How to combine 3 or 4 arrays into one - php

Question

I have three following arrays.
Array ( [0] => 395 [1] => 295 )
Array ( [0] => 5a3a13f237715637629.jpeg [1] => 5a3b602654cfd527057.jpg )
Array ( [0] => Seller Test Product [1] => Offline Product for Test )
The first array is the quantity, the second array is for the images, the third array is for the name of the products.
I want to combine all these three array into one and display it using foreach loop in PHP.
if I use array_merge(), I am getting the output:
Array ( [0] => 395 [1] => 295 ) Array ( [0] => 5a3a13f237715637629.jpeg [1] => 5a3b602654cfd527057.jpg ) Array ( [0] => Seller Test Product [1] => Offline Product for Test ) Array ( [0] => 5a3a13f237715637629.jpeg [1] => 5a3b602654cfd527057.jpg [2] => Seller Test Product [3] => Offline Product for Test [4] => 395 [5] => 295 )
Now, how can I display it using foreach loop in the view.
in the view the code is :
<?php foreach($c as $key => $strs)
{ ?>
<img style="width:150px;" src="<?php echo #getimagesize(base_url("assets/upload/product/".$key)) ? base_url("assets/upload/product/".$key):'http://placehold.it/350x200';?>" class="img-responsive">
<input type="text" name="vala" value="<?php echo $strs; ?>">
<input type="text" name="valas" value="<?php echo $strss; ?>">
<?php } ?>
Any help is welcome.

Answer 1

So what you really want is to group all fields of all arrays together. Values with the same index shall be merged into a single object. array_map() can be used for this.
$final = array_map(function($quantity, $image, $name) {
return (object)['quantity' => $quantity, 'image' => $image, 'name' => $name];
}, $quantityArray, $imageArray, $nameArray);
The result will be:
[
{
'qunatity' => 395,
'image' => '5a3a13f237715637629.jpeg',
'name' => 'Seller Test Product'
},
{
'qunatity' => 295,
'image' => '5a3b602654cfd527057.jpeg',
'name' => 'Offline Product for Test'
}
]
You can then address them in your foreach like this:
foreach($final as $product) {
echo $product->name;
echo $product->image;
echo $product->quantity;
}
For those of you who are in a real hurry, the following call to array_map() will do the same trick, but without mapping the array fields to a specific key in the new multidimensional array:
$final = array_map(NULL, $quantityArray, $imageArray, $nameArray);
The result will be:
[
[
0 => 395,
1 => '5a3a13f237715637629.jpeg',
2 => 'Seller Test Product'
],
[
0 => 295,
1 => '5a3b602654cfd527057.jpeg',
2 => 'Offline Product for Test'
],
]
The inner arrays of the newly created mltidimensinal array will be filled in the order of which the arrays were provided to array_map().

Answer 2

You can loop one array and use key to get the corresponding value from the other arrays.
$a=array ( 0 => 395,1 => 295 );
$b=array ( 0 =>" 5a3a13f237715637629.jpeg" ,1 => "5a3b602654cfd527057.jpg" ) ;
$c=array ( 0 => "Seller Test Product",1 => "Offline Product for Test" );
Foreach($a as $key => $val){
$res[$key]['qty'] = $val;
$res[$key]['img'] = $b[$key];
$res[$key]['desc'] = $c[$key];
}
Var_dump($res);
Output:
array(2) {
[0]=>
array(3) {
["qty"]=> int(395)
["img"]=> string(25) " 5a3a13f237715637629.jpeg"
["desc"]=> string(19) "Seller Test Product"
}
[1]=>
array(3) {
["qty"]=> int(295)
["img"]=> string(23) "5a3b602654cfd527057.jpg"
["desc"]=> string(24) "Offline Product for Test"
}
}

Example Code
<?php
$array1=array ( 0 => 395,1 => 295 );
$array2=array ( 0 =>" 5a3a13f237715637629.jpeg" ,1 => "5a3b602654cfd527057.jpg" ) ;
$array3=array ( 0 => "Seller Test Product",1 => "Offline Product for Test" );
echo "<pre>";
print_r($array1);print_r($array2);print_r($array3);
$result=array_merge($array1,$array2,$array3);
print_r($result);
?>
