php - push array into array - key issue

问题

i am trying to push multiple arrays into 1 big array, resulting in a 2 lvl array.

I got this set of arrays for example:

Array
(
    [cod] => ddd
    [denum] => ffffffffffffffff
    [descr] => ggggggg
    [cant] => 3
)
Array
(
    [cod] => fff
    [denum] => dfgdfgdfgdfgdfg
    [descr] => dfgdfgdfgdfgdfg
    [cant] => 33
)

But, after array push, i get this array:

Array
(
    [0] => Array
        (
            [0] => ddd
            [1] => ffffffffffffffff
            [2] => ggggggg
            [3] => 3
        )

    [1] => Array
        (
            [0] => fff
            [1] => dfgdfgdfgdfgdfg
            [2] => dfgdfgdfgdfgdfg
            [3] => 33
        )

)

Basically this is what i want to do, BUT, if you notice after the push, the keys are forgotten, and converted to numeric.

This is what i want it to look like:

Array
(
    [0] => Array
        (
            [cod] => ddd
            [denum] => ffffffffffffffff
            [descr] => ggggggg
            [cant] => 3
        )

    [1] => Array
        (
            [cod] => fff
            [denum] => dfgdfgdfgdfgdfg
            [descr] => dfgdfgdfgdfgdfg
            [cant] => 33
        )

)

sample code im using:

$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
   {
       array_push($res_arr_values, array_values($row));
   }

Can someone help me with it ?

回答1:

Don't use array_values on your $row

$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
   {
       array_push($res_arr_values, $row);
   }

Also, the preferred way to add a value to an array is writing $array[] = $value;, not using array_push

$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
   {
       $res_arr_values[] = $row;
   }

And a further optimization is not to call mysql_fetch_array($result, MYSQL_ASSOC) but to use mysql_fetch_assoc($result) directly.

$res_arr_values = array();
while ($row = mysql_fetch_assoc($result))
   {
       $res_arr_values[] = $row;
   }

回答2:

I think you have to go for

$arrayname[indexname] = $value;

回答3:

Use this..

$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
    $res_arr_values[] = $row;
}

回答4:

$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
    $res_arr_values[] = $row;
}


array_push == $res_arr_values[] = $row;

example 

<?php
$stack = array("orange", "banana");
array_push($stack, "apple", "raspberry");
print_r($stack);

Array
(
    [0] => orange
    [1] => banana
    [2] => apple
    [3] => raspberry
)
?>

回答5:

first convert your array too JSON

while($query->fetch()){
   $col[] = json_encode($row,JSON_UNESCAPED_UNICODE);
}

then vonvert back it to array

foreach($col as &$array){
   $array = json_decode($array,true);
}

good luck

All these answers are nice however when thinking about it....
Sometimes the most simple approach without sophistication will do the trick quicker and with no special functions.

We first set the arrays:

$arr1 = Array(
"cod" => ddd,
"denum" => ffffffffffffffff,
"descr" => ggggggg,
"cant" => 3
);
$arr2 = Array
(
"cod" => fff,
"denum" => dfgdfgdfgdfgdfg,
"descr" => dfgdfgdfgdfgdfg,
"cant" => 33
);

Then we add them to the new array :
