Create an array from 2 other arrays

As quoted in the comments, you can make one condition, see this is an example, you can have others.

$Fornecedores = [
  [ 'ID_For' => 1, 'ID_Pes' => 1, 'STATUS' => 1 ],
  [ 'ID_For' => 2, 'ID_Pes' => 2, 'STATUS' => 2 ],
  [ 'ID_For' => 3, 'ID_Pes' => 3, 'STATUS' => 3 ],
];
$Pessoas = [
  [
    'ID_Pes' => 1,
    'NOME' => 'Pessoa 1',
    'FANTASIA' => 'Fantasia 1',
    'CPF/CNPJ' => '111.111.111-11'
  ],
  [
    'ID_Pes' => 2,
    'NOME' => 'Pessoa 2',
    'FANTASIA' => 'Fantasia 2',
    'CPF/CNPJ' => '222.222.222-22'
  ],
  [
    'ID_Pes' => 3,
    'NOME' => 'Pessoa 3',
    'FANTASIA' => 'Fantasia 3',
    'CPF/CNPJ' => '333.333.333-33'
  ],
];

$For_Pessoa = [];

for ($i = 0; $i < count($Fornecedores); $i++) {
  // Verifica se ID_Pes de ambos são iguais
  if ($Fornecedores[$i]['ID_Pes'] == $Pessoas[$i]['ID_Pes']) {
    // Combina os dois resultados e gurda na variável.
    $ForPessoa = array_merge($Fornecedores[$i], $Pessoas[$i]);
    // Adiciona na nova Array
    array_push($For_Pessoa, $ForPessoa);
  }
}

print_r($For_Pessoa);

The output will be:

Array
(
    [0] => Array
        (
            [ID_For] => 1
            [ID_Pes] => 1
            [STATUS] => 1
            [NOME] => Pessoa 1
            [FANTASIA] => Fantasia 1
            [CPF/CNPJ] => 111.111.111-11
        )

    [1] => Array
        (
            [ID_For] => 2
            [ID_Pes] => 2
            [STATUS] => 2
            [NOME] => Pessoa 2
            [FANTASIA] => Fantasia 2
            [CPF/CNPJ] => 222.222.222-22
        )

    [2] => Array
        (
            [ID_For] => 3
            [ID_Pes] => 3
            [STATUS] => 3
            [NOME] => Pessoa 3
            [FANTASIA] => Fantasia 3
            [CPF/CNPJ] => 333.333.333-33
        )

)

  

You can see it working here at repl.it

Let's simulate your solution as the example you passed, I believe that there is a more optimized way is just one of the implementation possibilities.

Copying and pasting you will be able to run the above code and see if I came close to your question.

First I want to apologize for the delayed return, short weeks and long holidays:)).

Second to thank everyone for the help they provided, they were of great value to my conclusion and solution. So I did not choose one, but I scored all of them. (I do not know if I did it right.)

Third Solution:

1 - I have loaded all the active providers (STATUS) into an array, since this is technically smaller in terms of registers (Base).

$Fors= array();
$Foreg = array();

if ( $Fors_db = "Usei Classe para fazer o Select e retornar a informação" )
{
   foreach( $Fors_db as $For )
   {
       $Fors[] = $For->FOR_PESSOAID;

       $Foreg[ $For->FOR_PESSOAID ] = $For;
   } 
} 
else $Fors[] = '0';

2 - I loaded all the People, which has a link with the Suppliers $ Fors [], that is, I used an (IN) in the select. In a foreach I loaded a datagrid by adding the Vendor information.

if ( $objects = "Usei Classe para fazer o Select e retornar a informação" )
{
    foreach ( $objects as $object )
    {
        $object->FOR_ID      = $Foreg[ $object->PES_ID ]->FOR_ID;
        $object->PES_TIPO    = $TpPess[ $object->PES_TIPO ];
        $object->PES_CPFCNPJ = TGeral::CpfCnpj( $object->PES_CPFCNPJ );
        $object->PES_CEP     = TGeral::Cep( $object->PES_CEP );
        $object->PES_STATUS  = $Foreg[ $object->PES_ID ]->FOR_STATUS;
        $object->PES_ULTIMA  = TDate::date2br( $object->PES_ULTIMA );

        datagrid->addItem( $object );
    }
}
