I want to replace double spaces with single spaces.

I have been able to do this before :

 php Syntax (Toggle Plain Text) 
$new_string=str_replace("  "," ",$old_string)
$new_string=str_replace("  "," ",$old_string)

this worked or I thought it did anyway with other strings but I'm guessing there's something in the problem string that I'm not seeing

anyway to get to the point this is what I have:

 php Syntax (Toggle Plain Text) 
//  $cpu_type  comes in from MySQL database as: "Genuine Intel  T2300" - note
//             the double space after Intel
 
echo $cpu_type;
 
$cpu_type = str_replace("\t"," ",$cpu_type);
$cpu_type = str_replace("  "," ",$cpu_type);
 
echo $cpu_type;
//  $cpu_type  comes in from MySQL database as: "Genuine Intel  T2300" - note
//             the double space after Intel

echo $cpu_type;

$cpu_type = str_replace("\t"," ",$cpu_type);
$cpu_type = str_replace("  "," ",$cpu_type);

echo $cpu_type;

the code above echoes the same before and after the str_replace command. What am I missing? it's definitely two spaces but as you can see I've even tried replacing a tab in case that's what it was... Are there any other characters it could be???

Are you positive that it's what comes from the database? Output it and then check the HTML (not what appears in the browser). This is because it could be using " " for a space, which appears to be a space in your browser, but is not the case in the data.

There could also be a newline, or something else. So make sure you're comparing it to the outputted HTML.
