我想要使用 php 的以下功能
I want the following functionality using php
我有一个 csv 文件.每个文件对应我数据库中的一行
I have a csv file. Each file corresponds to a row in my database
有一个 html 表单可以让我选择 csv 文件.
There is a html form that will allow me to choose the csv file.
然后,一旦表单提交,我必须解析 csv 文件并将数据相应地插入到数据库中
Then once the form is submitted, I must parse the csv file and insert data into the db accordingly
我该怎么做呢?
读取 CSV 文件通常可以使用 fgetcsv
函数 (根据您的 CSV 文件类型,您可能需要指定分隔符、分隔符...作为参数)
Reading a CSV file can generally be done using the fgetcsv
function (depending on your kind of CSV file, you might have to specify the delimiter, separator, ... as parameters)
这意味着逐行浏览文件不会比这样更难:
Which means that going through you file line by line would not be much harder than something like this :
$f = fopen('/path/to/file', 'r');
if ($f) {
while ($line = fgetcsv($f)) { // You might need to specify more parameters
// deal with $line.
// $line[0] is the first column of the file
// $line[1] is the second column
// ...
}
fclose($f);
} else {
// error
}
(未测试,但在 fgetcsv 的手册页上给出的示例应该可以帮助您入门)
(Not tested, but example given on the manual page of fgetcsv should help you get started)
当然,您必须获得上传文件的正确路径——参见 $_FILE
超全局,以及关于 处理文件上传,了解更多信息.
Of course, you'll have to get the correct path to the uploaded file -- see the $_FILE
superglobal, and the section on Handling file uploads, for more informations about that.
而且,要将数据保存到您的数据库中,您必须使用适合您的数据库引擎的 API——如果使用 MySQL,您应该使用:
And, to save the data into your database, you'll have to use the API which suits your DB engine -- if using MySQL, you should use either :
