或者生成一個(gè)1.sql文件,再把它導(dǎo)入mysql;
第一步,讀取txt的文件。假設(shè)為a.txt
$content = file_get_content('a.txt'); //讀取文件內(nèi)容存入變量。
第二步,存入數(shù)據(jù)庫
mysql_query("insert 表名 (字段名) values('".$content."'));
Ps:文件是上傳的,上傳后的臨時(shí)文件名是:$_FILE['tmp_name']
$myfile = fopen("webdictionary.txt", "r") or die("Unable to open file!");
$txt= fread($myfile,filesize("webdictionary.txt"));
fclose($myfile);
fopen讀取txt文件的內(nèi)容,返回字符串,把它存入一個(gè)變量,再把變量值存入數(shù)據(jù)庫。可以看看這個(gè)函數(shù)
serial_number.txt的示例內(nèi)容:
serial_number.txt:
DM00001A11 0116,
SN00002A11 0116,
AB00003A11 0116,
PV00004A11 0116,
OC00005A11 0116,
IX00006A11 0116,
創(chuàng)建數(shù)據(jù)表:
create table serial_number(
id int primary key auto_increment not null,
serial_number varchar(50) not null
)ENGINE=InnoDB DEFAULT CHARSET=utf8;
php代碼如下:
$conn = mysql_connect('127.0.0.1','root','') or die("Invalid query: " . mysql_error());
mysql_select_db('test', $conn) or die("Invalid query: " . mysql_error());
$content = file_get_contents("serial_number.txt");
$contents= explode(",",$content);//explode()函數(shù)以","為標(biāo)識(shí)符進(jìn)行拆分
foreach ($contents as $k = $v)//遍歷循環(huán)
{
$id = $k;
$serial_number = $v;
mysql_query("insert into serial_number (`id`,`serial_number`)
VALUES('$id','$serial_number')");
}
備注:方法有很多種,我這里是在拆分txt文件為數(shù)組后,然后遍歷循環(huán)得到的數(shù)組,每循環(huán)一次,往數(shù)據(jù)庫中插入一次。
再給大家分享一個(gè)支持大文件導(dǎo)入的

讀取的是服務(wù)器上硬盤C區(qū)中的123.txt
而不是訪問者電腦的硬盤上的文件!
無論什么服務(wù)器端腳本, 在用戶未上傳本地文件的情況下, 都是不可能讀取到客戶端上的文件的!
