我希望每个['added_on']获得'08 -11-11'的价值是否可能？

I want to get specific value from $each['added_on']. Is it possible?

This is the code I am using.

$array = array();
$array[] = array('note' => 'asdf', 'added_on' => '15-11-11');
$array[] = array('note' => 'abcd', 'added_on' => '15-11-11');
$array[] = array('note' => 'qwer', 'added_on' => '15-11-11');
$array[] = array('note' => 'zxcv', 'added_on' => '08-11-11');

foreach ($array as $each) {
   print_r($each['added_on']);
}

foreach ($each['added_on'] as $value) {
    print_r($value[0]);
}

I guess the easiest way is with a classic IF:

$array = array();
$array[] = array('note' => 'a', 'added_on' => '15-11-11');
$array[] = array('note' => 'b', 'added_on' => '15-11-11');
$array[] = array('note' => 'c', 'added_on' => '15-11-11');
$array[] = array('note' => 'd', 'added_on' => '08-11-11');

foreach ($array as $entry) {
    if ($entry['added_on'] == '08-11-11') {
        echo "its a match";
    }
}

You can do this without any IF or FOREACH, but you can never be sure you get the correct result. Use this only if the array never changes:

var_dump($array[3]['added_on']);

You can use array_search and array_column

check working demo here: https://eval.in/868516

$array = array();

$array[] = array('note' => 'test', 'added_on' =>'15-11-11');
$array[] = array('note' => 'test', 'added_on' =>'15-11-11');
$array[] = array('note' => 'test', 'added_on' =>'15-11-11');
$array[] = array('note' => 'test', 'added_on' =>'08-11-11');

echo('<pre>');
print_r($array);

$key = array_search('08-11-11', array_column($array, 'added_on')); // get key of value

echo $array[$key]['added_on']; // assuming positive result

try:

<?php
  $array = array();
  $array[] = array('note' => 'a', 'added_on' => '15-11-11');
  $array[] = array('note' => 'b', 'added_on' => '15-11-11');
  $array[] = array('note' => 'c', 'added_on' => '15-11-11');
  $array[] = array('note' => 'd', 'added_on' => '08-11-11');

  foreach ($array as $entry) {
    if($entry['added_on'] == '08-11-11'){
        echo $entry['added_on'];
     }
  }
?>
