[RESOLVED] Need help with finding string

[rakuci]

Hi I need some problem with finding a part of string and changing it.

$str='LOREM IPSUM DOLOR SIT AMET CONSECTETUER IPSUM RIDICULUS ÉST PURUS'; 

I want to find the

É

and replace it with

É

so the word can be

$str='LOREM IPSUM DOLOR SIT AMET CONSECTETUER IPSUM RIDICULUS ÉST PURUS'; 

Thanx in advance

in simplest form you could just use str_replace

$newstring = str_replace("EACUTE", "Eacute", $str);

The problem is that I don't know that this word is going to be always É I'm getting the input from users and the data is coming in UPPERCASE I need to leave the string in uppercase only what starts with & and ends with ; I need to change it to ucfirst in this case É sometimes is Á and has to be Á

You are going to need to use preg_replace instead. This will allow you to use regular expressions to find/replace the strings you want to match.

you might also enjoy preg_replace_callback() Here is an example using it:

$str='LOREM IPSUM DOLOR SIT AMET CONSECTETUER IPSUM RIDICULUS ÉST PURUS'; 
$pattern = '/&[A-Z]+;/';

function fixHTMLCode($matches) {
   $str = preg_replace('/[^A-Z]/','',$matches[0]);
   $str = ucfirst(strtolower($str));
   return '&'.$str.';';
}

$newstr = preg_replace_callback($pattern,'fixHTMLCode',$str);
echo $str .'<br>'. $newstr;
