php - suma - Fusionar matrices asociativas múltiples a una única matriz de matrices asociativas

propiedades asociativa dela suma de matrices

Question

Tengo 4 matrices asociativas de la siguiente manera:

$ids  = array(
      ''0'' => ''7'' ,
      ''1'' => ''8'' ,
      ''2'' => ''9''
);
$names = array (
      ''0'' => ''Name 1'' ,
      ''1'' => ''Name 2'' ,
      ''2'' => ''another name''
);
$marks = array(
      ''0'' => ''8'' ,
      ''1'' => ''5'' ,
      ''2'' => ''8''
);
§grade = array(
      ''0'' => ''4'' ,
      ''1'' => ''2.5'' ,
      ''2'' => ''4''
);

Quiero "fusionarlos" en una sola matriz, que contiene matrices asociativas como se muestra a continuación:

$data = array(
   array(
      ''id'' => ''7'' ,
      ''name'' => ''Name 1'' ,
      ''marks'' => ''8'',
      ''grade'' => ''4''
   ),
   array(
      ''id'' => ''8'' ,
      ''name'' => ''Name 2'' ,
      ''marks'' => ''5'',
      ''grade'' => ''2.5''
   ),
   array(
      ''id'' => ''9'' ,
      ''name'' => ''another name'',
      ''marks'' => ''8'',
      ''grade'' => ''4''
   )
);

Soy un nuevo desarrollador de PHP y no tengo idea de cómo lograr esto. Su ayuda será muy apreciada. Gracias

Answer 1

Creo que esta es tu matriz

$ids = array(''0'' => ''7'',''1'' => ''8'',''2'' => ''9'');
$names = array(''0'' => ''Name 1'',''1'' => ''Name 2'',''2'' => ''another name'');
$marks = array(''0'' => ''8'',''1'' => ''5'',''2'' => ''8'');
$grade = array(''0'' => ''4'',''1'' => ''2.5'',''2'' => ''4'');

#New Keys
$keys = array("id","name","marks","grade");

A Puedes usar MultipleIterator

$final = array();
$mi = new MultipleIterator();
$mi->attachIterator(new ArrayIterator($ids));
$mi->attachIterator(new ArrayIterator($names));
$mi->attachIterator(new ArrayIterator($marks));
$mi->attachIterator(new ArrayIterator($grade));

foreach ( $mi as $value ) {
    $final[] = array_combine($keys, $value);
}
var_dump($final);

B. Puedes usar array_map

$final = array();
foreach ( array_map(null, $ids, $names, $marks, $grade) as $key => $value ) {
    $final[] = array_combine($keys, $value);
}
var_dump($final);

Salida

array
  0 => 
    array
      ''id'' => string ''7'' (length=1)
      ''name'' => string ''Name 1'' (length=6)
      ''marks'' => string ''8'' (length=1)
      ''grade'' => string ''4'' (length=1)
  1 => 
    array
      ''id'' => string ''8'' (length=1)
      ''name'' => string ''Name 2'' (length=6)
      ''marks'' => string ''5'' (length=1)
      ''grade'' => string ''2.5'' (length=3)
  2 => 
    array
      ''id'' => string ''9'' (length=1)
      ''name'' => string ''another name'' (length=12)
      ''marks'' => string ''8'' (length=1)
      ''grade'' => string ''4'' (length=1)
