anything I mean it could be http://sub.site.net/whatever/maybe/some/dirs/maybsome.script?maybesome=vars&maybe=others&somevar=http
The main problem being that after the second http (the real url) the url is in some wiered url language for example / is %2F and crap like that... I want it changed into normal [url]http://[/url] not http(whatever the colon is)%2F%2F .. you know th e% representations and crap like that, that using GET changes them into in forms... maybe replace the redir url with the url then replace the %2F and all that with the real thing...... o and some things hrefs may be the actual url not redir scripts

LOL! 😃 Ok.. maybe I should come up with an idea before asking people to write things for me, huh?😉! Maybe you could help and tell me if this would work?! 😕

preg_replace("/(http(.))+http(.)/","http\3",$html);
$html = str_replace("%2E",".",$html);
$html = str_replace("%2F","/",$html);
$html = str_replace("%3A",":",$html);

that should work, write😕?! Plz advise:p! THX😃

[JDcrack]

Yes that should work!

Take a look at these links:
http://www.php.net/manual/en/function.htmlspecialchars.php
http://www.php.net/manual/en/function.str-replace.php
http://www.php.net/manual/en/function.ereg-replace.php
http://www.php.net/manual/en/function.preg-replace.php
http://www.php.net/manual/en/function.strip-tags.php
http://www.php.net/manual/en/function.urldecode.php

[wsh]

Thanks for the confirmation... the old rtfm, huh! Sorry about that... maybe you know of a function that can read the GET code?... dont know what its called or how to convert it so I figured that I would just str_replace them..

[JDcrack]

Again,
Its all in the manual 😃

[wsh]

THX! How the f* do you find these things?!!! I looked at the manual for like an hour then got bored and figured it wasnt in the manual... o well... i aint no genius.... lets see if you can further amaze me....

My last problem (as far as I can see...) I can ALMOST guarantee that this will not be in the manual.. exept if someone posted it in the user comments.. doubt that...

I want to search a database without using FULLTEXT... I DO HAVE A REASON FOR THAT!!!! IM NOT THAT BIG OF AN IDIOT 😃!!!!

Ok... I need to split up the search string into words

$strarray = explode(' ',$q);

($q is the search var)

Then I need to search the database and select all the rows that contain each word

foreach ($strarray as $stritem) {
$res = mysql_query("SELECT * FROM searchtable WHERE keywords LIKE('%$stritem%') LIMIT 0, 10");
while($row=mysql_fetch_array($res11)) {
 if($row[URL] != "" AND $row[Description] != "" AND $row[Title] != "") {
  echo "url: $row[URL] title: $row[Title] description: $row[Description]";
}
}
}

Now... how do I prevent the same row from being displayed twice??? The URL column is a unique key so it can .. i think... be done by putting each row's url into an array as we go and then before displaying the results (echo) we test if the url is in the array

if(in_array($row[URL],$url) != TRUE) {
  echo "url: $row[URL] title: $row[Title] description: $row[Description]";
}

Now how do I make it put each URL into an array.. and make it so that in_array works??!? plz help or suggest new way.

To answer your first question about duplicate values in the array:

As for your other questions,
I really think you ought to spend some time on this page.
