How to get array element by passing another array element ?

Question

I have an array follow

[0] => Array
 (
    [month] => Oct
    [amount] => 1200.00
 )

and how do i get [amount] by passing [month]

Answer 1

You don't. Two options:

1. Loop:

    foreach ($array as $i) { if ($i['month'] == 'Oct') { echo $i['amount']; } } 

2. Index the data by month:

    $array = array_combine(array_map(function($i) { return $i['month']; }, $array), $array); echo $array['Oct']['amount']; 

Answer 2

foreach ($arr as $k => $v) {
    if ($v['month'] == $needleMonth) {
        echo $v['amount'] . ' - that`s it';
        break;
    }
}

Answer 3

您必须循环数组并每次测试是否需要的月份== $ arrayElement [$ i] ['month']

Answer 4

foreach ($arr as $k=>$v) {
    if ($v['month']=='Oct') {
        echo $v['amount'];
    }
}

Answer 5

$selectedMonth = 'Oct';

foreach($yourArray as $child){

    if($child['month'] == $selectedMonth){
        echo $child['amount'];
    }

}
