I've got PHP back today.

Made an instance of PHP

is a perpetual calendar of PHP

Call Date () and use of loop structure

It's a simple interface, but the basic function is this.

Don't say much nonsense on the code

PHP$year=Empty($_get[' Y '])?Date("Y"):$_get[' Y ']; $mon=Empty($_get[' m '])?Date("M"):$_get[' m ']; Echo"$yearYears$mon} Month ; ?> <table width= "@" border= "1" > <tr> <th> Sunday </th>                <th> Monday </th> <th> Tuesday </th> <th> Wednesday </th>            <th> Thursday </th> <th> Friday </th> <th> Saturday </th> </tr> <?PHP$day=Date("T",Mktime(0,0,0,$mon, 1,$year)); $w=Date("W",Mktime(0,0,0,$mon, 1,$year)); $XQ= 1;  while($XQ<=$day) {                     Echo"<tr>";  for($i= 0;$i<= 6;$i++) {                     if($XQ>$day|| ($w>$i&&$XQ==1)) {                           Echo"<td>&nbsp;</td>"; }Else{                          Echo"<td>{$XQ}</td> "; $XQ++; }                    }                     Echo"<tr>"; }                Echo"</table>; $nyear=$year;//next year                $pyear=$year;//last year                $nmon=$mon+1; $pmon=$mon-1; if($nmon>12) {                    $nyear=$year+1; $nmon=1; }                if($pmon<1) {                    $pyear=$year-1; $pmon=12; }                Echo"<a href= ' date.php?y={$pyear}&m={$pmon} ' > Last month </a> '; Echo"&nbsp;&nbsp;&nbsp;&nbsp;"; Echo"<a href= ' date.php?y={$nyear}&m={$nmon} ' > Next month </a> '; ?> </center></body>
Above the.
Empty (xx1)? xx2:xx3;
is a ternary operator
Presumably, it means
If the xx1 is a value then execute xx2, if xx1 is empty then execute xx3;
And the use of empty.
