print.nonString

Code example

<?php declare(strict_types = 1);

$values = [1, 2, 3];
print $values;

Why is it reported?

The argument passed to print cannot be converted to a string. In the example above, $values is an array, which does not have a __toString() method and cannot be implicitly converted to a string.

How to fix it

Convert the value to a string before printing:

 <?php declare(strict_types = 1);

 $values = [1, 2, 3];
-print $values;
+print implode(', ', $values);
