the url dose not exists?

hello,

i want anything to check to see if this domain exists for example.

www.google.com

PHP:

this is good url but this one

www.hjifodszhgfiodshgfo.com

PHP:

ops there are none site like that

so is there any way to validate this with php and echo a message back

thanks in advance

 

function is_valid_dns($dns) {
if(gethostbyname($dns) == $dns)
  return false;
return true;
}

PHP:

haven´t tested it but it should work...

More information on Gethostbyname

 

no it didn't worked, this is not what im looking for.

i just want something to tell whether if the url is right and have content or wrong

the if condition is not working, if you test book.com it's going to say false and actually book.com exists

thanks for help

 

if(file('http://www.book.com')):

	echo 'EXISTS';

else:

	echo 'DOESN\'T EXIST';

endif;

PHP:

that could be a control..

 

then there´s something wrong with your server since that works on mine using

<?php

function is_valid_dns($dns) {
if(gethostbyname($dns) == $dns)
  return false;
return true;
}

if(is_valid_dns("book.com")) {
 print "true";
} else {
print "false";
}

?>

PHP:

you can see it at => http://www.qsdchublist.com/gethost.php

 

it works but the problem that when the domain is false it get me a php error like that

Warning: file() [function.file]: php_network_getaddresses: getaddrinfo failed: No such host is known. in C:\xampp\htdocs\mysite\index.php on line 23

Warning: file(http://www.bhfdshfdshfdsagook.com) [function.file]: failed to open stream: php_network_getaddresses: getaddrinfo failed: No such host is known. in C:\xampp\htdocs\mysite\index.php on line 23
DOESN'T EXIST

HTML:

so do you got any idea to only make it show DOESN'T EXIST

 

hmm, not working well it only get me true even if the domain is

www.boogbdsfgsk.com

HTML:

 

see the output of this php function, and you can use the data to see if website exists or not:

echo '<pre>'; print_r(get_headers('http://www.book.com')); exit;

Code (markup):

The reason other functions are returning an error is because the domain book.com is a 301 redirect to another url. You can see this info using this function and your script can decide if it actually exists or not.
Thanks

 

yep

if(@file('http://www.xcvaqsse.com')):

	echo 'EXISTS';

else:

	echo 'DOESN\'T EXIST';

endif;

PHP:

 

thank you so mush you are the best ;-)

thanks for everone that helped me out here

 

yea, i guess you are right, but #mehmetm give me exactly what i need thanks

 

your welcome

 

This is one of the most resource-consuming alternatives that I have ever seen to do what the OP asks for...

My suggestion:
http://php.net/manual/en/function.curl-getinfo.php
(I think there's a way to use it without executing curl_exec before)

 

i don't have that big of knowlade with php, but i think the code above works pretty well, and i tested it a lot of times and it gives me exactly what i need.

so if you do have a way to use your code and gives me the same result, tell me how can i use it, cuz on the page you gave me on php.net none people talking about it.

 

I can't afford to do your work. I just pointed you in the right direction - "teach them to fish instead of giving them the fish"

 

haha, well okay sorry for asking, now i guess im going to fish by my own hand.

thanks for help

 

<?php
$headers = get_headers("http://www.google.com", 1);
if ($headers[0] == "HTTP/1.1 200 OK" || $headers[0] == "HTTP/1.0 200 OK"){
echo "Exists";
} else {
echo "Doesn't exist";
}
?>

PHP:

 

this works but it's give me a php error if the url is wrong one try to type

www.ijngshgdslnhifds.com

HTML:

and you have to make this $headers[0] like that $headers[1]
