[SOLVED] HELP!! fopen problem

[jigen7]

i have here a function that accept a string and url site so that it will search a certain keywords if it is included or mention at a given url but some time fopen cant open a couple of sites, what i need is to have a error trapping so that if fclose cant open that site it will jsut skip the url given and return null??  im having trouble because i need the the variable where the site is so that i can use it in searching all of it line for the string given.. 

 

function search_all($url,$search_criteria){

$size = 0;

 

$the_page = fopen($url, "r"); //i think here is the line where i should edit

 

while(!feof($the_page))

{

  $each_line = fgetss($the_page, 255);

  //echo "$each_line <br>";

    if(eregi($search_criteria, $each_line, $results))

  {

      // for each line where there is a match, increment a counter

 

      $size++;

  }

}

fclose($the_page);

//print("I found $size ocurrences of $search_criteria at $url");

return $size;

 

}

fopen() returns false if the open process fails, but probably that's not your case. Why fopen() cant open specific sites? If it reads some sites, it should read them all. Are u having an error while trying to fopen() those sites?

[jigen7]

yes sometimes it gives error that it cant open the site pass url so my script gives error but when i tried to open the url it eventually open so i just need to check if ever the fopen cant open the site then i jsut have to return some value eventually

Is it readable?

[jigen7]

heres the error

 

Warning: fopen(http://www.yardbyyardfabricsandcrafts.com/store/LDpage.asp?CategoryID=8&Category_Name=Online+Shopping) [function.fopen]: failed to open stream: HTTP request failed! HTTP/1.1 403 Access Denied in E:\wwwroot\htdocs\jigen\google_search\function.php on line 55

 

so how can i trap that error so that i just have to skip checking its content if it cant open that 

 

i also check that the url (http://www.yardbyyardfabricsandcrafts.com/store/LDpage.asp?CategoryID=8&Category_Name=Online+Shopping) is accesable how come it gives me that error

If the folder is protected you'll have no access.

[Fadion]

Probably its read. To bypass the error try:

 

$handle = @fopen('page.php', 'r');
if(!$handle){
     return NULL;
}
//rest of the function's code

[jigen7]

what is the @ sign for??

[Fadion]

To surpress the error message from showing. The code does custom error handling so there's no need for error messages.

[jigen7]

ok it works so some site is protected so it cant be fopen right???so is there a way to bypass the protection?

[Fadion]

from a google search i found that to fix these http streams errors u need to update to the latest version of php5 or recompile php4 with larger FD_SETSIZE. If u are on php4 with FD_SETSIZE 1024 on a shared host, i guess theres nothing to do other then wait for them to upgrade to version 5.

[jigen7]

Here our phpinfo so it is not updated enough o well ill just try to ask if it can be updated so that the fopen can be use properly

thx for everyone helping me in my prob i got the proper coding by using curl library i was able to create another function that checks the url for a certain ketwoord here the final function

 

function search_call($url,$search_criteria){

$size = 0;

 

$ch = curl_init();

// set URL and other appropriate options

curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

 

// grab URL, and return output

$output = curl_exec($ch);

 

// close curl resource, and free up system resources

curl_close($ch);

 

if (eregi($search_criteria, $output)) {

    $size = 1;

}

return $size;

 

}
