Question

我正在尝试创建2个类，以封装这些文本文件，Customer.txt和Orders.txt。客户我需要将每行读入每行文本的单独数组实例，我该怎么做？另外，我是否必须对文本文件中的逗号做些什么？

我知道我需要使用fopen，只是不确定如何去做。

这是我到目前为止所尝试过的。

<?php



class readOrders{

$array_of_lines = fopen("orders.txt", 'r') or die("Failed to create file");
  foreach($array_of_lines as $line) {
 $pieces_of_line = explode(',', $line); 

}

class readCustomers{
$array_of_more_lines = fopen("customers.txt", 'r') or die("Failed to create file");
  foreach($array_of_more_lines as $line) {
 $pieces_of_line = explode(',', $line);

}


?>

这是我的文本文件

我认为 fgetcsv 在这里很有用，例如来自php-doc：

<?php
$row = 1;
if (($handle = fopen("test.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);
}
?>
