string replace upper case to lowercase

[vinpkl]

hi

my select options are getting echo as upper case

<select>
<option><? echo strtoupper($row['category_name']); ?></option>
</select>

there are some option names that contain "&" sign. So I am replacing that sign with "&"

$row['category_name'] = str_replace("&", "&", $row['category_name']); 

but this outputs "&amp" as uppercase "&AMP" which gives error while validating the code

WALL & CAR CHARGER

how can i have "&amp" in lowercase and rest in uppercase

<select> 
<option><? echo str_replace('&AMP;', '&amp;', strtoupper($row['category_name'])); ?></option> 
</select>

Although it would be better to replace & with & /AFTER/ you've converted the text to uppercase; escaping is always the last thing you should do, for exactly the reason you're asking this question

So, better would be:

<select> 
<option><? echo htmlentities(strtoupper($row['category_name']), ENT_COMPAT, 'UTF-8', false); ?></option> 
</select>

and then remove the part where you replace & with &

So, better would be:

<select> 
<option><? echo htmlentities(strtoupper($row['category_name']), ENT_COMPAT, 'UTF-8', false); ?></option> 
</select>

thanks scallio

this option is much better and works perfect
