[SOLVED] eregi to preg

[baxr6]

Im converting my regex for php 5.3 and I am stuck on the following

 

if((eregi("<[^>]script*\"?[^>]*>", $secvalue)) ||
	  (eregi("<[^>]*object*\"?[^>]*>", $secvalue)) ||
	  (eregi("<[^>]*iframe*\"?[^>]*>", $secvalue)) ||
	  (eregi("<[^>]*applet*\"?[^>]*>", $secvalue)) ||
	  (eregi("<[^>]*meta*\"?[^>]*>", $secvalue)) ||
	  (eregi("<[^>]style*\"?[^>]*>", $secvalue)) ||
	  (eregi("<[^>]*form*\"?[^>]*>", $secvalue)) ||
	  (eregi("<[^>]*img*\"?[^>]*>", $secvalue)) ||
	  (eregi("<[^>]*onmouseover*\"?[^>]*>", $secvalue)) ||
	  (eregi("<[^>]body*\"?[^>]*>", $secvalue) && !eregi("<[^>]tbody*\"?[^>]*>", $secvalue)) ||
	  (eregi("\([^>]*\"?[^)]*\)", $secvalue)) ||
	  (eregi("\"", $secvalue)) ||
	  (eregi("forum_admin", $sec_key)) ||
	  (eregi("inside_mod", $sec_key))) {
		  block_ip($blocker_row);
	  }

 

anyone got any ideas on how to convert this to preg.so far I have this

 

$html_regex = '{
^(
(?: <script\b[^>]*>.*?</script> # script block
| <object\b[^>]*>.*?</object> # object block
| <iframe\b[^>]*>.*?</iframe> # iframe block
| <applet\b[^>]*>.*?</applet> # applet block
| <meta\b[^>]*>.*?</meta> # meta block
| <style\b[^>]*>.*?</style> # style block
| <form\b[^>]*>.*?</form> # form block
| <img\b[^>]*>.*?</img> # img block
| <onmouseover\b[^>]*>.*?</onmouseover> # onmouseover block
| <body\b[^>]*>.*?</body> # body block
)*+
)$
}isx';
if (preg_match($html_regex, $html_string))

Well what are you still have trouble with?

[baxr6]

specifically these

 

(eregi("\([^>]*\"?[^)]*\)", $secvalue)) ||
        (eregi("\"", $secvalue)) ||
        (eregi("forum_admin", $sec_key)) ||
        (eregi("inside_mod", $sec_key))) {

 

and if it will function as before.

[Garethp]

"~\([^>]*\"?[^)]*\)~i"

"~\"~i"

"~forum_admin~i"

"~inside_mod~i"

 

Try those in preg_match, then come back if you have some more problems

[baxr6]

might need to put it in code tags, i think its messed up

[Garethp]

"~\([^>]*\"?[^)]*\)~i"
"~\"~i"
"~forum_admin~i"
"~inside_mod~i"

 

Try those in preg_match, then come back if you have some more problems

Can someone (experienced) advise me how to convert the following from eregi to preg* functions

due I read that "eregi() gets deprecated with PHP 5.3"

 

// begin hacker defense - Thanks Kreuznacher | wurdzwurk

foreach ($_POST as $secvalue) {

if ((eregi("<[^>]*script.*\"?[^>]*>", $secvalue)) ||

(eregi("<[^>]*object.*\"?[^>]*>", $secvalue)) ||

(eregi("<[^>]*iframe.*\"?[^>]*>", $secvalue)) ||

(eregi("<[^>]*applet.*\"?[^>]*>", $secvalue)) ||

(eregi("<[^>]*window.*\"?[^>]*>", $secvalue)) ||

(eregi("<[^>]*document.*\"?[^>]*>", $secvalue)) ||

(eregi("<[^>]*cookie.*\"?[^>]*>", $secvalue)) ||

(eregi("<[^>]*meta.*\"?[^>]*>", $secvalue)) ||

(eregi("<[^>]*style.*\"?[^>]*>", $secvalue)) ||

(eregi("<[^>]*alert.*\"?[^>]*>", $secvalue)) ||

(eregi("<[^>]*form.*\"?[^>]*>", $secvalue)) ||

(eregi("<[^>]*php.*\"?[^>]*>", $secvalue)) ||

(eregi("<[^>]*<?.*\"?[^>]*>", $secvalue)) ||

(eregi("<[^>]*img.*\"?[^>]*>", $secvalue))) {

die ("There was a problem with your post. Pleae try removing any HTML you may have in it.");

}

}

// end hacker defense 

 

 

Appreciate advice here.

Thanks.
