Question

这些代码将CSV文件的内容导入数据库。

$databasehost = "localhost";
$databasename = "test";
$databasetable = "sample";
$databaseusername ="test";
$databasepassword = "";
$fieldseparator = ",";
$lineseparator = "\n";
$csvfile = "filename.csv";
$addauto = 0;
$save = 1;
$outputfile = "output.sql";

if(!file_exists($csvfile)) {
    echo "File not found. Make sure you specified the correct path.\n";
    exit;
}

$file = fopen($csvfile,"r");

if(!$file) {
    echo "Error opening data file.\n";
    exit;
}

$size = filesize($csvfile);

if(!$size) {
    echo "File is empty.\n";
    exit;
}

$csvcontent = fread($file,$size);

fclose($file);

$con = @mysql_connect($databasehost,$databaseusername,$databasepassword) or die(mysql_error());
@mysql_select_db($databasename) or die(mysql_error());

$lines = 0;
$queries = "";
$linearray = array();

foreach(split($lineseparator,$csvcontent) as $line) {

    $lines++;

    $line = trim($line," \t");

    $line = str_replace("\r","",$line);

    $line = str_replace("'","\'",$line);

    $linearray = explode($fieldseparator,$line);

    $linemysql = implode("','",$linearray);

    if($addauto)
        $query = "insert into $databasetable values('','$linemysql');";
    else
        $query = "insert into $databasetable values('$linemysql');";

    $queries .= $query . "\n";

    @mysql_query($query);
}

@mysql_close($con);

if($save) {

    if(!is_writable($outputfile)) {
        echo "File is not writable, check permissions.\n";
    }
    else {
        $file2 = fopen($outputfile,"w");

        if(!$file2) {
            echo "Error writing to the output file.\n";
        }
        else {
            fwrite($file2,$queries);
            fclose($file2);
        }
    }

}

echo "Found a total of $lines records in this csv file.\n";

这是它的工作原理。
管理员将收到一个excel电子表格（.xls）文件，并将其保存为.csv文件。该文件的第一行将是excel电子表格的“标题” 示例：姓名，电子邮件，联系电话，国家，地址标题。

因此，在将CSV文件的内容导入数据库之前，我希望跳过第一行。这意味着内容的导入将从CSV文件的第二行开始。

我可以知道我应该编辑哪部分代码以及我应该将其编辑为什么？对不起，因为我是PHP编程的新手。

提前致谢！

Answer 1

这项工作稍有改变。在foreach循环split $csvcontent之前，将结果数组保存到$allLines。然后使用array_shift删除此数组的第一个元素（该函数也返回此元素，但我们在这里不需要它）：

$allLines = split($lineseparator,$csvcontent);
array_shift($allLines); // removes the 1st element

foreach($allLines as $line) {
    [...]

Answer 2

您已经在为每一行使用循环。只需跳过第一次迭代：

$lines = 0;

foreach(split($lineseparator,$csvcontent) as $line) {
    $lines++;

    if($lines > 1){
        $line = trim($line," \t");
        $line = str_replace("\r","",$line);
        $line = str_replace("'","\'",$line);

        $linearray = explode($fieldseparator,$line);

        $linemysql = implode("','",$linearray);

        if($addauto)
            $query = "insert into $databasetable values('','$linemysql');";
        else
            $query = "insert into $databasetable values('$linemysql');";

        $queries .= $query . "\n";

        @mysql_query($query);
    }
}

Answer 3

使用此

$line_array = explode($csvcontent,$lineseparator);
$total_line = count($line_array);
for ($i=1;$i<$total_line;$i++){
    echo $line_array[$i] //it is your line play with this
}
