Dynamic usage of preg_replace

[wordish]

Dynamic usage of preg_replace is not ideal.
Please check manually for /e modifier or user input

File	Line	Col
/controller.php	115	16
/controller.php	162	16
/controller.php	216	16
/controller.php	275	29
/controller.php	283	33
/controller.php	287	33
/controller.php	295	37

I know what you're suggesting, but there are some complex regex that were (disclaimer/accredited in function comments); thus, making it hard to convert. I also read that preg_replace /e modifier has been deprecated since php 5.5

If it's just simply preg_replace_callback conversion or empty string check, please add pull request?
