将数组从索引转换为简单字符串

I have an indexed array but I need to convert it in simple array just like below. hope you can help me.

This is my current array

Array
(
[0] => 4
[1] => 4
[2] => 0
[3] => 3
[4] => 3

)

But I need to convert it into like this.

array("4","4","0","3","4");

or much better if unique like this

array("4","4","0","3","4");

Thank you

I'm not sure to understand your request, I propose you to test this:

$array = [
    "0" => "4",
    "1" => "4",
    "2" => "0"
];

$string = "";

foreach ($array as $key => $value) {
    $string = $string.$value;
}

It returns "440".

Hope it can help you

try this one:

        $a = array("4", "4", "0", "3", "4");
        $str = 'array(';
        foreach ($a as $key => $value) {
            $str.='"' . $value . '",';
        }
        $str = trim($str, ',');
        $str.=')';
        echo $str;

Outpur: array("4","4","0","3","4")
