如何在MySQL + PHP中将所有列作为行

Question

I have a table in MySQL DB like this one:

> NAME     |   VALUE
>--------------------
> Jon      |    0.2
> Galson   |    0.34
> Sam      |    0.5

I need to display this table in my web app with something like this:

> NAME    |     Jon     |   Galson   |    Sam
> VALUE   |     0.2     |    0.34    |    0.5

I just want to convert database column into rows using MYSQL + PHP only for display purpose.

Answer 1

You should not be doing this using a (probably complex) SQL query. Instead rely on HTML/CSS for this:

Assuming

$data = [{name: 'Jon', value: 0.2}, {name: 'Galson', value: 0.34}, {name: 'Sam', value: 0.5}]

you could

foreach($data as $person) {
    echo '<div class="person">';
    echo '<div class="name">' . $person->name . '</div>';
    echo '<div class="value">' . $person->value . '</div>';
    echo '</div>';
}

and

.person {
    float: left; 
}

Also don't , never ever, under any circumstances, build HTML like that. Use some kind of templates.

You should check out @Sergiu Paraschiv answer. What you definitely do not want to do is use the deprecated mysql_db_query() . Alternatively try something like this:

<?php
$db = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password');
$stmt = $db->query('SELECT name, value FROM table');
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);

$output = [];

foreach($results as $row) {
    $output[$row['name']] = $row['value'];
}
print_r($output);
