如何使用php格式化上面的json数据
答案 0 :(得分:2)
使用
json_decode($ jsonObject,true);
此函数会将您的json数据转换为php数组。但是你编写的代码似乎非常低效,你不应该在foreach()变量中运行你的查询,你应该这样使用。
<?php
try {
$dbh = new PDO('mysql:host=localhost;dbname=$db', $user, $pass);
$result = $dbh->query('SELECT * FROM `jos_jea_towns` LIMIT 0, 500 ');
foreach($result as $row) {
echo '<pre>';
print_r($row);
echo '</pre>';
//echo '<pre>' . json_encode($row, JSON_PRETTY_PRINT).'</pre>';
}
$dbh = null;
} catch (PDOException $e) {
print "Error!: " . $e->getMessage() . "<br/>";
die();
}
?>
