我试图让这个脚本根据大于/小于脚本输出结果。当我运行这个脚本时，它会输出文本文件中的第一行。关于我遗漏的任何建议？
<?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
?>

最佳答案
好的有两个基本问题。
- fopen 调用需要移出循环。
- 文件调用有一个烦人的习惯，就是保留尾随的换行符。当你建立你的 url 时，你应该使用
trim($usernumber)来摆脱它。
这是关于这两件事的更新。

$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 ^)

print_r($json);
