Stripping text

Relyt

I need help stripping lines of text between a certain set of characters. For example a list of urls all startting with http://www.
i want to strip the http://www. so is that i can then take the actual domain names and find any duplicates.

Post your code sample ( you know how to copy and paste ? )
and somebody here will insert this function into PHP

<?php
echo 'Hello, Relyt!';
?>

This is a very easy thing! To strip parts of strings.
🙂

problem is, i dont know a thing about php coding. I only know the basis to programming. i want a simple program for my personal use that works like this.

If text between www. and end of line = the same

Then delete text, store one set in a database(or text file) and move on to next line

else move on to next line

I need this becasue i have a list of over 500 URLs that i need to sort alphabeticaly and remove any duplicates.

If someone was kind enough to copy and paste some code that did this for me, id be ever so thankful.

Hi Relyt,

Something like:

$stringtoreplace = "http://www.";
$replacestring = "";
$instring = "http://www.mydomain.com";

$replaced = str_replace($stringtoreplace,$replacestring, $instring);

Hey Halo, did you really need an example for this?

Relyt

from what i can tell, that should work along with a bit more code im going to have to learn...lol.....but thank you for the help.

Hi Relyt,

You will need to look at:

and you need do do something like:
-> Read the file to memory, into an array
-> Use
array_unique to get the unique values out.

I do not think you'd have to strip the [url]http://[/url] part. You might want to explode the url's to get only the domein, without pages / folder attatched.

Relyt

maybe im over my head with this one. I should go back and learn php from the "hello world" part....lol

But i can give it a try i guess, unless someone wants to code the whole program for me.

Iv even thought of doing this in Visual basics, since im more familular with it.

leatherback

No...!

Do not give up that eassily! I bet you have though.. A manual.. Nope. i'll ask. But this manual is different. It is full of examples etcetc.

Have a look here and you will see that getting a file into an array is a piece of cake (Granted, a big piece but..)

And then look ta the array_unique function I posted.

WHen you get stuck, give us the code you get stuck with, and we'll ease you through. Most of us started like this.

Yes!!!
I am afraid I am not as experienced as I can sound. 😃
Actually I am quite new writing php. But learning very fast.
Still I have to consult php manual for most functions.
In some few other areas, I know very much.

Takes time to learn, before knowing most of it by heart.
Like taking drivers's licence.
By time driving is in your backbone. You do not need to think.
Hope get there one day. With php.

Relyt

thanks for the confidence, i guess i will give this a try, but it might take me a day or 2, since i got other things that have to get done today aswell. But i hope when i get stuck, your gonna be around to pry me out 😉

Hey Halo,

When you get there with PhP, you might want to give MySQL a try. It makes life much easier -although I agree you can do many things with files too).

Still.. Linked lists, multi-table searching.. It is a bit of a hassle with files only.

No thanks, I am truthful when I say I do not need mySQL.
Not when writing my own scripts. (But I use downloaded scripts with mySQL)

As a matter of fact,
I have written my own PHP Database flockwrite fread Class myDB
with a simple userfriendly syntax

In this little, less than 10kB, Add-On API,
I have only one database, per application, and creates tables only.

It works well.
Last additions to my class was
$mydb->exporttable( $tname )
$mydb->importtable( $tname )
Good for back up purposes.

<?
//replace [url]http://[/url] or www. with nothing

function site_sort() {
global $sites;

$sites = str_replace("www.","",$sites);
$sites = str_replace('<a href=\"',"",$sites);
$sites = str_replace('\"',"",$sites);
$sites = explode(" ",$sites);
$sites = array_unique($sites);
sort($sites);

$i = "0";
foreach ($sites as $site) {
if ($site != "") {

if (stristr($site,".")) {
echo $site;
echo " ";
$i++;
} else {
echo $errstr;
}

}
}
echo " ------------------------------------------Total Count: ".$i;

}

its still not stripping and sorting it enough....anyone know anything about regular expressions?

Is there anyway of stripping out full words?

I was told i need to use regular expressions

Relyt
