将数组转换为一个长字符串[关闭]

If I have an array in php that contains a simple list e.g:

$colors = $array();
$colors = 'black', 'white', 'blue', 'red';

Is there a function or a way to loop through the array to make a variable equal a STRING of the results?
For example:

$theseColors = 'black, white, blue, red';

Cheers!

$theseColors  = implode(', ',$colors);

Try this,

http://php.net/manual/en/function.implode.php.

Join / implode...

$theseColors = implode(', ', $colors);

$colors = $array(); $colors = 'black', 'white', 'blue', 'red';

won't work. it's an error here. this is correct:

$colors = array(); $colors = array('black', 'white', 'blue', 'red');

and then

$theseColours  = implode(", ", $colors);

foreach ($color as $colors) {
    $theseColours = $theseColours . $color;
}
