My Array shown as follows:
Array
(
[0] => Array
(
[amount_id] => 1
[enquiry_id] => 1
[project_id] => 1
)
[1] => Array
(
[amount_id] => 4
[enquiry_id] => 4
[project_id] => 4
)
[2] => Array
(
[amount_id] => 5
[enquiry_id] => 5
[project_id] => 5
)
)
This Array can be increase. How can i get value of each 'amount_id' from this array? What function should i use? Can for each function will work?
Just try with:
$input = array( /* your data */ );
$output = array();
foreach ($input as $data) {
$output[] = $data['amount_id'];
}
You can use a one-liner array_walk() to print those..
array_walk($arr,function($v){ echo $v['amount_id']."<br>";});
Do like this in array_map or Use array_column for The version PHP 5.5 or greater
$outputarr= array_map(function($item){ return $item['amount_id'];},$yourarr);
print_r($outputarr);
Try the following, this is accessing the specific array - easier to debug later on and better speed:
$num=count($your_array);
for($i="0"; $i<$num; $i++)
{
echo $your_array[$i]['amount_id'];
}
you could loop until $i < count($your_array) but it means that the count will run in every loop, for high performance sites I wouldn't do it.
you could access a specific element in a 2D array by $your_array[$the_index]['amount_id'] or other index.
