php读取txt文件并将数据插入到数据库,

今天测试一个功能,需要往数据库中插入一些原始数据,PM给了一个txt文件,如何快速的将这个txt文件的内容拆分为所要的数组,然后再插入到数据库中?

serial_number.txt的示例内容:

serial_number.txt:

DM00001A11 0116,
SN00002A11 0116,
AB00003A11 0116,
PV00004A11 0116,
OC00005A11 0116,
IX00006A11 0116,

创建数据表:

create table serial_number(
id int primary key auto_increment not null,
serial_number varchar(50) not null
)ENGINE=InnoDB DEFAULT CHARSET=utf8;

php代码如下:

$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()函数以","为标识符进行拆分

foreach ($contents as $k => $v)//遍历循环
{
  $id = $k;
  $serial_number = $v;
  mysql_query("insert into serial_number (`id`,`serial_number`)
      VALUES('$id','$serial_number')");
}

备注:方法有很多种,我这里是在拆分txt文件为数组后,然后遍历循环得到的数组,每循环一次,往数据库中插入一次。

再给大家分享一个支持大文件导入的

<&#63;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

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

$file = 'sqldata1.txt';

$table = 'cengji';
