+The `str_repeat()` function returns a string that repeats a substring a specified number of times.
+
+## Syntax
+
+```pseudo
+str_replace($string, $repeat)
+```
+
+- `$string`: Specifies the string to repeat and it is required.
+- `$repeat`: Specifies the number of times the string will be repeated. Must be greater or equal to 0 and it is also required.
+
+## Codebyte Example
+
+This example provides a few demonstrations of `str_repeat()` operating on a string.
+
+> **Note:** The third echo statement will not output to the console due to the second argument of `str_repeat` being set to `0`.
+
+```codebyte/php
+<?php
+
+echo (str_repeat("I-am-repeated ",3)."\n");
+echo (str_repeat("Cool ",10). "\n");
+echo (str_repeat("I-don't-appear ",0). "\n");
+
+?>
+```
