Insert a element from php variable in associative array

I have a conditional string like this:

echo $cnd = "'use_funds'=>'no'";

And my $data array is :

$data = array(
    $cnd,
    'quantity'   => $_POST['qty_' . $q],
    'veg_name'   => $_POST['veg_name_' . $q],
    'rate'       => $_POST['rate_' . $q],
    'ws_price'   => $_POST['ws_price_' . $q],
    'ret_price'  => $_POST['ret_price_' . $q],
    'mop'        => $_POST['mop_' . $q],
    'ret_margin' => $_POST['ret_margin_' . $q]
);

The above echo $cnd shows 'use_funds'=>'no', but the var_dump($data) shows array 0 => string ''use_funds'=>'no'' (length=17) . And since its a string my data is not inserting in my table. How can I make the $cnd to a associative array element instead of string?

If it must be a string, split it and add it to the array. http://php.net/manual/en/function.explode.php

The explode function takes a string and breaks it into an array

$my_string_split = explode('=>', $cnd);
// returns [0 => 'use_funds', 1 => 'no']
$data[$my_string_split[0]] = $my_string_split[1];

If it does not need to be a string, do it literally:

$data['use_funds'] = 'no';

echo $cnd = "'use_funds'=>'no'";

The above line considers "'use_funds'=>'no'" as a string and assigns it to $cnd. So no matter what, it always remains as a string unless you make any proper change to it. The default key in that case will be 0. So, it will be like:

[0] => "'use_funds'=>'no'"

To get around this problem, you can do this:

$cnd = array('use_funds'=>'no');

Then, you an use array_merge() function to merge the two like this:

array_merge($cnd, $data);

first of all your $cnd is string , not an array. and you are trying to append this $cnd with $data array.

for adding element to an array we basically use push() method. For your case if you use array_push method then you will get a output like below

array_push($cnd,$data);
$data=array(
                                    0=>'use_funds'=>'no',
                                    'quantity'=>$_POST['qty_'.$q],
                                    'veg_name'=>$_POST['veg_name_'.$q],
                                    'rate'=>$_POST['rate_'.$q],
                                    'ws_price' => $_POST['ws_price_'.$q],
                                    'ret_price' => $_POST['ret_price_'.$q],
                                    'mop' => $_POST['mop_'.$q],
                                    'ret_margin' =>$_POST['ret_margin_'.$q]
  );

so my suggession will be if you want you desire result then follow below step:-

 either define your $cnd as an array and then use array_merge();

You can accomplish it using eval

$cnd = "'use_funds'=>'no'";

eval("\$x = array($cnd);");

print_r($x);

don't use the $cnd part to make and insert the data in the array:

Use the below code:

$data['use_funds'] = 'no';

And this code will append the array. OR you can use the array_push function of PHP.
