Ich habe forloop für FAQ, wo Anzeige alle FAQ-Werte und ich FAQ Kategorie, aber in separaten Tabelle.

Ich möchte die FAQ-Kategorie anzeigen. oben verwende ich die verschachtelte for-Schleife, aber mit einem Fehler enden.

Ich möchte die verschachtelte for-Schleife mit in der for-Schleife für die Anzeige aller Kategorie anzeigen. wie diese

Answer 1

zu erreichen Verwenden Sie

<?php foreach ($faq as $faq): ?> 

Versuchen Sie eine andere Taste, wie

<?php foreach ($faq as $f): ?> 

Answer 2

Versuchen

foreach ($faq as $intKey=>$strValue) 

so $ strValue ist die Elemente, wie Sie

wollen

Answer 3

Falsch Verwendung, Schlüssel und Werte können nicht identisch sein.

<?php foreach ($faq as $faq): ?> 
<?php foreach ($category as $category){ ?> 

zum Beispiel

$arr = array(1, 2, 3, 4); 

foreach ($arr as &$value) { 
    $value = $value * 2; 
}
