尽管您可以轻松找到如何使用PHP处理文件上传的教程，并且有一些功能（手动）可以处理CSV，但是我将发布一些代码，因为几天前我从事一个项目，其中包括一些代码，您可以采用…
HTML：
<table width="600">
<form action="<?PHP echo $_SERVER["PHP_SELF"]; ?>" method="post" enctype="multipart/form-data">
<tr>
<td width="20%">Select file</td>
<td width="80%"><input type="file" name="file" id="file" /></td>
</tr>
<tr>
<td>Submit</td>
<td><input type="submit" name="submit" /></td>
</tr>
</form>
</table>
PHP：
if ( isset($_POST["submit"]) ) {
if ( isset($_FILES["file"])) {
//if there was an error uploading the file
if ($_FILES["file"]["error"] > 0) {
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
}
else {
//Print file details
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";
//if file already exists
if (file_exists("upload/" . $_FILES["file"]["name"])) {
echo $_FILES["file"]["name"] . " already exists. ";
}
else {
//Store file in directory "upload" with the name of "uploaded_file.txt"
$storagename = "uploaded_file.txt";
move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $storagename);
echo "Stored in: " . "upload/" . $_FILES["file"]["name"] . "<br />";
}
}
} else {
echo "No file selected <br />";
}
}
我知道必须有一种更简单的方法来执行此操作，但是我读取了CSV文件并将每个记录的单个单元格存储在二维数组中。
if ( isset($storagename) && $file = fopen( "upload/" . $storagename , r ) ) {
echo "File opened.<br />";
$firstline = fgets ($file, 4096 );
//Gets the number of fields, in CSV-files the names of the fields are mostly given in the first line
$num = strlen($firstline) - strlen(str_replace(";", "", $firstline));
//save the different fields of the firstline in an array called fields
$fields = array();
$fields = explode( ";", $firstline, ($num+1) );
$line = array();
$i = 0;
//CSV: one line is one record and the cells/fields are seperated by ";"
//so $dsatz is an two dimensional array saving the records like this: $dsatz[number of record][number of cell]
while ( $line[$i] = fgets ($file, 4096) ) {
$dsatz[$i] = array();
$dsatz[$i] = explode( ";", $line[$i], ($num+1) );
$i++;
}
echo "<table>";
echo "<tr>";
for ( $k = 0; $k != ($num+1); $k++ ) {
echo "<td>" . $fields[$k] . "</td>";
}
echo "</tr>";
foreach ($dsatz as $key => $number) {
//new table row for every record
echo "<tr>";
foreach ($number as $k => $content) {
//new table cell for every field of the record
echo "<td>" . $content . "</td>";
}
}
echo "</table>";
}
