Group: Language level migration · PhpStorm name: GetDebugTypeCanBeUsedInspection

The hand-rolled idiom "class name for objects, gettype() otherwise", written as a ternary over is_object(), is what PHP 8.0's get_debug_type() provides in one call. Suggest the built-in.

Example

Language level 8.1:

<?php
namespace Shop;

function label(object|string $payload, array $rows): array {
    return [
        is_object($rows[0]) ? get_class($rows[0]) : gettype($rows[0]),
        'kind: ' . (\is_object($payload) ? \get_class($payload) : gettype($payload)),
        is_object($payload) ? get_class($payload) : gettype($rows),
        is_object($payload) ? gettype($payload) : get_class($payload),
        is_object($payload) ? get_class($payload) : 'scalar',
        is_object($payload) ?: gettype($payload),
        (is_object($payload)) ? get_class($payload) : gettype($payload),
    ];
}

Reported:

• line 6: Use 'get_debug_type($rows[0])' instead (scalar type names differ from gettype()).
• line 7: Use '\get_debug_type($payload)' instead (scalar type names differ from gettype()).

Configure

In custos.json:

{
  "rules": {
    "GetDebugTypeCanBeUsed": {
      "enabled": false
    }
  }
}

Suppress

Before the statement or declaration (or the first statement of the file), either of:

// @custos-ignore GetDebugTypeCanBeUsed

/**
 * @noinspection GetDebugTypeCanBeUsedInspection
 */
