eregi_replace depricated how to replace correctly?

Question

I just discovered that the eregi is deprecated, and that preg replace works differently. How would you translate this?

$text = eregi_replace("\\[img\\]([^\\[]*)\\[/img\\]", "", $text);

Answer 1

Apparently this works:

$text = preg_replace("#\[img\](.+?)\[/img\]#is", "", $text);

Answer 2

you can try this one

$text = preg_replace("/\\[img\\]([^\\[]*)\\[/img\\]/i", "", $text);

1. encode your pattern between / and /i
2. use preg_replace instead of eregi_replace
