在查阅 服务器上日志文件的时候的，对于小的日志文件 可以直接打开浏览即可，但是对于较大文件 几十 上百兆的，查找日志就没有那么方便了。
特别是查找某一时间段内的日志，对于其他无关内容是，如果全都下载是十分浪费时间的行为，所以就有了本文这段代码。
用于在大的日志文件中查找指定时间段内的 日志内容并返回。
<?php
// 在 error.txt 文件内提取 2024-03-09 0:00:00 至 2024-03-09 23:59:59 时间段内的 php 错误日志
print_r(_filterLogs('error.txt', '2024-03-09 0:00:00', '2024-03-09 23:59:59'));
/**

* @param string $file 日志文件路径
* @param string|int $start 开始时间 日期字符串 或 者时间戳
* @param string|int $end 结束时间 格式同上
* @param string $rule 日期匹配规则

function _filterLogs($file, $start, $end, $rule = '/^[ \d\.\-]*?\[(?<date>[^\]]+)/'){
if(!is_file($file)){
throw new \Exception('文件不存在');
}
$start = is_numeric($start) ? floatval($start) : strtotime($start);
$end = is_numeric($end) ? floatval($end) : strtotime($end);
if($start > 1 && $end > 1 && $start <= $end){
if(is_string($rule) && preg_match('/\(?<(date|time)>/', $rule)){
// 存储最终结果
$content = '';
$number = 0;
// 存储 文本块

// 在时间段内

$date = '';
foreach (_filterLogsYieldFile($file) as $line) {
if(preg_match($rule, $line, $time)){
if($block !== '' && $in_times){
$content .= $date . $block;
$number ++;
}
$block = "$line\n";
if(isset($time['date'])){

if($time && $time > 1){
$in_times = $time >= $start && $time <= $end;
// $date = date('Y-m-d H:i:s', $time);
continue;
}else{
throw new \Exception('解析时间失败');
}
}

}
}
return [
$number,
$content,

}else{
throw new \Exception('规则不正确');
}
}else{
throw new \Exception('开始 或 结束时间不正确');
}
}
// 使用迭代器读取文件
function _filterLogsYieldFile($path) {
$handle = fopen($path, "r");
while(!feof($handle)) {
yield trim(fgets($handle));
}
fclose($handle);
}
执行后正常将会返回 error.txt 自定时间段内的日志信息
