Is there any way to get all values in one array without using foreach loops, in this example?
<?php
$foo = array(["type"=>"a"], ["type"=>"b"], ["type"=>"c"]);
The output I need is array("a", "b", "c")
I could accomplish it using something like this
$stack = [];
foreach($foo as $value){
$stack[] = $value["type"];
}
var_dump($stack);
But, I am looking for options that does not involve using foreach loops.
If you're using PHP 5.5+, you can use array_column(), like so:
$result = array_column($foo, 'type');
If you want an array with numeric indices, use:
$result = array_values(array_column($foo, 'type'));
If you're using a previous PHP version and can't upgrade at the moment, you can use the Userland implementation of array_column() function written by the same author.
Alternatively, you could also use array_map(). This is basically the same as a loop except that the looping is not explicitly shown.
$result = array_map(function($arr) {
return $arr['type'];
}, $foo);
array_values() isn't required here as array_column() will return desired array
each() or array_values() I guess its not possible. Thanks anywayEither use array_column() for PHP 5.5:
$foo = array(["type"=>"a"], ["type"=>"b"], ["type"=>"c"]);
$result = array_column($foo, 'type');
Or use array_map() for previous versions:
$result = array_map(function($x)
{
return $x['type'];
}, $foo);
Note: The loop will still be performed, but it will be hidden inside the aforementioned functions.
