note 125129 added to function.getopt

getopt() simply ignores unnecessary options specified in argv. Many times, it does not work well to handle errors in command line. A package PEAR::Console_Getopt can handle this problem, but it requires additonal installation. GNU getopt(1) does well at shell level. Following is my extended getopt() can detect unnecessary options: <?php function getoptex($sopt, $lopt, &$ind) { global $argv, $argc; $sopts = getopt($sopt, $lopt); $sopts_cnt = count($sopts); // single-option count based on original sopt $asopt = $sopt . implode("", range("a", "z")) . implode("", range("A", "Z")) . implode("", range("0", "9")); $asopts = getopt($asopt, $lopt); $asopts_cnt = count($asopts); // actual single-option count including all single options even if is not listed as sopt $lopt_trim = array(); foreach ($lopt as $o) { $lopt_trim[] = trim($o, ":"); } $alopts_cnt = 0; $alopts_flag = true; for ($i = 1; $i < $argc; $i++) { if ($argv[$i] === "--") { // end of option break; } if (strpos($argv[$i], "--") === 0) { // actual long-option $alopts_cnt++; $o = substr($argv[$i], 2); if (! in_array($o, $lopt_trim)) { // but it is not listed as lopt $alopts_flag = false; } else { if (in_array(($o . ":"), $lopt)) { // if the option requires value $i++; // assume next is the value if ($i >= $argc) { // and the value is missing $alopts_flag = false; break; } } } } } //var_dump($sopts, $asopts, $lopts, $alopts_cnt, $alopts_flag); if ($sopts_cnt != $asopts_cnt || (! $alopts_flag)) { return false; } else { return getopt($sopt, $lopt, $ind); } } ?> ---- Server IP: 45.112.84.4 Probable Submitter: 103.51.166.36 (proxied: 220.100.115.55) ---- Manual Page -- http://php.net/manual/en/function.getopt.php Edit -- https://master.php.net/note/edit/125129 Del: integrated -- https://master.php.net/note/delete/125129/integrated Del: useless -- https://master.php.net/note/delete/125129/useless Del: bad code -- https://master.php.net/note/delete/125129/bad+code Del: spam -- https://master.php.net/note/delete/125129/spam Del: non-english -- https://master.php.net/note/delete/125129/non-english Del: in docs -- https://master.php.net/note/delete/125129/in+docs Del: other reasons-- https://master.php.net/note/delete/125129 Reject -- https://master.php.net/note/reject/125129 Search -- https://master.php.net/manage/user-notes.php
