Scan a variable

[jamesm87]

Hi.

Is it possible to check if a variable includes a bit of text. For example if someone sent a website with [url]HTTP://[/url] at the begining of the variable (or web address sent) i would like to remove the [url]HTTP://[/url] part and leave the rest.

thankyou

James

These probably should work:

$url = str_replace("http://", "", $url);

or

$url = preg_replace("/^http:\/\//", "", $url);

[jamesm87]

thankyou. That works fine. Is it also possible to put it into a If Command to check if it does include [url]http://[/url] at the begining.

eg

if ($webadd  // has http in it
    {

     $url = str_replace("http://", "", $url); 
}

else ($webadd // has not got [url]www.[/url]
    {
         $url2 = "http://";
         $url2 .= $url;
     }
[code=php]

Thankyou!

One way might be:

<?php
if (preg_match("/^http:\/\//", $webadd) == 1) {
	//remove "http://"
}
elseif (preg_match("/www\./", $webadd) == 1) {
	//do whatever else
}
?>

Warning: Unknown modifier '/' in /home/hollyfie/bpb/go.php on line 19

This came up when I did that. Line 19 is

if (preg_match("/^{[url]http:///[/url]",} $webadd) == 1)

Any idea's

Thanks 🙂

if([man]substr/man=='http://')

if([man]strpos/man===0)

if([man]preg_match/man)

...

[jamesm87]

Which is which? Thanks for your help 🙂

It maybe easier to send in the script.

The Form is as follows =

Webadd = website address or Keyword

It is possible for someone to write a keyword like google and goes straight to google.

<?php

include("config.inc.php");//mysql variables
include("connect.php");//connect to mysql server



if (!isset($webadd))
{
	header("Location: [url]http://hollyfield.port5.com[/url]");
}



if(substr($webadd,0,7)=='http://') // This should be if there is a HTTP (is it correct command?)
	{
header("Location: $url");
}



$sql = "select * from BPB_keywords where keyword=('$webadd')";
                $result=mysql_query($sql)
	or die ("cant do check!");
	$all= mysql_fetch_array($result);
	$num= mysql_num_rows($result);



if ($num == 1)
{
	extract($all);

if (isset($popup))
	{
echo '<script language="Javascript">alert ("A message before you load this website: $popup")</script>';
	}
	header("Location: $url");
}

if(preg_match('![url]http://[/url]!',$webadd)) //If their is not a http...
{
$url = "http://www.".webadd;   //    ...it adds one 
			header("Location: $url");
}
?>

Is their anything i need to change for it to work? thanks!

Sorry, I forgot to escape the slashes
(or rather the forum parser parsed them out and I didnt check)

<?php
if (preg_match("/^http:\\/\\//", $webadd) == 1) {
    //remove "http://"
}
elseif (preg_match("/www./", $webadd) == 1) {
    //do whatever else
}
?>

[jamesm87]

Erm... whats the difference between the two? ;-)

Take your pick; I gave you links to the functions' manual pages so's you could see what they did.

[jamesm87]

sorry didn't notice the links 🙂 .

Is it possible to scan a website, put the HTML into a variable and echo it all through a php script?
