i have tried below method.

str_replace("\n", "", $key); 

but not worked.

any suggestions..?

thanks

try

$order   = array("\r\n", "\n", "\r"); $replace = '';      $final = str_replace($order, $replace, $str); var_dump($final); 

note : because str_replace() replaces left right, might replace inserted value when doing multiple replacements. processes \r\n's first aren't converted twice.
