random_api_migration¶Replaces rand, srand, getrandmax functions calls with their mt_*
analogs or random_int.
Risky when the configured functions are overridden. Or when relying on the seed based generating of the numbers.
replacements¶Mapping between replaced functions with the new ones.
Allowed types: array
Default value: ['getrandmax' => 'mt_getrandmax', 'rand' => 'mt_rand', 'srand' => 'mt_srand']
Default configuration.

The rule is part of the following rule sets:
Using the @PHP70Migration:risky rule set will enable the random_api_migration rule with the config below:
['replacements' => ['mt_rand' => 'random_int', 'rand' => 'random_int']]
Using the @PHP71Migration:risky rule set will enable the random_api_migration rule with the config below:
['replacements' => ['mt_rand' => 'random_int', 'rand' => 'random_int']]
Using the @PHP74Migration:risky rule set will enable the random_api_migration rule with the config below:
['replacements' => ['mt_rand' => 'random_int', 'rand' => 'random_int']]
Using the @PHP80Migration:risky rule set will enable the random_api_migration rule with the config below:
['replacements' => ['mt_rand' => 'random_int', 'rand' => 'random_int']]
