Array Formatierung Drucktisch

Question

Ich habe Schleife, so etwas wie:

foreach($cars as $car){ 
    $html .= $car[name]; 
    $html .= $car[color]; 
    $html .= $car[doors]; 
} 

Es es wie eine Tabelle drucken:

Mercedes | red | 3 
Mercedes | blue | 3 
Mercedes | red | 5 
Ford | green | 4 
Ford | green | 5 

Wie drucken Sie es mögen:

Mercedes 
red | 3 
blue | 3 
red | 5 

Ford 
green | 4 
green | 5 

Bitte geben Sie mir ein paar Tipps.

Answer 1

in der Bahn zu erreichen ich dies gefunden:

`foreach($features as $key => $feature){ 
{ 
$html .= '<table style=" margin:0 20px; border:0;">'; 
$_features = $feature['features']; 
{ 
if(!isset($features[$key-1]) || $feature['groupname'] != $features[$key-1]  ['groupname']) 
$html .= '<tr><td colspan="2">'.$feature['groupname'].'</td></tr>'; 
$html .= '<tr>'; 
$html .= '<td style="padding: 3px 5px 3px 0;width:230px;float:  left;background-color: #F4F4F6; font-family: Tahoma, Geneva, sans-serif; font- size:16px; text-align: right;">'.$feature['name'].' </td>'; 
$html .= '<td style="padding: 3px 0px 3px 10px;width: 400px;float: left;background-color:#ECECEC; font-family: Tahoma, Geneva, sans-serif; font-size:16px; font-weight: bold;text-align: left;">'.$feature['value'].'</td>'; 
$html .= '</tr>'; 
} 
$html .= '</table>'; 
}` 

Es half mir, mein Problem zu lösen.

Answer 2

Alles, was Sie tun müssen, ist sich an den Namen des letzten Autos zu erinnern, und wenn sie sich ändern, geben Sie den Namen des Autos aus.

$last_car = NULL; 
foreach($cars as $car){ 
    if ($last_car != $car['name']) { 
     $html .= $car[name] . '<br>'; 
     $last_car = $car['name']; 
    } 
    $html .= $car[color] . '|'; 
    $html .= $car[doors] . '<br>'; 
} 

Answer 3

Sie können dies versuchen:

$temps = array(); 
$html = ''; 
$i = 0; 
foreach($cars as $car){ 
    $temps[$car['name']][$i]['color'] = $car['color']; 
    $temps[$car['name']][$i]['doors'] = $car['doors']; 
    $i++; 
} 
foreach($temps as $tmp=>$val){ 
     $html .= $tmp."<br>"; 
    foreach($val as $v){ 
     $html .= $v['color']." | "; 
     $html .= $v['doors']; 
     $html .= '<br>'; 
    } 
} 
print $html;

Let Blick auf unsere ursprünglichen Anordnung von Autos

Array(
[0] => Array 
    (
     [name] => Ford 
     [color] => Red 
     [door] => 3 
    ) 

[1] => Array 
    (
     [name] => Toyota 
     [color] => Yellow 
     [door] => 4 
    ) 

[2] => Array 
    (
     [name] => Toyota 
     [color] => White 
     [door] => 3 
    ) 

[3] => Array 
    (
     [name] => Toyota 
     [color] => Yellow 
     [door] => 3 
    ) 

[4] => Array 
    (
     [name] => Mercedes 
     [color] => Black 
     [door] => 4 
    ) 

[5] => Array 
    (
     [name] => Lexus 
     [color] => Yellow 
     [door] => 4 
    ) 

[6] => Array 
    (
     [name] => Mercedes 
     [color] => White 
     [door] => 2 
    ) 

[7] => Array 
    (
     [name] => Mercedes 
     [color] => Black 
     [door] => 4 
    ) 

[8] => Array 
    (
     [name] => Mercedes 
     [color] => Black 
     [door] => 4 
    ) 

[9] => Array 
    (
     [name] => Toyota 
     [color] => Black 
     [door] => 3 
    ) 

[10] => Array 
    (
     [name] => Toyota 
     [color] => White 
     [door] => 3 
    ) 

)
