How to convert an array to a string in PHP?
Use the implode() function to join the values of an array into a string. If you need the complete array with keys, use json_encode().
<?php
$numbers = [1, 2, 5, 12];
echo implode(",", $numbers);
?>Output:
Tutorials Class - Output Window
1,2,5,12
<?php
$user = ["name" => "Robin", "age" => 25];
echo json_encode($user);
?>Output:
Tutorials Class - Output Window
{“name”:”Robin”,”age”:25}
Note:
If you try echo $array directly, PHP prints the word “Array” and gives a warning “Array to string conversion”. Use one of the functions above instead.
