使用PHP代码和HTML表单将excel（.csv）导入MySQL
我知道还有其他类似的post，但是所有人都build议直接在PHPMyAdmin中将其转换为MySQL（这是完美的，但是我需要通过HTML表单将数据导入到PHP中）。
我想有一个收集文件的HTML表单。 然后将该文件传递给PHP脚本，我想知道是否可以简单地调用一个PHP函数，将逗号分隔的.csv文件转换为MySQL并将其添加到数据库中。
或者是逐行parsing文件并添加每条logging的唯一方法？
我还没有完全testing这个，但我没有看到任何理由不起作用。
<?php if ( isset( $_FILES['userfile'] ) ) { $csv_file = $_FILES['userfile']['tmp_name']; if ( ! is_file( $csv_file ) ) exit('File not found.'); $sql = ''; if (($handle = fopen( $csv_file, "r")) !== FALSE) { while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) { $sql .= "INSERT INTO `table` SET `column0` = '$data[0]', `column1` = '$data[1]', `column2` = '$data[2]'; "; } fclose($handle); } // Insert into database //exit( $sql ); exit( "Complete!" ); } ?> <!DOCTYPE html> <html> <head> <title>CSV to MySQL Via PHP</title> </head> <body> <form enctype="multipart/form-data" method="POST"> <input name="userfile" type="file"> <input type="submit" value="Upload"> </form> </body> </html> 当然，你需要首先validation数据。
我们之前使用过，而且工作得很好。 只要看你的文件和目录权限。 csv_upload_mysql_conf.inc就是数据库链接。 这将一次parsing多个文件，并将其放在一个名为import的表中。 相应地更新。
<?php /* The conf file */ include_once "csv_upload_mysql_conf.inc"; $php_self = $_SERVER['PHP_SELF']; $file_open = 0; $file_exts = array ( 'csv'); #Our Form..... $form = <<< EOFFORM <div align='center' style='border: 1px solid #CCC; background-color: #FAFAFA;padding: 10px; color: #006699; width: 620px; font-family: palatino, verdana, arial, sans-serif;' > <table align=center style='border: 1px solid #CCC; background-color: #FFF;padding: 20px; color: #006699;' cellspacing=1><tbody> <tr><td> <form enctype='multipart/form-data' action='$php_self' method='post'><input type='hidden' name='MAX_FILE_SIZE' value='2000000' /><input type='hidden' name='selected' value='yes' /> Selected file: <input name='userfile[]' type='file' id='userfile[]' multiple='' onChange='makeFileList();' /><br /><br /><input type='submit' value='Upload CSV' /> </td></tr></tbody></table></div> <p> <strong>Files You Selected:</strong> </p> <ul id="fileList"><li>No Files Selected</li></ul> <script type='text/javascript'> function makeFileList() { var input = document.getElementById('userfile[]'); var ul = document.getElementById('fileList'); while (ul.hasChildNodes()) { ul.removeChild(ul.firstChild); } for (var i = 0; i < input.files.length; i++) { var li = document.createElement('li'); li.innerHTML = input.files[i].name; ul.appendChild(li); } if(!ul.hasChildNodes()) { var li = document.createElement('li'); li.innerHTML = 'No Files Selected'; ul.appendChild(li); } } </script> EOFFORM; #End Form; if(!isset($_POST['selected'])){ echo "$form"; } elseif($_POST['selected'] == "yes"){ $uploaddir = 'uploads/'; if(count($_FILES['userfile']['name'])) { foreach ($_FILES['userfile']['name'] as $key => $error) { if ($error == UPLOAD_ERR_OK) { $tmp_name = $_FILES['userfile']['tmp_name'][$key]; $name = $_FILES['userfile']['name'][$key]; $f_type = trim(strtolower(end(explode('.', $name)))); if (!in_array($f_type, $file_exts)) die("Sorry, $f_type files not allowed"); } $uploadfile = $uploaddir . $name; if (! file_exists($uploadfile)) { if (move_uploaded_file($tmp_name, $uploadfile)) { print "File is valid, and was successfully uploaded.

你的代码中的一切都很好，唯一的错误是你没有使用mysql_query将数据插入到表中。 Mysql查询不在脚本中运行。 更正的代码如下…
<?php if ( isset( $_FILES['userfile'] ) ) { $csv_file = $_FILES['userfile']['tmp_name']; if ( ! is_file( $csv_file ) ) exit('File not found.'); $sql = ''; if (($handle = fopen( $csv_file, "r")) !== FALSE) { while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) { $sql = mysql_query("INSERT INTO `table` SET `column0` = '$data[0]', `column1` = '$data[1]', `column2` = '$data[2]'; "); } fclose($handle); } // Insert into database //exit( $sql ); exit( "Complete!" ); } ?> <!DOCTYPE html> <html> <head> <title>CSV to MySQL Via PHP</title> </head> <body> <form enctype="multipart/form-data" method="POST"> <input name="userfile" type="file"> <input type="submit" value="Upload"> </form> </body> </html>
