Question

我在文本区域中有制表符分隔的文本（字符串）。例如，用户只需使用标题将SQL查询中的结果集直接粘贴到此文本区域中。

读取此输入并在php或javascript中转换为数组的理想方式是什么。我最终希望使用json_encode将其转换为json。

这样的事情应该有效：

<?php

if ($_POST) {
    $data = trim($_POST['pastedData']);

    $tabDelimitedLines = explode("\r\n", $data);
    $myArray = Array();

    foreach ($tabDelimitedLines as $lineIndex => $line) {
        $fields = explode("\t", $line);

        foreach ($fields as $fieldIndex => $field) {

            if ($lineIndex == 0) {
                // assuming first line is header info
                $headers[] = $field;
            } else {
                // put the other lines into an array
                // in whatever format you want

                $myArray[$lineIndex - 1][$headers[$fieldIndex]] = $field;
            }
        }
    }

    $json = json_encode($myArray);

    echo "Associative Array in PHP:<br>";
    echo "<pre>";
    var_dump($myArray);
    echo "</pre>";
    echo "JSON:<br>";
    echo $json;
    echo "<br><br>";
}
?>
<html>
<form method="post">
    <label>Paste some Tab Delimited Data with Headers:</label><br>
    <textarea name="pastedData"></textarea><br><br>
    <button type="submit">Submit</button>
</form>
</html>
