This time I will bring you PHP usageforeachconversionarraydetailed steps, what are the precautions for using foreach in PHP to convert arrays, the following is a practical case , let’s take a look.
Requirements:
Convert two-dimensional array$arr to 'time' and 'type' Standard, 'data' is a two-dimensional array of values;
Original array:
$arr = array( 0 => array( 'data' => 100, 'type' => 1, 'time' => '2018-01-26', ), 1 => array( 'data' => 200, 'type' => 2, 'time' => '2018-01-26', ), 2 => array( 'data' => 300, 'type' => 2, 'time' => '2018-01-27', ), 3 => array( 'data' => 400, 'type' => 3, 'time' => '2018-01-27', ), 4 => array( 'data' => 500, 'type' => 4, 'time' => '2018-01-28', ), );
Conversion:
foreach ($arr as $key => $value) {
$change[$value['time']][$value['type']] = $value['data'];
}Result:
array(3) {
["2018-01-26"] => array(2) {
[1] => int(100)
[2] => int(200)
}
["2018-01-27"] => array(2) {
[2] => int(300)
[3] => int(400)
}
["2018-01-28"] => array(1) {
[4] => int(500)
}
