leetcode用例导入数据库(PHP实现) import leetcode json case into database

<?php
// 换成你自己的json
$str = '{"headers":{"student":["name","continent"]},"rows":{"student":[["Jane","America"],["Pascal","Europe"],["Xi","Asia"],["Jack","America"]]}}';
$a = json_decode($str, true);

if (!isset($a['headers']) || !is_array($a['headers'])) {
    die("invalid json");
}

foreach ($a['headers'] as $dbname => $colnameArr) {
    $colnames = implode(',', $colnameArr);
    $sql = "insert into {$dbname} ({$colnames}) values";
    foreach ($a['rows'][$dbname] as $rowArr) {
        $rows = implode('\',\'', $rowArr);
        $sql .= "('{$rows}'),";
    }
    $sql = rtrim($sql, ',');
    $sql .= ';';
    echo $sql.PHP_EOL;
}

// 本例输出
// insert into student (name,continent) values('Jane','America'),('Pascal','Europe'),('Xi','Asia'),('Jack','America');
