how can i sort this alphabetically, and remove spaces? select list query

[antonyfal]

Hi i have a drop-down list this little piece is where i explode the comma deliminated words into an array..

 

everything works but i cant find a function to do the sort order of the value options? and also i get a blank space everytime.. as option and value?

<optgroup label=\"Others added\">";										
		$profile_languagegeneralrep = str_replace(', ', ',',$profile_languagegeneral); 
        $langwording = explode(',', $profile_languagegeneralrep);
        $langwording = array_unique($langwording);
        foreach($langwording as $langexi)				
	$languageLists .= "<option value=\"".$langexi.','."\">".$langexi."</option>";
	$languageLists .= "</optgroup>";
			}
		$languageLists.="</select>";		   	
		$output['LANGUAGELISTS']=$languageLists;

How about sort?

"";
$langwording = array_unique(array_map("trim", explode(",", $profile_languagegeneral)));
sort($langwording);
foreach ($langwording as $langexi) {...

Hi, thanks for the reply..

I haven't had the chance to test this yet-- does the "trim" remove the blank space/s?

i think the sort will work..

Best regards

trim — Strip whitespace (or other characters) from the beginning and end of a string : http://fi2.php.net/manual/en/function.trim.php . PHP.net manual is your friend.

The "blank space" as option and value is most likely the result of having a comma at the beginning or end of your original string. The explode() function splits the string on ALL occurrences of the delimiter. To prevent this from happening, remove the leading and/or trailing comma. You can do this with trim(). Based on the code from  requinix:

 

"<optgroup label=\"Others added\">";
$langwording = array_unique(array_map("trim", explode(",", trim($profile_languagegeneral, ','))));
sort($langwording);
foreach ($langwording as $langexi) {...
