Convert array to string in PHP 7

in this post, We’ll convert the array elements into a string. We are going to convert the array to string using three methods.

Array to String in PHP

Let’s convert array elements to string using PHP 7. We’ll discuss implode(), json_encode() and join() method and create sample example to convert array to string.

Convert Array to String Using implode()

The implode() method is a PHP built-in function for joining the items of an array. We just need to pass two parameters, One is an array of strings and the second is a delimiter (string to be used between the pieces) of your response string.

The delimiter is used to join them together into one string.

Syntax:

implode (separator, array)

Let’s take a simple example –

$blog_arr = Array ("Hi,","I","am","phpflow","blog.");
$str = implode(" ",$blog_arr);
echo $str;

Output:
Hi, I am phpflow blog.

PHP Array to String Using json_encode()

The json_encode() function is a PHP inbuilt function that converts a PHP array or object to a JSON representation.

Syntax:

string json_encode( $value, $option, $depth )

The sample example:

$blog_arr = Array ("Hi,","I","am","phpflow","blog.");
$str = json_encode($blog_arr);
echo $str;

Output:
Hi, I am phpflow blog.

Array to String Using join()

The join() method is a PHP built-in function that connects an array of elements separated by a string.

Syntax:

string join( $separator, $array)

The sample example:

$blog_arr = Array ("Hi,","I","am","phpflow","blog.");
$str = join(" ", $blog_arr);
echo $str;

Output:
Hi, I am phpflow blog.
