Question

我的代码是

<?php /*My PHP/JSON 
              Code */
$con = mysql_connect("localhost","root","root");/*establish connection*/
if (!$con)
{
die('Could not connect: ' . mysql_error());
}

$con = mysql_connect("localhost","root","root");

mysql_select_db("TEACHER", $con);
$result = mysql_query("SELECT * from TEACHER") or die('Could not query');
$json = array();
if(mysql_num_rows($result)){
        $row=mysql_fetch_assoc($result);
    while($row=mysql_fetch_row($result)){
        $test_data[]=$row;
    }
    $json['employees']=$test_data;
}
$encoded = json_encode($json);
echo $encoded;
echo "<br />";
echo "<br />";
echo var_dump(json_decode($encoded));
echo "<br />";
echo "<br />";
$tmp_array = json_decode($encoded);

echo "List of Teachers";
echo "<br />";
echo "---------------------------------";
echo "<br />";
foreach($tmp_array->employees as $item)
{
    echo $item[0] . " " . $item[1];
    echo "<br />";
}
mysql_close($con);
?>

我的代码输出是

Answer 1

首先解码，使用json_decode

    $tmp_array = json_decode($data);

2- for loop

    foreach($tmp_array->employees as $item)
    {
        echo $item[0] . "/" . $item[1] . "/" . $item[2];
    }

代码脑测试。：）

Answer 2

$decoded = json_decode($json);
foreach ($decoded->employees as $emp)
  printf("%s %s\n", $emp[0], $emp[1]);
