Regular Expressions or no?

[Hameedullah]

I want to find any newline "\n" and replace it with <BR> only if it does not follow by certain HTML tags (eg <p>, <br>, etc) that would double up the spaces.

Can anyone help me what is the best way to go about this? Should i use regex's? if so then can you tell me how to write the pattern?

Cheers,
Hameed

<?php
echo [b]nl2br[/b]("foo isn't\n bar");
?>

nl2br doesn't replace the newlines, but because a browser just treats newlines as whitespace this should do what you're looking for

>>nl2br doesn't replace the newlines

i am confused at what u r trying to say.

this is from the manual:
>>Returns string with '<br />' inserted before all newlines.


Hameed try tihs:
$TheStr=preg_replace("/\n(<br>|<p>)/i","$1",$TheStr);
$TheStr=nl2br($TheStr);

to add more tags just add a | and add the tag. e.g. if u want to add <hr> to it then:
$TheStr=preg_replace("/\n(<br>|<p>|<hr>)/i","$1",$TheStr);

i am confused at what u r trying to say.

Hameed's requirement is to replace \n with <br>, I'm suggesting that the nl2br function is what he needs, because the browser will ignore the newlines anyway, and just insert <br /> beside them.

the <br /> is understood by browsers as <BR>, but is XHTML compliant. I appreciate that what I posted isn't what the OP requested, but might be a better solution for his requirements.

now what made u think that???


since hameed says:
>>I want to find any newline "\n" and replace it with <BR> only if it does not follow by certain HTML tags

and u say:
>>I appreciate that what I posted isn't what the OP requested, but might be a better solution for his requirements

i guess thats it.
