Array foreach or use for loop - php

Question

I have array ...
Array
(
[0] => Array
(
[id] => 1
[number1] => 0
[value] => 3
)
[1] => Array
(
[id] => 2
[number1] => 0
[value] => 3
)
[2] => Array
(
[id] => 3
[number1] => 0
[value] => 11
)
[3] => Array
(
[id] => 4
[number1] => 1
[value] => 10
)
[4] => Array
(
[id] => 5
[number1] => 1
[value] => 13
)
current my code ...
$namearray=array();
foreach($myArray as $key => $value){
if($value['number1']==0){
$namearray[0][]=$value['value'];
}
if($value['number1']==1){
$namearray[1][]=$value['value'];
}
}
print_r($namearray);
my code current output:
Array
(
[0] => Array
(
[0] => 3
[1] => 3
[2] => 11
)
[1] => Array
(
[0] => 10
[1] => 13
)
)
How to use loop to replace if $value['number1']==0 and $value['number1']==1 ?
I maybe have more number1 number!
I try to use for loop but not work ! It will not display anything.

You could use the number1 value to select the index.
$namearray = [];
foreach ($myArray as $key => $value) {
$index = $value['number1']; // get the index
$namearray[$index][] = $value['value']; // use it
}
print_r($namearray);
ex:
$myArray = [
['id' => 1, 'number1' => 0, 'value' => 3],
['id' => 2, 'number1' => 0, 'value' => 3],
['id' => 3, 'number1' => 0, 'value' => 11],
['id' => 4, 'number1' => 1, 'value' => 10],
['id' => 5, 'number1' => 1, 'value' => 13],
];
$namearray = [];
foreach ($myArray as $key => $value) {
$index = $value['number1'];
$namearray[$index][] = $value['value'];
}
print_r($namearray);
Output :
Array
(
[0] => Array
(
[0] => 3
[1] => 3
[2] => 11
)
[1] => Array
(
[0] => 10
[1] => 13
)
)
