Remove everything before the dash from a Laravel array-CodePudding

I have a Laravel array and would like to modify the returned values.

$array = ['hr-34', 've-53', 'dv-65'];

I want to remove everything before the dash and the dash itself and return the following array.

$array = ['34', '53', '65'];

You can do something like this:

foreach ($c as $key => $value) {
    $pieces = explode('-', $value);
    $array[$key] = $pieces[1];
}

You have used the tag collections. So if it's a collection you can use this function:

$c->map(function ($item) {
    return explode('-', $item)[1];
})

Steps to follow:

define blank array $new_array (to fill single value from foreach loop).
get single value using foreach loop.
use strstr for remove everything before dash and remove '-' using str_replace.
fill single value in $new_array.
return $new_array outside foreach loop.

Below is the code -

$array = ['hr-34', 've-53', 'dv-65'];

$new_array = array();
foreach($array as $key=>$result){
    $data = str_replace('-', '', strstr($result, '-'));
    $new_array[]= $data;
}

print_r($new_array);

That's all!

$array = array_map(function ($item) {
    return explode('-', $item)[1];
}, $array)

Edit: As you changed title from array to collection you can use: https://laravel.com/docs/9.x/collections#method-map

$collection->map(...)

in a similar way to array_map(...)

CodePudding user response：

$array = ['hr-34', 've-53', 'dv-65'];

$array = collect($array)
    ->map(fn($item) => explode('-', $item)[1])
    ->all();

/**
 * array:3 [
 *     0 => "34"
 *     1 => "53"
 *     2 => "65"
 * ]
 */
dd($array);

you can use regex with preg_replace as :

$new = array_map(function ($item) {
        return preg_replace('/^([^-]) -/', '', $item);
    }, $array);

result :

array:3 [
 0 => "34"
 1 => "53"
 2 => "65"
]
