好的,我在这里遇到了一些严重的问题.我是这个网站的新手,也是处理通过
PHP导入CSV数据的新手,但我不是编程的新手.
目前,我正在建立一个客户关系经理.我需要创建一个脚本来导入一个文件,该文件将使用潜在客户填充数据库.这里的主要问题是,主要数据包括该公司的公司和员工.此外,还从主表中分离出一些其他表,例如计费信息.
function mapData($file) {
// Open the Text File
$fd = fopen($file,"r");
// Return FALSE if file not found
if(!$fd) {
return FALSE;
}
// Get the First Two Lines
$first = 0;
$data = array();
while(!feof($fd)) {
if($first == 0) {
$cols = fgetcsv($fd,4096);
$data['cols'] = array();
if(is_array($cols) && count($cols)) {
foreach($cols as $col) {
if(!$col) {
continue;
}
$data['cols'][] = $col;
}
}
if(empty($data['cols'])) {
return array();
}
$first++;
continue;
}
else {
$data['first'] = fgetcsv($fd,4096);
break;
}
}
fclose($fd);
// Return Data
return $data;
}
上述脚本仅在CodeIgniter将文件移动到工作目录后激活.到目前为止我已经知道文件名是什么了.该文件进入并返回列列表和第一行.任何空列都将被忽略.
在此之后,进程将传递给映射脚本.完成映射并按下“导入”后,将加载此代码.
function importLeads($file,$map) {
// Open the Text File
if(!file_exists($file)) {
return false;

现在,据我所知,脚本运行得非常好.实际的代码本身并没有错.问题是,在大约400-500行之后,脚本就会停止.我没有收到错误,但没有处理更多代码.
我知道这是因为我之后有代码应该通过AJAX返回重定向页面.但是,我在importLeads函数中的循环之后没有任何内容加载.
我不确定如何使这个脚本更有效…我很肯定它超时,但我不知道如何使它更有效地运行.我需要这个脚本来单独处理上面的所有信息.我有各种各样的表连接在一起,这个导入脚本必须以不同的方式设置所有内容.
我和我的客户谈过这个项目.当我将它放到大约400行时,此脚本可以正常工作.他有很多这些CSV文件,大约75,000行.我导入的是较小的一个,只有大约1,200行.
我已经尝试过研究其他方法,例如MysqL的导入脚本,但是我不能这样做,因为这个脚本必须将数据导入到单独的表中,并且必须首先检查现有数据.我也应该使用导入的信息更新所有空字段,但这会使情况更糟.
如果有人知道更有效的方法,将非常感激.我试着尽可能详细.值得注意的是,我会提到我正在使用CodeIgniter,但是如果有一种更有效的方式不使用CodeIgniter我会接受它(尽管我仍然可以将它放入CI模型中).
我编写了PHP脚本来批量加载Stack Overflow数据转储发布的数据.我导入了数百万行,并且不需要那么长时间.
以下是一些提示：
>不要依赖自动提交.为每一行启动和提交事务的开销是巨大的.使用显式事务,并在每1000行(或更多行)之后提交.
>使用准备好的陈述.由于您基本上执行相同的插入数千次,因此可以在开始循环之前准备每个插入,然后在循环期间执行,将值作为参数传递.我不知道如何使用CodeIgniter的数据库库,你必须弄明白.
>调整MysqL以进行导入.增加缓存缓冲区等.有关更多信息,请参见Speed of INSERT Statements.>使用LOAD DATA INFILE.如果可能的话.它比使用INSERT逐行加载数据快20倍.我明白,如果你不能,因为你需要获得最后一个插入ID等等.但在大多数情况下,即使您读取CSV文件,重新排列并将其写入多个临时CSV文件,数据加载仍然比使用INSERT更快.>离线.不要在Web请求期间运行长时间运行的任务. PHP请求的时间限制将终止作业,如果不是今天,那么下周二当作业延长10％时.而是将Web请求队列作为作业,然后将控制权返回给用户.您应该将数据导入作为服务器进程运行,并定期允许用户瞥见进度.例如,一种廉价的方法是让你的导入脚本输出“.”到临时文件,然后用户可以请求查看临时文件并继续在其浏览器中重新加载.如果你想获得幻想,可以使用Ajax做点什么.
