php - How to merge array elements with comma separated value without using explode function

446

I want to merge array elements into comma separated values. This is an array

array:12 [
    0 => array:2 [
        "name" => "A1"
        "project" => array:1 [
            0 => "New Project"
        ]
    ]
    1 => array:2 [
        "name" => "A2"
        "project" => array:2 [
            0 => "New Project"
            2 => "Project"
        ]
    ]
]

My expected array should be like this

array:12 [
    0 => array:2 [
        "name" => "A1"
        "project" => array:1 [
            0 => "New Project"
        ]
    ]
    1 => array:2 [
        "name" => "A2"
        "project" => array:2 [
            0 => "New Project","Project"
        ]
    ]
]
