跳过CSV文件的第一行

Question

我正在尝试导入CSV文件.由于我们使用的程序,第一行基本上是我想要跳过的所有标题,因为我已经将自己的标题放在via HTML中.如何让代码跳过CSV的第一行？(strpos命令用于切断所有行中的第一个字段.)

<?php
$row = 1;
if (($handle = fopen("ptt.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
    $num = count($data);
           $row++;
    for ($c=0; $c < $num; $c++) {
    if(strpos($data[$c], 'Finished') !== false) {
    $c++;
echo "<TR> <TD nowrap>" . $data[$c] . "</ TD>"; }
    Else{
        echo "<TD nowrap>" .  $data[$c] . "</ TD>";
        }
    }
}
fclose($handle);
}
?>

Answer 1

Rather than using if condition for checking whether it is the first row, a better solution is to just add an extra line of code before the line from where the while loop starts as shown below :

....
.....
fgetcsv($handle);//Adding this line will skip the reading of th first line from the csv file and the reading process will begin from the second line onwards
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
.......
.......

It is just as simple......

无论如何,当您跟踪行号时,您可以使用continue跳过第一行的其余循环.

例如,在while循环的开头添加它(就在上面$num = count($data)):

if($row == 1){ $row++; continue; }

还有其他方法可以做到这一点,但只要确保当你继续,$row仍在增加或你将获得无限循环!
