海量日志入库
日志目录下有10个日志文件,每个文件压缩后大约60M左右,文件后缀是.gz,如a.gz、b.gz等,文件中行的内容是id=2112112,[email protected],等等其它,
id=2112112,[email protected],等等其它,
id=2112112,[email protected],等等其它,
id=2112112,[email protected],等等其它,
id=2112112,[email protected],等等其它,
id=2112112,[email protected],等等其它,
id=2112112,[email protected],等等其它,

现在是想把这个目录下的每个文件的所有内容insert到数据库中,数据库中的表,是通过email分表的,大约是log_1,log_2,一直到log_1000的分表的,请问下详细的解决方案,比如说怎么样能保证到每个文件在很快的时间内入库,使得脚本执行更有效率
先贴一段代码

<br />	<?php<br />		error_reporting(E_ALL & ~E_NOTICE);<br />		//接收参数<br />		$mysql_host  = XX.XX.XX.XX;<br />		$mysql_user  = XXX;<br />		$mysql_pass  = XX;<br />		$mysql_port  = 3306;<br />		$mysql_db    = 'test';		<br />		$table_pre   = 'log_';<br />		$gz_log_file = a.gz;<br />		//脚本执行日志<br />		$exec_log = '/data_log/record.txt';	<br />	    file_put_contents ($exec_log,'*****************************************START***********************************'."\r\n",FILE_APPEND );<br />		file_put_contents ($exec_log,'param is mysql_host='.$mysql_host.' mysql_user='.$mysql_user.' mysql_pass='.$mysql_pass.' mysql_port='.$mysql_port.' mysql_db='.$mysql_db.' table_pre='.$table_pre.' gz_log_file='.$gz_log_file.' start_time='.date("Y-m-d H:i:s")."\r\n",FILE_APPEND );		<br />		//读日志入库		 <br />		$z_handle = gzopen($gz_log_file,'r');<br />		$time_start = microtime_float();<br />		$mysql_value_ary = array();<br />		//链接数据库<br />		$conn = mysql_connect("$mysql_host:$mysql_port",$mysql_user,$mysql_pass);<br />		if (!$conn) {<br />			file_put_contents ($exec_log,'Could not connect database error, error='.mysql_error()."\r\n",FILE_APPEND );	<br />			exit;<br />		}<br />		$selec_db = mysql_select_db($mysql_db);<br />		if(!$selec_db){<br />			file_put_contents ($exec_log,'select database error, database='.$mysql_db."\r\n",FILE_APPEND );	<br />			exit;<br />		}<br />		while(!gzeof($z_handle)){<br />			$each_gz_line = gzgets($z_handle, 4096);<br />			$line_to_array = explode("\t",$each_gz_line);<br />			//过滤无效日志<br />			if(!empty($line_to_array[3]) && !empty($line_to_array[2]) && !empty($line_to_array[4])){<br />				$insert_value = "('".$line_to_array[3]."','".$line_to_array[2]."','".$line_to_array[1]."','".$line_to_array[4]."','".$line_to_array[0]."')

上面的代码执行起来,很慢,不可忍受,请大牛帮忙
------解决方案--------------------
表类型修改为:InnoDB,然后用事务实施,
还不行的话,换load file
------解决方案--------------------
对于innodb,开事物应该不会更慢,因为就算不开,每一条语句也都是一个事物,所以如果是只开启一个事物,最后commit一次,应该会比每条语句都begin一下,commit一下要快的(但我记得开了事物也不会快多少);但myisam在只有一个插入线程执行,并且表内总数据量比较小的场合下,肯定比innodb要快的,尤其是只有60M数据的环境下

load data infile 绝对会快很多,但你文件得先转换成另一个"xxx \t xxx"的形式,然后再load data infile,应该比一条条插入能快几倍
------解决方案--------------------
load data吧,load进去以后比对一下条数,别搞什么事务。出错几率很低的,即使出错了,删除以后重新导入也快。PS,这数据不叫海量数据。
------解决方案--------------------
不知道为什么要放在数据库中
按你的描述,数据文件展开后,每个在 60*20M左右,甚至更高
你一条一条的插入,不慢才怪呢
------解决方案--------------------
历史数据入库,只是一次性工作。无所谓“效率”
你可以直接将文件导入 text 字段后,再由 update 指令拆分

如果不打算修改日志处理方式,那么将日志增量追加入库也只是一个定期工作(周期至少大于等于1天)
同样也没效率的概念

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
