PHP Outputting results based on greater than/less than from JSON - php

Question

I am trying to get this script to output results based on a greater than/less than script. When I run this script all it does it output the first line in the text file. Any suggestions as to what I am missing?
<?php
$lines = file('unique.txt'); // Reads the file with the list of user numbers
$timestamp = time(); // Defines time for below renaming
foreach ($lines as $usernumber) { // Loops line by line
$link = 'http://backpack.tf/api/IGetUsers/v2/?&steamids=' . $usernumber . '&format=json';
$json = file_get_contents($link); // Reads link (this ^)
$data = json_decode($json); // Defines decode as json
if (!empty($data)) {
$profiles = array(); //init array so we can use $profiles[] later
foreach ($data->response->players as $player) { // Loop thrugh all the players
$player2 = $player->backpack_value;
if ($player2 < 9999999) { // Check the backpack_value
$profiles[] = $player; // Assign the required players to a new array
var_dump($profiles); // Dump the array to browser for debugning
$fh = fopen("final." . $timestamp . ".txt", 'a') or die("can't open file"); // Opens final.txt to write in
fwrite($fh, $usernumber); // Writes the parsed results to final.txt
} //closes if $playtime
} //closes foreach $data
} //closes if !empty
else {
echo $data;
}
} //closes foreach $lines
?>
Unique.txt contains
76561197992831594
76561197992707820
76561197992146126
76561197992694522
76561197992707820
76561197992831594
JSON Example

Okay There is two fundamental problems.
The fopen call needs to move outside of the loop.
the file call has an annoying habit of keeping the trailing newline. When you are building up your url you should use trim($usernumber) to get rid of it.
Here is an update with those two things in place.
<?php
$lines = file('unique.txt'); // Reads the file with the list of user numbers
$timestamp = time(); // Defines time for below renaming
$fh = fopen("final." . $timestamp . ".txt", 'a') or die("can't open file"); // Opens final.txt to write in
foreach ($lines as $usernumber) { // Loops line by line
$link = 'http://backpack.tf/api/IGetUsers/v2/?&steamids=' . trim($usernumber) . '&format=json';
$json = file_get_contents($link); // Reads link (this ^)
$data = json_decode($json); // Defines decode as json
print_r($json);
if (!empty($data)) {
$profiles = array(); //init array so we can use $profiles[] later
foreach ($data->response->players as $player) { // Loop thrugh all the players
$player2 = $player->backpack_value;
if ($player2 < 9999999) { // Check the backpack_value
$profiles[] = $player; // Assign the required players to a new array
var_dump($profiles); // Dump the array to browser for debugning
fwrite($fh, $usernumber); // Writes the parsed results to final.txt
} //closes if $playtime
} //closes foreach $data
} //closes if !empty
else {
echo $data;
}
} //closes foreach $lines

I've done this with CURL and it works too.
The code:
$lines = array('76561197992831594','76561197992707820','76561197992146126');
$timestamp = time(); // Defines time for below renaming
foreach ($lines as $usernumber) { // Loops line by line
$link = 'http://backpack.tf/api/IGetUsers/v2/?&steamids=' . $usernumber . '&format=json';
$json = curl_download($link); // Reads link (this ^)
$data = json_decode($json); // Defines decode as json
if (!empty($data)) {
$profiles = array(); //init array so we can use $profiles[] later
foreach ($data->response->players as $player) { // Loop thrugh all the players
$player2 = $player->backpack_value;
if ($player2 < 9999999) { // Check the backpack_value
$profiles[] = $player; // Assign the required players to a new array
var_dump($profiles); // Dump the array to browser for debugning
file_put_contents("final." . $timestamp . ".txt", $usernumber);
} //closes if $playtime
} //closes foreach $data
} //closes if !empty
else {
echo $data;
}
}
curl download function:
function curl_download($Url){
// is cURL installed yet?
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
// OK cool - then let's create a new cURL resource handle
$ch = curl_init();
// Now set some options (most are optional)
// Set URL to download
curl_setopt($ch, CURLOPT_URL, $Url);
// Set a referer
curl_setopt($ch, CURLOPT_REFERER, "http://www.google.pl");
// User agent
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla Firefox/1.0");
// Include header in result? (0 = yes, 1 = no)
curl_setopt($ch, CURLOPT_HEADER, 0);
// Should cURL return or print out the data? (true = return, false = print)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
// Download the given URL, and return output
$output = curl_exec($ch);
// Close the cURL resource, and free system resources
curl_close($ch);
return $output;
Output:
array(1) { [0]=> object(stdClass)#102 (6) { ["steamid"]=> string(17) "76561197992831594" ["success"]=> int(1) ["backpack_value"]=> float(47.97) ["backpack_update"]=> int(1369683750) ["name"]=> string(8) "WesFox13" ["notifications"]=> int(0) } } array(1) { [0]=> object(stdClass)#106 (6) { ["steamid"]=> string(17) "76561197992707820" ["success"]=> int(1) ["backpack_value"]=> float(59.78) ["backpack_update"]=> int(1369689171) ["name"]=> string(10) "Alexsutton" ["notifications"]=> int(0) } } array(1) { [0]=> object(stdClass)#98 (6) { ["steamid"]=> string(17) "76561197992146126" ["success"]=> int(1) ["backpack_value"]=> float(36181.59) ["backpack_update"]=> int(1369689000) ["name"]=> string(25) ":HIT: Bobo the Monkey Boy" ["notifications"]=> int(0) } }
My suggestion to you is to use CURL when you want to download something from Web. Moreover use file_get_contents() and file_put_contents() syntax is short and they do the same and they are easier to use.
