help/advice needed

[Paradox123]

Hello, basically i'm writing a php script which connects to my website and see's if the url is valid It has no real use but is just for practice as i'm new to php.

 

it reads from website.txt to get the website ($url) and then reads from directory.txt to get the directory i want tested ($dir) e.g. "www.mysite.com/lol.php".

if www.mysite.com/lol.php IS valid, it will save to output.txt  and if (for example) www.mysite.com/notlol.php is NOT valid then doesn't save to output.txt.

 

So far the read/write to file is working fine i'm just having problems with checking the site is actually valid.

 

The code i was using to check this is as follows.

 

$wtf = $url . $dir;


//curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); <-- this is only commented out whilst i test the code
curl_setopt($ch, CURLOPT_URL, $wtf);
curl_setopt($ch, CURLOPT_HEADER, 0);
$res = curl_exec($ch);
if(!$res) die("Error Connecting To Target");
$res = strstr($res, $dir);
if(!$res) die("Not found");

 

You will probably notice the problem is on the "$res = strstr($res, $dir);"  this looks like this because i was getting desparate and was trying pretty much everything i could think of. This code gives a positive every time so saves to output.txt even when the site + url doesn't exist.

 

My question is, what would i have to change to make it write to output.txt only if the site + url DOES exist? And is there a better (easier) way of accomplishing this than above?

 

Thanks a lot in advance, any thaughts/ideas are welcome.

it might sound retarded me asking this, but sometimes this is the case:

 

have you installed cURL yet?

[Paradox123]

Hehe yes, if you look i've got "//curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);" commented out, so i can see that it's connecting to the site alright.

 

Thanks anyway.

small class a wrote a while ago to ping stuff

<?php
class ping{
var $url = "http://www.google.com";

function ping_it(){
	$ch = curl_init();
	curl_setopt ($ch, CURLOPT_URL,$this->url);
	curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
	curl_setopt($ch,CURLOPT_VERBOSE,FALSE);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
	curl_setopt($ch, CURLOPT_TIMEOUT, 15);
	$this->page_data = curl_exec($ch);
	$url_info = curl_getinfo($ch);
	if(count($url_info)>0){
		$this->returned = $url_info;
	}
	else{
		$this->error_report("Could not't find url.",1);
	}
	curl_close($ch);
}
function print_return(){
	echo "<ul class=\"ping_return\">\n";
	foreach($this->returned as $key=> $value){
		echo "<li>".$key.": ".$value."</li>\n";
	}
	echo "</ul>\n";
}
}
?>

to use include the class and say

<?php
$ping = new ping;
$ping->url = "YOUR URL HERE";
$ping->ping_it();
$ping->print_return();
?>

Can you not use an if statement .e.g.

if(file_get_contents)

{

 

}

 

or something similar?

Yeah I can finally change it first person ever to call ti as it is hemimellitene (got 1,2,3-trimethylbenzene a million times)

I don't really understand what you mean - i'm new to php - i know what if statement is but not sure how i can use that to test if the adress is valid.

i believe it will be

if(file_get_content("url"))

{

echo "Page exists";

}
