How to convert an array to a string in PHP?

Question

For an array like the one below; what would be the best way to get the array values and store them as a comma-separated string?

Array ( [0] => 33160,
                 


        

Answer 1

Using implode(), you can turn the array into a string.

$str = implode(',', $array); // 33160,33280,33180,...

Answer 2

I would turn it into a json object, with the added benefit of keeping the keys if you are using an associative array:

 $stringRepresentation= json_encode($arr);

Answer 3

PHP's implode function can be used to convert an array into a string --- it is similar to join in other languages.

You can use it like so:

$string_product = implode(',', $array);

With an array like [1, 2, 3], this would result in a string like "1,2,3".

Answer 4

implode?

Answer 5

I would turn it into CSV form, like so:

$string_version = implode(',', $original_array)

You can turn it back by doing:

$destination_array = explode(',', $string_version)

Answer 6

serialize() and unserialize() convert between php objects and a string representation.
