Use, mysql_real_escape_string

 

it's not working ???????????????

 

If you are inserting into db, could solve
However, try these functions
html_entities() or htmlspecialchars() or html_entity_decode()

You will have a solution in one of them

 

echo '<input type="text" value="'.htmlspecialchars( $OLD_TEXT ).'" />';

Code (markup):

And if you see slashes alongwith quotes, use

if(get_magic_quotes_gpc())
   $OLD_TEXT = stripslashes($OLD_TEXT);

Code (markup):

 

thanks, I will try
