问题描述

预先感谢您的时间/帮助。我是新手学习php，所以请记住这一点。

Thank you in advance for your time/help. I'm a newbie learning php, so please keep that in mind.

第一个问题
我需要一个读取csv文件的php脚本。

1st Question I need a php script that reads a csv file.

第二个问题
如何回显该文件中的特定单元格（行和列/列）

2nd Question How do I echo a specific cell (row and row/column) in that file

我发现这个脚本在类似的回复，脚本读取整个文件完美，但我只想选择一个特定的单元格/值在该csv文件。那么如何回显一个特定的行或一个行和列。

I found this script on a similar reply, the script reads the whole file perfectly, but I only want to select a specific cell/value on that csv file. So how do I echo a specific row or a row and column.

$row = 1;
if (($handle = fopen("1.csv", "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $num = count($data);
        echo "<p> $num fields in line $row: <br /></p>\n";
        $row++;
        for ($c=0; $c < $num; $c++) {
            echo $data[$c] . "<br />\n";
        }
    }
    fclose($handle);
}

推荐答案

case，最好的方法是在php中做一个多维数组。

If you need to select several cases, the best way is to make a multi-dimensional array in php. Otherwise, just throw a few counters into your while loops and done.

$row = 1;
$mycsvfile = array(); //define the main array.
if (($handle = fopen("1.csv", "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $num = count($data);
        echo "<p> $num fields in line $row: <br /></p>\n";
        $row++;
        for ($c=0; $c < $num; $c++) {
            echo $data[$c] . "<br />\n";
        }
        $mycsvfile[] = $data; //add the row to the main array.
    }
    fclose($handle);
}

echo $mycsvfile[3][1]; //prints the 4th row, second column.
