How to create variables using a php array? - php

Question

I have a PHP array, something like below:
Array(
[0] => Array
(
[name] => month_year
[value] => 201609
)
[1] => Array
(
[name] => advance_amount
[value] => 50%
)
)
Using this array, I want to create 2 variables like this:
$month_year = '201609';
$advance_amount = '50%';
Can anybody tell me is this possible in php?
I tried it using two foreach but I don't have any idea how to precced.
foreach ($_POST as $k => $data) {
//echo "<pre>", print_r($data)."</pre>";
foreach ($data as $key => $value) {
echo $key."<br>";
}
}

Answer 1

Use variable variables. Your foreach loop should be like this:
foreach ($_POST as $k => $data) {
$$data['name'] = $data['value'];
}
// display variables
echo $month_year . "<br />";
echo $advance_amount;

Answer 2

PHP7 style:
$a = [['name' = 'month_year', 'value' => '201609'], ['name' => 'advance_amount', 'value' => '50%']];
foreach ($a as $line) {
${$line['name']} = $line['value'];
}
php > echo $month_year; //201609
Have a look at the Variables reference
Caution
Further dereferencing a variable property that is an array has
different semantics between PHP 5 and PHP 7. The PHP 7.0 migration
guide includes further details on the types of expressions that have
changed, and how to place curly braces to avoid ambiguity.

Answer 3

using list it gives you the cleaner way to solve the issue: for example
$data = [
[
'name' => 'month_year',
'value' => 201609
],
[
'name' => 'advance_amount',
'value' => '50%'
]
];
list($month_year, $advance_amount) = array_map(function($value){
return $value['value'];
}, $data);
echo sprintf('Month of the year is %s with porcentage %s', $month_year, $advance_amount);
This will have the result you are looking for with a clearer code.
Month of the year is 201609 with porcentage 50%

Answer 4

first create loop and declare var.
$data = array(array(
'name' => 'month_year',
'value' => 201609,
), array(
'name' => 'advance_amount',
'value' => '50%',
)
);
foreach ($data as $key => $value) {
${$value['name']} = $value['value'];
}
echo $month_year;
echo '<br>';
echo $advance_amount;
