note 47877 added to function.substr

(final) here's a useful algorithm for parsing page ranges. it simply does not register ranges like 40-48-54 or nonsensical input, but will register ranges like 38-40 and anything comma delimited. $pages = '34, 35, 36, 38-40, 40-48-54, sddjhhsdhkadsh, 93, 126'; $pageslen = strlen($pages); $j = 0; for ($i=0; $i<=$pageslen; $i++) {if (ereg('[0-9]', $pages{$i})) {$numbuff = $numbuff.$pages{$i};} elseif ($pages{$i} == ',') {if ($numbuff) {$page[] = $numbuff; $numbuff = '';} } elseif ($pages{$i} == '-') {$range[$j][0] = $numbuff; $numbuff = ''; $i++; do { if (ereg('[0-9]',$pages{$i})) {$numbuff = $numbuff.$pages{$i};} $i++; } while (ereg('[[0-9]', $pages{$i})); if (ereg('[^,[:space:]]', $pages{$i+1})) {do {$i++;} while (ereg('[^,[:space:]]', $pages{$i})); $range[$j] = ''; if (!$range) {$range = '';} $numbuff = ''; $i--; } else { $range[$j][1] = $numbuff; $numbuff = ''; $j++;} } } $page[] = $numbuff; print_r($page); print_r($range); ---- Manual Page -- http://www.php.net/manual/en/function.substr.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+47877 Delete -- http://master.php.net/manage/user-notes.php?action=delete+47877&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+47877&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+47877&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+47877&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+47877&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+47877&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+47877&report=yes Search -- http://master.php.net/manage/user-notes.php
