Php 从数组中查找并组合两个字符串

我有一个包含以下行的文本文件，我已将其读入名为$pirep的数组中

06:36  Block to Block Duratio
n: 07:37 
06:36  Final Fuel: 1044 Lbls

我已经编写了查找“块到块持续时间”的代码，并将随后的时间记录到数据库中。问题是代码无法找到字符串，因为文本文件被分解成1KB块，恰好正好落在我的搜索字符串的中间。

我知道如何使用str_replace（PHP_EOL'）连接这两个字符串，如果每次都在同一个地方写入数据，那就太好了，但事实并非如此

是否有一种方法可以识别每行之前的时间模式并合并行，直到找到该模式的下一个匹配项，以便最终结果如下所示：

06:36  Block to Block Duration: 07:37
06:36  Final Fuel: 1044 Lbls

这只是我的第二个问题，我真的不希望这件事让任何人感到不安。谢谢

明白了！这是有效的

if($i>=15) {
if(substr($line,2,1)!=":") {
    $first_line=str_replace(PHP_EOL,"",$pirep[$i-1]);
    $line=$first_line.$pirep[$i];
    echo $line."<br>";
    }
}

如果（$i>=15）{
if（substr（$line，2,1）！=“：”）{
$first_line=str_replace（PHP_EOL，“，$pirep[$i-1]）；
$line=$first_line.$pirep[$i]；
回音$line.“
”；
}
}

您当前的代码是什么样子的？您能否为文本数据制定规则，以便我们了解任何给定的数据行是如何组成的？最大文件大小是多少？如果不太长，将整个文件合并成一个字符串并搜索它可能同样简单。同样，在最后，您仍然希望将文本文件的所有行与下一行连接起来？我感谢您的回复！我编辑了我的原始问题，包括我迄今为止编写的php脚本和一份给我带来问题的文本文件副本。请原谅我脚本中的任何新手错误，因为我是自学成才的。如果你看一下文本文件，你会发现，在每1KB的数据中，用于写入文本文件的可执行文件都会写入一行末尾，不管它在哪里。这会导致您在以23:59、02:44、05:14开头的行和“06:36块到块的持续时间”的行上看到的结果。理想的解决方案是删除该换行符，并将该行与该换行符后面的一行合并，从而显示“06:36块到块的持续时间：07:37”
