preg_replace !!

[teamer]

Hi all

 

i have text in database with the following stuff > and < and stuff like that .

well guests enter text that is saved to the database , and when it is printed out i don't want it to be parsed so converting all HTML entities to > and < is enough .

 

BUT

 

i want to allow some HTML tags to be converted back to normal

like <font size=4>text</font>

 

so i wrote the following regex where

$alowed_ones='font|b|center|i|a';

 

$data=preg_replace('/(<)('.$alowed_ones.')((\s)(.*))?(>)(.*)(<\/)('.$alowed_ones.')(>)/ims' , 
						'<\\2\\3>\\7</\\9>',
						$data,-1);

 

but for example if i $data was

<center><a href="fF">Xx"</a></center>

 

only the <center></center> is back to normal and the <a> tag is not parsed unless i run the preg_replace again !!!

any way to do it without having to call it back ???

 

plz help
