    } 
}

J'essaie de supprimer une entrée en fonction de « id ». Donc, étant donné l'identifiant "3nkq2cxq2okb205z9ao6" (qui est la dernière entrée, # 62), comment puis-je mettre à jour cette collection mongo pour supprimer l'élément 62?

Je suis vraiment coincé. J'ai vu des questions de stackoverflow similaires, mais j'ai vraiment besoin de quelque chose de spécifique à ce problème.

Toute idée grandement appréciée.

Un grand merci à l'avance,

Si l'ID nous parlons est une MongoId (créée automatiquement), vous devez utiliser;

$collection->remove(array('id' => new MongoId('3nkq2cxq2okb205z9ao6')), true);

mais si le champ id est quelque chose que vous avez généré au hasard puis le code suivant est bon d'aller;

$collection->remove(array('id' => '3nkq2cxq2okb205z9ao6'));

Mmm. Cela n'a pas semblé fonctionner. Je pensais à quelque chose comme '$ collection-> update (array ('uname' => $ uname), array ('$ pull' => array ('posts' => array ('id' => $ id)))); ', mais cela ne fonctionne pas non plus ( – Eamorr

Ok, voici ce que je réussi à faire (mais pas idéal):

$idx=0; 
for($i=0;$i<sizeof($posts);$i++){ 
    $post=$posts[$i]; 
    if($post['id']==$id){ 
    $idx=$i; 
    break; 
    } 
} 
unset($posts[$idx]); 
$collection->update(array('uname'=>$uname),array('$set'=>array('posts'=>$posts)));
