PHP LOAD ARRAY VARIABLE FROM FILE

Question

i have the following code:

which uses an array to write the result to file

i want to create another array to read the celebities aray from another file

<?php
require("class.XMLHttpRequest.php");
function hot($news){
 $url="https://localhost/search.aspx?search=".$news.""; 
 $ajax=new XMLHttpRequest();
 $ajax->setRequestHeader("Cookie","Cookie: host");
 $ajax->open("GET",$url,true);
 $ajax->send(null);
 if($ajax->status==200){
  $rHeader=$ajax->getResponseHeader("Set-Cookie");
  if(substr_count($rHeader, "Present!")>0) { return true; }
 }else{ return false; }
} 
$celebrities = array('britney','gaga','carol');
$filename = 'result.txt';
$handle = fopen($filename, 'a');
foreach($celebrities as $celebrity)
{
    if(hot($celebrity)) { fwrite($handle, "{$celebrity}\r\n"); };
}
fclose($handle);
?>

and i would like to load the $celebrities array from a file instead of

$celebrities = array('britney','gaga','carol');

i couldnt get to implement this one here: what am i doing wrong ?

<?php
$handle = @fopen('array.txt', "r"); 
if ($handle) { 
   while (!feof($handle)) { 
       $celebrities[] = fgets($handle, 4096); 
   } 
   fclose($handle); 
} 
?>

Answer 1

Since you're separating each array entry by a newline/carriage return, you should read in the contents of the file line by line and assign each to your array, which it looks like you're doing. Perhaps declaring the array before you use it will help, i.e. $celebrities = array(); before your loop. Otherwise it looks like $celebrities is getting redefined every time your loop iterates.

If you provide more information on what is not working (parse error? contents of the array?) then I could provide a more detailed answer.

If the code doesn't give an error, print out the contents of the array print_r($celebrities); and show us your output.

Answer 2

I don't see any problem with your code. What exactly doesn't work? Any error messages?

Why are you reading the file into an array? My suggestion:

$read_file = fopen('array.txt', 'r');
$write_file = fopen('result.txt', 'a');

while(!feof($read_file))
{
    $celebrity = trim(fgets($read_file));
    if(hot($celebrity)) { fwrite($write_file, "{$celebrity}\r\n"); }
}

fclose($write_file);
fclose($read_file);

Answer 3

$celebrities = file('array.txt'); // possibly add an array_filter()

// OR
$celebrities = explode('\r\n', file_get_contents('array.txt'));
