How to access the array elements?

Answer 1

Let's assume your array is $arr, you can do
echo $arr[0]['num'];
echo $arr[0]['yyyy'];
echo $arr[0]['mm'];
echo $arr[0]['dd'];
As you are fetching from a database, you will receive an array for each result row, and within each array will be another array of columns. you can use a foreach() loop to iterate over the data, as follows:
foreach($arr as $row) {
echo $row['num'] . ':' . $row['yyyy'] . '-' . $row['mm'] . '-' . $row['dd'] . "\n";
}

Answer 2

try this
foreach($array as $value) {
foreach($value as $k=>$v) {
echo $k . " : " . $v .'<br/>';
}
echo '<hr>';
}

Answer 3

Please have a look at the official PHP Doc article about arrays.
In your case:
$yourArrayVariable[0]['yyyy']
Will let you access the element with value 2013.
Or if you have an undefined number of array entries you can iterate over it with either foreach or for.
foreach($yourArrayVariable as $key => $value) {
echo $key , ': ' , $value , '<br>';
}
or if you have only numeric indeces without a gap:
$arrCount = count($yourArrayVariable);
for($i = 0; $i < $arrCount; ++$i) {
echo $i , ': ' , $arrCount[0] , '<br>';
}

Answer 4

store array in a variable like
$arr =array(1) {
[0]=>
array(4) {
["num"]=>
string(1) "1"
["yyyy"]=>
string(4) "2013"
["mm"]=>
string(2) "12"
["dd"]=>
string(2) "11"
}
}
for access array elements you have to use following code
echo $arr[0]['num'];
echo $arr[0]['yyyy'];
echo $arr[0]['mm'];
echo $arr[0]['dd'];o $arr[0]['num']

Answer 5

$arr =Array(
0=>array(
"num"=>"1",
"yyyy"=>"2013",
"mm"=>"12",
"dd"=>"11",
)
);
foreach ($arr as $value) {
echo "num: ".$value["num"];
echo "yyyy: ".$value["yyyy"];
echo "mm: ".$value["mm"];
echo "dd: ".$value["dd"];
}

Answer 6

You can get the value using echo $array[0]['num']; gives output as 1
$array ='your array data here';
foreach($array as $key=>$value) {
echo "num: ". $value['num'] . "/yyyy: ". $value['yyyy']. " /mm: ". $value['mm'] . " /dd: ". $value['dd'] . "<br>";
}
