#define ETIMEDOUT 110 /* Connection timed out */ ...But here's the whole list on my Linux system ( /usr/include/asm-generic/errno.h ):

The @ operator suppresses error messages. A usual example is:
<?php $v = @$a['non-existing-key']; ?>which suppresses the "undefined index" PHP notice. Another example is:
<?php @include('non_existent_file'); ?>In this case, @ not only suppresses error messages for non-existing file, it also suppresses any error messages coming from the included file when it does exist. Create file test.php :
<?php @include('test.inc'); ?>Create test.inc :
<?php <?php garbage ?>The "undefined constant" PHP notice message is suppressed by @ .

Variable Meaning $_ The default or implicit variable. @_ Within a subroutine the array @_ contains the parameters passed to that subroutine. $a, $b Special package variables when using sort() $<digit> Contains the subpattern from the corresponding set of capturing parentheses from the last pattern match, not counting patterns matched in nested blocks that have been exited already. $. Current line number for the last filehandle accessed. $/ The input record separator, newline by default. $| If set to nonzero, forces a flush right away and after every write or print on the currently selected output channel.
