从数组foreach PHP获取变量值

Question

I'm using array foreach to get the value.

foreach($movie as $key=>$value) {
    if($key == 0) {
        echo $_SESSION['movie'] = $value;  //output1
    } else {
        echo $_SESSION['movie'] =  ", ".$value; 
    }   
}

echo $value; //output2

When it echo for output1:

movie1,movie2,movie3

When output 2:

movie3

I would like to use the variable $value outside of foreach but I can't get output1 result, and get only output2 result.

My desired output2:

movie1,movie2,movie3

Answer 1

If you're iterating the $movie array just to print the movies as a comma separated string, you don't need to.

echo implode(',', $movie);
