编写PHP文件以从CSV读取并执行SQL查询

本文介绍了编写PHP文件以从CSV读取并执行SQL查询的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我想要PHP脚本以下列格式从CSV文件读取内容



  id,sku 
1,104101
2,105213

共有1486个条目相信,最好使用for循环而不是while!EOF。



之后,我想对名为m118的数据库(catalog catalog_product_entity)执行SQL查询。 / p>

查询将类似UPDATE sku = $ csvSku WHERE id = $ csvId



和MySQL,我不知道从哪里开始编码。

解决方案

fgetcsv可以用来解析CSV文件。



完整的代码如下:

 <?php 
$ fin = fopen('catalog_product_entity.csv','r')或die('cant open file');
$ link = mysql_connect('localhost','m118','pw');
如果(!$ link){
die('Could not connect:'。mysql_error());
}
@mysql_select_db('m118')或die('无法选择数据库');
echo连接成功< br /> \\\
;
while(($ data = fgetcsv($ fin,1000,,))!== FALSE {
$ query =UPDATE catalog_product_entity SET sku ='$ data [1]'WHERE entity_id ='$ data [0]';
mysql_query($ query);
echoRecord updated< br /> \\\
;
}
fclose($ fin);
mysql_close();
?>


I would like a PHP script to read the contents from a CSV file in the following format

id, sku
1,104101
2,105213

there are a total of 1486 entries, I believe that it's better to use a for loop instead of while !EOF.

After that, I would like to perform SQL query on a database named m118, table catalog_product_entity.

The query would be like UPDATE sku=$csvSku WHERE id=$csvId

Being a novice at both PHP and MySQL, I do not know where to start coding.

解决方案

fgetcsv can be used to parse CSV files. mysql_query method could be used to perform MySQL queries.

The complete code is as follows:

<?php
$fin = fopen('catalog_product_entity.csv','r') or die('cant open file');
$link = mysql_connect('localhost', 'm118', 'pw');
If (!$link) {
    die ('Could not connect: ' . mysql_error());
}
@mysql_select_db('m118') or die ('Unable to select database');
echo "Connection succeeded <br />\n";
while (($data=fgetcsv($fin,1000,","))!==FALSE) {
    $query = "UPDATE catalog_product_entity SET sku='$data[1]' WHERE entity_id='$data[0]'";
    mysql_query($query);
    echo "Record updated <br />\n";
    }
fclose($fin);
mysql_close();
?>
