Php 如何在旧文本文件中整理新行并覆盖到另一个文本文件

我使用php curl接收数据并将其保存到文本文件中。 它会自动刷新并在旧文本上写入数据

因此，我尝试编写一个函数，该函数将排序旧*文本文件中的新*行，并保存新*文本文件。但我崩溃了。我能为它做些什么

旧文本文件

新的旋度数据

应将新行写入新文本文件

---

我不想使用的重复数据。 这里有一个我已经使用过的例子。（请仔细阅读所有行号）

不知道你是否还在寻找答案，但这就是我的答案。如果我正确理解你需要什么，它会完成任务

<?php

error_reporting(E_ALL); ini_set('display_errors', 1);

$newcontent1 = array(); // set new array for future content
$newcontent2 = array(); // set new array for future content

$array1 = array('9999999999', '8888888888', '0000000000', '6666666666', '5555555555', '4444444444', '3333333333', '2222222222', '1111111111');
$array = array(0 => '9999999999', 1 => '8888888888', 2 => '0000000000', 3 => '6666666666', 4 => '5555555555', 5 => '4444444444', 6 => '3333333333', 7 => '2222222222', 8 => '1111111111');
// 2 different output, but it doesn't really matter, just for testing...

echo"Array is :<br />";
print_r($array);
echo"<br /><br />";

echo"File content :<br />";

$file = "test.inc.txt"; // a regulat txt file similar to your 'old text file'
$filec = file_get_contents($file); // get file in a var

print_r($filec);  // only for checking purpose -> remove it when prod mode

echo"<br /><br />";

foreach ($array as $value)
    { // parse array to get the value of each entry
    if( !in_array($value, $newcontent1) ) { array_push($newcontent1, "$value\n"); // we push value to temp array #1
    echo"( value of array entry -> $value )<br />"; // only for checking purpose -> remove it when prod mode
    } else { /* do nothing */ }
    }

echo"<br /><br />";
echo"New temp content 1:<br />";
print_r($newcontent1); // only for checking purpose -> remove it when prod mode
echo"<br /><br />";

$fp = fopen("test.inc.txt","r"); // we open file

    while($line = fgets($fp)) { // parse file data to get each line
        $line = trim($line);
        if( !in_array($line, $array1) ) { array_push($newcontent2, "$line\n"); echo"( value of file line -> $line )<br />"; } else { /* do nothing */ }
    }

echo"<br /><br />";
echo"New temp content 2:<br />";
print_r($newcontent2); // only for checking purpose -> remove it when prod mode
echo"<br /><br />";

echo"New content (sorted ASC):<br />";

// *important part below* -> we combine the 2 temp arrays into one with unique value
$newcontent = array_unique(array_merge($newcontent1, $newcontent2));

sort($newcontent); // rsort($newcontent); for desc order

file_put_contents('output.txt', $newcontent); // we write new content of array to file
// here, you may want to had checking upon creation of new file

print_r($newcontent);

echo"<br /><br />done !";
