用PHP插入文本文件到MySQL

Question

我想用PHP加載.txt文件中的數據，但每次都失敗。 我試圖將文本文件轉換爲CSV，但即使在那裏我也失敗了。 我的文本文件包含這樣的內容：

0001 

120PCS LED MOVING HEAD LIGHT 

TECHNICAL PARAMETER 
Voltage: AC90V-120V or 200V-240V 50-60HZ 
Power consumption:400W 
Light source:120PCS 1W or 3W LED 
(R:30pcs?G:30pcs,B:30psc,W:30pcs) 
Control mode:12HS 
Operation mode: master-slave, auto movement, 
Sound control: DMX 512 
Each led source has an expectancy over 50000 to 100000 hours in theory 
Optical len angle:15 degrees 
Level scanning:540 degrees Vertical scanning 
270 degrees, speed adjustable 
Indefinite RGBW color mixing system 
LCD display adopted 
Product size:512*402*555mm 
N.W:19kg G.W:21kg 

0002 

LED 108PCS MOVING HEAD LIGHT 

TECHNICAL PARAMETER 
Voltage:AC100V-240V ,50/60HZ 
Power consumption:306W 
Light source:108pcs of 1/3W LED 
Operation mode master-slave, sound control, 
auto movement,DMX512 
Control channel:11Hs 
Level scanning angle:540 degrees 
Vertical scanning angle:270degrees 
Quick electronic dimmer, strobe from 1 to 20 times/second 
Smooth RGB mixing system & 
Rainbow effect(can add white) 
Beam angle:15 degrees 
Package size :420*330*550mm 
N.W:10kg G.W:13kg 

我試着使用：

<?php 
$handle = @fopen("data.txt", "r"); 
$conn = mysql_connect("localhost","root",""); 
mysql_select_db("mytext",$conn); 
while (!feof($handle)) // Loop til end of file. 
{ 
$buffer = fgets($handle, 4096); 
    // Read a line. 
list($a,$b,$c)=explode("|",$buffer); 
//Separate string by the means of | 
echo $a."-".$b."-".$c."<br>"; 
$sql = "INSERT INTO data_table (id, name, age) VALUES('".$a."','".$b."','".$c."')"; 
mysql_query($sql,$conn) or die(mysql_error()); 
} 
?> 

但我無法弄清楚如何很好地插入。

value a = 0001 
value b = 120PCS LED MOVING HEAD LIGHT 
value c = Technicalparameter etc etc etc 

value a = 0002 
value b = LED 108PCS MOVING HEAD LIGHT 
value c = Technicalparameter etc etc etc 

我對分隔符有問題。

假設您的輸入文件如上所示，下面的代碼將工作。那就是：

• 包含每個記錄
• 場3場在文件由空行文件整除分離

• 字段數由3

  <?php 
      /* For simplicity in this example, I will assume the db table 
      * conforms to the following schema: 
      * 
      * CREATE TABLE products(
      * id VARCHAR(5), 
      * item VARCHAR(100), 
      * item_details TEXT 
      *); 
      */ 
  
      /* Make the db connection */ 
      $link = mysql_connect('localhost', 'mysql_user', 'user_pwd'); 
      if (!$link) { 
       die('Could not connect to db.'); 
      } 
  
      // set the db. 
      $db_selected = mysql_select_db('test', $link);

      $delimiter = "$lec$lec";

      $contentArray = explode($delimiter, $fileContents);

       $id = mysql_real_escape_string($contentArray[$i]); 
       $item = mysql_real_escape_string($contentArray[$i+1]); 
       $item_details = mysql_real_escape_string($contentArray[$i+2]); 
       $records .= "('$id', '$item', '$item_details'), "; 
       echo("id = $id<br> 
         item = $item<br> 
         item_details = $item_details<br> 
         <hr>"); 
      } 
  
      /* Now trim the ending comma and space from string of records. */ 
      $records = substr($records, 0, -2); 
      //exit($records); 
  
      /* Build and execute the SQL INSERT query. */ 
      $query = "INSERT INTO products (id, item, item_details) 
        VALUES $records"; 
      $result = mysql_query($query); 
  
      /* Check for db error. */ 
      if(!$result) echo("Query Error! Process aborted."); 
  ?>

您正在嘗試explode每條線與|字符，但我沒有看到任何|在文中！ PHP代碼看起來OK（未測試）。這是需要工作的文本輸入。
