How do I add to the end of each sub array? Here is an example.
$products = array(
array( Code => 'TIR',
Description => 'Tires',
Price => 100
),
array( Code => 'OIL',
Description => 'Oil',
Price => 10
),
array( Code => 'SPK',
Description => 'Spark Plugs',
Price =>4
)
);
I want to add SKU=>1234 after Price in each array. Thanks
Loop across the array and use references to modify it:
foreach ($products as &$v) {
$v['SKU'] = 1234;
}
unset($v)), or you'll end up with some very confusing behavior -- you'll end up overwriting $products[2], in this example. To protect against this, I'm in the habit of immediately unset()ting the reference immediately after the completion of the loop... just in case any code below ever decides it wants to use the same variable name.foreach ($products as $k=>$v){
$v['SKU']=1234;
$products[$k]=$v;
}
print_r($products);
$products[$k]['SKU']=1234;foreach ( $products as &$arr )
$arr['SKU'] = 1234;
Loop over the array using a reference (Note the ampersand before the $val):
foreach ( $products as &$val ){
$val['SKU'] = 1234;
}
That way rather than $val being a copy of the array element, it is a reference to the value, so altering it alters the value held in $products.
For completeness, functional iteration can be used to append the new element to all rows to create a new array.
Code: (Demo)
$new = ['SKU' => 1234];
var_export(
array_map(fn($row) => $row + $new, $products)
);
Or use functional iteration to modify by reference instead of returning the data. Demo
$new = ['SKU' => 1234];
array_walk($products, fn(&$row) => $row += $new);
var_export($products);
