PHP: Filtering multidimensional arrays - php

Question

I'm trying to filter the following multidimentional array:
Array (
[0] => stdClass Object ( [term_id] => 5 [name] => Freelance [slug] => freelance-category1 [term_group] => 0 [term_taxonomy_id] => 5 [taxonomy] => job_listing_type [description] => [parent] => 0 [count] => 0 )
[1] => stdClass Object ( [term_id] => 2 [name] => Full Time [slug] => full-time-category2 [term_group] => 0 [term_taxonomy_id] => 2 [taxonomy] => job_listing_type [description] => [parent] => 0 [count] => 0 )
[2] => stdClass Object ( [term_id] => 6 [name] => Internship [slug] => internship-category1 [term_group] => 0 [term_taxonomy_id] => 6 [taxonomy] => job_listing_type [description] => [parent] => 0 [count] => 0 )
[3] => stdClass Object ( [term_id] => 3 [name] => Parta Time [slug] => part-time-category2 [term_group] => 0 [term_taxonomy_id] => 3 [taxonomy] => job_listing_type [description] => [parent] => 0 [count] => 0 )
[4] => stdClass Object ( [term_id] => 4 [name] => Temporary [slug] => temporary-category1 [term_group] => 0 [term_taxonomy_id] => 4 [taxonomy] => job_listing_type [description] => [parent] => 0 [count] => 0 ) )
I want to filter each item where [slug] => something-category1 into a different array and [slug] => something-category2 into a different array. The criteria for filtering is the ending part after the hip-fun.
Any help would be appreciated.

There is nothing fancy to advise here. Just iterate the array of objects, isolate the target substring in the slug value, then route any qualifying objects to their respective new group.
Code: (Demo)
$cat1 = [];
$cat2 = [];
foreach ($objects as $object) {
if ($dash = strrpos($object->slug, '-')) { // don't need to check for false-vs-0 due to task logic
$cat = substr($object->slug, ++$dash); // or $dash + 1 ...same thing
if ($cat == 'category1') {
$cat1[] = $object;
} elseif ($cat == 'category2') {
$cat2[] = $object;
}
}
}
echo "Category1 : ";
var_export($cat1);
echo "\n---\n";
echo "Category2 : ";
var_export($cat2);
Output:
Category1 : array (
0 =>
(object) array(
'term_id' => 5,
'name' => 'Freelance',
'slug' => 'freelance-category1',
'term_group' => 0,
'term_taxonomy_id' => 5,
'taxonomy' => 'job_listing_type',
'description' => NULL,
'parent' => 0,
'count' => 0,
),
1 =>
(object) array(
'term_id' => 6,
'name' => 'Internship',
'slug' => 'internship-category1',
'term_group' => 0,
'term_taxonomy_id' => 6,
'taxonomy' => 'job_listing_type',
'description' => NULL,
'parent' => 0,
'count' => 0,
),
2 =>
(object) array(
'term_id' => 4,
'name' => 'Temporary',
'slug' => 'temporary-category1',
'term_group' => 0,
'term_taxonomy_id' => 4,
'taxonomy' => 'job_listing_type',
'description' => NULL,
'parent' => 0,
'count' => 0,
),
)
