[PHP] replacing multiple spaces with one

2002-07-15 Thread David Russell 

Hi all

(easy one - I think)

I need to replace all instances of multiple spaces in a string with a 
single space.

I tries the following:
   $ArticleText = str_replace('  ', ' ', $ArticleText);
but if I have four spaces, I am left with two - this is wrong...

I am sure that I am really looking for a ereg_replace or preg_replace, 
but having no c/perl programming background, I do not know either perl 
or standard regex syntax.

Could someone tell me what the correct ereg/preg expression for this 
would be? I would also like a pointer to regex syntax, if someone knows 
offhand.

Thanks

David R

Hellorgh !!

$ArticleText = ereg_replace([[:space:]].*,  , $ArticleText);
Should be fine... But AFAIK, using preg_replace should be faster, but I
don't know the exact syntax to solve your probem :-(

  $ArticleText = preg_replace('/ +/', ' ', $ArticleText);

This replaces instances of one or more space with a single space.

The manual?
