转换或重新排列PHP阵列

Question

我想转换或重新排列此php数组：

$contacts = array(
array(
    "name" => "Peter Parker",
    "email" => "[e-mail]",
),
array(
    "name" => "Peter Parker", 
    "email" => "[e-mail]",
),
array(
    "name" => "Harry Potter",
    "email" => "[e-mail]",
)
);

to：

 $contacts ["Peter Parker"] = {"[e-mail]", "[e-mail]"  } ;
 $contacts ["Harry Potter"] = {"[e-mail]"} ;

这意味着在新数组或行中使用相同名称组装或合并条目。

Answer 1

foreach( $contacts as $record ){
    $newcontacts[$record['name']][] = $record['email'];
}

Answer 2

类似的东西应该有效：

foreach ($contacts as $name => $email){
    $merged[$name][] = $email;
}
