php 文本文件操作读取txt文件保存到mysql数据库

实例1、php 读txt文件插入数据库,代码如下:

<?php

$m = mysql_connect('127.0.0.1','root','') or die("Invalid query: " . mysql_error());

mysql_select_db('discuz', $m) or die("Invalid query: " . mysql_error());

$handle = fopen("aa.txt", "r");

while (!feof($handle)) {

 $buffer = ($handle);

 $ss[] = explode('&nbsp', $buffer);



}

//var_dump($ss);

mysql_query("set names 'utf8'",$m);

foreach($ss as $k => $v){

 //addslashes($v);

 //foreach($v as $k = $value){

 //$vv = addslashes($value);

//mysql_query("insert into match_view_test_2 (`kanum`, `username`, `mid`, `rank`, `num` ,`zunum` ,`sex` ,`yucolor` ,`eye` ,`backtime` ,`kongju` ,`fengspeed` )

 //values ('123','123', 20111014060110765 ,1,'123','123','123','123','123','123','123','123')") or die("Invalid query: " . mysql_error());

//}

$kanum = $v[1];

$username = $v[2];

$rank = (int)$v[0];

$num = $v[3];

$zunum = $v[4];

$sex = $v[5];

//echo $sex;

$yucolor = $v[6];

//$eye = $v[7];

$backtime = $v[8].' '.$v[9];

$kongju = $v[10];

$fengspeed = $v[11];

mysql_query("insert into match_view_test (`kanum`, `username`, `mid`, `rank`, `num` ,`zunum` ,`sex` ,`yucolor` ,`eye` ,`backtime` ,`kongju` ,`fengspeed` )

 VALUES('$kanum','$username', 20111014060110765,$rank,'$num','$zunum','$sex','$yucolor','$eye','$backtime','$kongju','$fengspeed')") or die("Invalid query: " . mysql_error());

}

?>

php读取txt文件组成SQL并插入数据库的代码.

先看数据结构,代码如下:

-- 数据表结构：

-- 100000_insert,1000000_insert

CREATE TABLE `100000_insert` (

`id` int(11) NOT NULL AUTO_INCREMENT,

`parentid` int(11) NOT NULL,

`name` varchar(255) DEFAULT NULL,

PRIMARY KEY (`id`)

) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8

100000 （10万）行插入：Insert 100000_line_data use 2.5534288883209 seconds

1000000（100万）行插入：Insert 1000000_line_data use 19.677318811417 seconds

php文件,代码如下:

<?php

/**

* $splitChar 字段分隔符

* $file 数据文件文件名

* $table 数据库表名

* $conn 数据库连接

* $fields 数据对应的列名

* $insertType 插入操作类型，包括INSERT,REPLACE

*/

function loadTxtDataIntoDatabase($splitChar,$file,$table,$conn,$fields=array(),$insertType='INSERT'){

if(emptyempty($fields)) $head = "{$insertType} INTO `{$table}` VALUES('";

else $head = "{$insertType} INTO `{$table}`(`".implode('`,`',$fields)."`) VALUES('"; //数据头

$end = "')";

$sqldata = trim(file_get_contents($file));

if(preg_replace('/s*/i','',$splitChar) == '') {

$splitChar = '/(w+)(s+)/i';

$replace = "$1','";

$specialFunc = 'preg_replace';

}else {

$splitChar = $splitChar;

$replace = "','";

$specialFunc = 'str_replace';

}

//处理数据体，二者顺序不可换，否则空格或Tab分隔符时出错

$sqldata = preg_replace('/(s*)(n+)(s*)/i',''),('',$sqldata); //替换换行

$sqldata = $specialFunc($splitChar,$replace,$sqldata); //替换分隔符

$query = $head.$sqldata.$end; //数据拼接

if(mysql_query($query,$conn)) return array(true);

else {

return array(false,mysql_error($conn),mysql_errno($conn));

}

}

//调用示例1

require 'db.php';

$splitChar = '|'; //竖线

$file = 'sqldata1.txt';

$fields = array('id','parentid','name');

$table = 'cengji';

$result = loadTxtDataIntoDatabase($splitChar,$file,$table,$conn,$fields);

if (array_shift($result)){

echo 'Success! ';

}else {

echo 'Failed!--Error:'.array_shift($result).' ';

}

/*sqlda ta1.txt

//调用示例2

require 'db.php';

$splitChar = ' '; //空格

$file = 'sqldata2.txt';

$fields = array('id','make','model','year');

$table = 'cars';

$result = loadTxtDataIntoDatabase($splitChar,$file,$table,$conn,$fields);

}

) ENGINE=InnoDB AUTO_INCREMENT=14 DEFAULT CHARSET=utf8

*/

//调用示例3

require 'db.php';

$splitChar = ' '; //Tab

$file = 'sqldata3.txt';

$fields = array('id','make','model','year');

$table = 'cars';

$insertType = 'REPLACE';

$result = loadTxtDataIntoDatabase($splitChar,$file,$table,$conn,$fields,$insertType);

if (array_shift($result)){

echo 'Success! ';

}else {

echo 'Failed!--Error:'.array_shift($result).' ';

}

/* sqldata3.txt

//调用示例3

require 'db.php';

$splitChar = ' '; //Tab

$file = 'sqldata3.txt';

$fields = array('id','value');

$table = 'notExist'; //不存在表

$result = loadTxtDataIntoDatabase($splitChar,$file,$table,$conn,$fields);

if (array_shift($result)){

echo 'Success! ';

}else {

echo 'Failed!--Error:'.array_shift($result).' ';

}

//附：db.php

/* //注释这一行可全部释放

?>

<?php

static $connect = null;

static $table = 'jilian';

if(!isset($connect)) {

$connect = mysql_connect("localhost","root","");

if(!$connect) {

$connect = mysql_connect("localhost","Zjmainstay","");

}

if(!$connect) {

die('Can not connect to database.Fatal error handle by /test/db.php');

}

mysql_select_db("test",$connect);

mysql_query("SET NAMES utf8",$connect);

$conn = &$connect;

$db = &$connect;

}

?>

如果出现MySQL server has gone away 是因为导入数据包过大,导入mysql挂机了,我们解决方法是修改my.ini/my.cnf max_allowed_packet=20M.
