[英]while loop with if statement not working properly
hi i have the following while loop : 嗨,我有以下while循环:
while ($row = mysqli_fetch_array($result2)){
$elem_filho = $row['itempt_dim'];
$marcas = "{name: " . "'" . $elem_filho . "'" . ", color: " . "'" . $cor_alea . "'" . ", size: 1";
if (mysqli_num_rows($result2)) {
$dif = "},";
}
else {
$dif = "}]";
}
$vlk = $marcas . $dif;
print_r($vlk);
}
the thing is i had similar code and it worked this way, but the output is alway }, and i want the last item of the query to end with }] i can't see what i am doing wrong 事情是我有类似的代码,它以这种方式工作,但是输出始终是},并且我希望查询的最后一项以}结尾]我看不到我在做什么
thanks in advance 提前致谢
With json_encode
you code is simplified to: 使用
json_encode
您的代码可简化为:
$vlk = [];
while ($row = mysqli_fetch_array($result2)) {
$vlk[] = [
'name' => $row['itempt_dim'],
'color' => $cor_alea,
'size' => 1,
];
}
print_r(json_encode($vlk));
