Question

This is the code I used to get array key with single quote mark:

// the array with key and value
$savedFilesIds = array("F564574"=>"none","F456735"=>"none","F4777"=>"none")   

//$file_ids = implode(',',array_keys($savedFilesIds));  // without adding single quote mark for keys

// the way I used to adding single quote mark for keys

$file_ids = array();

foreach($savedFilesIds as $key=>$value){
    $item = '\''.$key.'\'';  // adding single quote mark here
    array_push($file_ids , $item);  // and then adding to array  
}

$file_ids = implode(',',$file_ids);  // get the key with single quote mark

echo $file_ids;

Is there other better way to make it more effective?

Answer 1

$quotedIds = array_map(create_function('$a', 'return "\'$a\'";'), array_keys($savedFilesIds));
