Errors are hints from compiler for the programmer to correct. But sometimes we face some unwanted or dynamic error. For example,
$content = filegetcontents(http://www.twitter.com/feed/234);
Here , the url is invalid, or the server of the url is down , PHP shows Warning: Failed to open stream or file access is disabled.
Use @ in front of such function never shows any warning message.
Eg: $content = @filegetcontents(url here) or die (‘Sorry , cannot access the url’);
Another method is runtime PHP ini editing
*ini_set *(‘display_errors’, 0);
//write the code which may cause error here
*ini_set *(‘display_errors’, 1);
But , these things are not recommended. Only for unavoidable situations.
