Using this rule is risky¶

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']

Example #1¶

Default configuration.

--- Original
+++ New
 <?php
-$a = getrandmax();
-$a = rand($b, $c);
-$a = srand();
+$a = mt_getrandmax();
+$a = mt_rand($b, $c);
+$a = mt_srand();

Example #2¶

With configuration: ['replacements' => ['getrandmax' => 'mt_getrandmax']].

--- Original
+++ New
 <?php
-$a = getrandmax();
+$a = mt_getrandmax();
 $a = rand($b, $c);
 $a = srand();

Example #3¶

With configuration: ['replacements' => ['rand' => 'random_int']].

--- Original
+++ New
-<?php $a = rand($b, $c);
+<?php $a = random_int($b, $c);
