Converting ampersands with str_replace
We have a news site, I am trying to set up an str_replace to convert the occurences where & is pulled from the database into standards friendly & (with the user still seeing &)
What happens is I get the following examples outputting on the visible site:
Changing World". The report
Copper & Gold
instead of the expected space or ampersand. The data is being pulled from a mysqldb with text fields. Where am I going wrong?
My code is:
function textfix($text){
$find = array('&', '<br>');
$replace = array('&', '<br />');
$newtext = str_replace($find, $replace, $text);
return $newtext;
}
the html stuff is:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-gb" lang="en-gb" dir="ltr">开发者_如何学C;
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
this has nothing to do with however if you have in your $text it will be changed to &nbsp;
also tell us what do you see in source-code of that html snippet
I strongly suggest that you use htmlentities() or htmlspecialchars() functions instead of trying to convert the ampersands.
using str_replace() will tell your program to mercilessly covert any & to & even in places where you need it, like with or whatever.
I'd suggest using preg_replace() and using regular expressions such as /&[^\w]/ to make sure you're only replacing independent ampersands.
using preg_replace() you can use the arrays as normal, and the parameters are the same as with str_replace(), but you should use regular expressions as the string values of the find array.
See the PHP manual for more details.
