csv 文件导入到 mysql 数据库使用 php 面临导入错误

Question

正在使用 php 脚本在 phpmyadmim 中导入 CVS 文件（Microsoft Office Excel 逗号分隔值文件 (.csv)）。当我导入 CSV 文件时，它没有正确导入到数据库中。行以“,”结束请建议我如何让它终止行 "auto"，我附上示例文件。

我只是与此共享 CSV 文件 link http://www.soniinfotech.com/product-data.csv

在 aome 建议和更正之后，我遇到了另一个问题。实际 cvs 文件大小为 106700 行，它插入了 81499 行。我有几次插入文件，但它的总行数是 81499 插入。请帮助我解决这个问题，我如何将所有行插入数据库。

Answer 1

您提供的代码存在一些问题：

1。不指定最大线宽

仅当您知道长度参数（第二个参数）足以阅读整行时，才将长度参数（第二个参数）指定为 fgetcsv()。否则只需使用 0（零）让 PHP 自动检测换行符。（它甚至会智能地使用实际换行的新行，避免在 CSV 引用值中可能发生的换行）

fgetcsv($csvfile, 0, ",")

2。在插入 DB

之前转义您的字符串

当您将字符串值插入 MySQL 时，您需要正确地转义它们。如果您不这样做，并且字符串包含引号，它可能会破坏您的 SQL 查询，导致插入失败。

使用非转义字符串也会带来 SQL-injection attack.

的风险

要转义字符串，请使用 mysqli_real_escape_string() 函数。

即：

$field_csv['productId'] = mysqli_real_escape_string( $mysqli, $csv_data[0] );  // 1
$field_csv['title'] = mysqli_real_escape_string( $mysqli, $csv_data[1] ); // 2
$field_csv['description'] = mysqli_real_escape_string( $mysqli, $csv_data[2] ); // 3
$field_csv['imageUrlStr'] = mysqli_real_escape_string( $mysqli, $csv_data[3] );  // 4
// ... etc.

3。使用 mysqli_error() 调试 SQL 查询可能出现的错误

如果您不检查 SQL 查询中的错误，您就是运行盲人。如果发生错误，您甚至可能不会注意到它。

始终检查 mysqli_query(). (it will return boolean FALSE on failed query) and print out the error, using mysqli_error()

的 return 值

if ( ! mysqli_query( $mysqli,$query ) ) {
  printf( "Error: %s\n", mysqli_error( $mysqli ) );
}
