a thought a thread containing useful PHP code bits would be useful.
I'll start out with a useful way to assign strings using the heredoc syntax: $text=<<<EOF <html> blah blah blah $someVar blah blah blah </html> EOF; You can also echo heredoc strings this way too. To view arrays, use print_r($array). Including <pre> tags is good for viewing large arrays; i.e., echo '<pre>'; print_r($your_array); echo '</pre>'; |

This is a way to create a menu bar like the one above (i.e., Mind-Brain.com Forum -> Information Technology -> Web Programming -> PHP Pearls), and which I've now added to the top (on the left) of non-Forum pages.
// // $excArray should contain all files that should NOT be // included in your bookmarks. // Ex. index.php, success.php etc etc // $excArray=array( 'index.php', 'index.html', 'listing.php', ); if(!$path) { $dirs=explode('/',$_SERVER['PHP_SELF']); } else { $urlArray=parse_url($path); $dirs=explode('/',$urlArray['path']); } // // Home Page // Change the title and link text to suit // $op.="<a href=\"/\">Home</a> > "; foreach($dirs as $key => $val) { // // the numeric bit here can be removed if you do not have numeric // directories (I use them instead of dynamic urls) // if($val!= "" &&!in_array($val,$excArray)) { if ($oldval){ $op.=" > <a href=\"/$oldval$val/\">$val</a>"; $oldval.="$val/"; }else{ $op.="<a href=\"/$val/\">$val</a>"; $oldval="$val/"; } } } print "$op"; |

Here's a PHP Countdown script: the $bday variable contains the date to countdown to. at the moment it is set to (23, 59, 0, 4, 17, 2003) (which is 11:59pm, 17 April, 2003) numbers are: HOUR (24 hr), MINUTE, SECOND, MONTH, DAY, YEAR SO, for example, you wanted to countdown to new year 2006, it would be $bday = mktime(0, 0, 0, 1, 1, 2006); <? // change this for your date to countdown to $bday = mktime(23, 59, 0, 4, 17, 2003); print "Your countdown date is " . date("j F Y, g.i a", $bday) . ".<BR>"; print "You visited this page at " . date("j F Y, G.i:s", time()); $diff = $bday - time(); $days = ($diff - ($diff % 86400)) / 86400; $diff = $diff - ($days * 86400); $hours = ($diff - ($diff % 3600)) / 3600; $diff = $diff - ($hours * 3600); $minutes = ($diff - ($diff % 60)) / 60; $diff = $diff - ($minutes * 60); $seconds = ($diff - ($diff % 1)) / 1; print "Only $days days, $hours hours, $minutes minutes and $seconds seconds until your countdown date!"; ?> |
