note 88081 added to function.rename

This is an update to the code provided by dev at islam-soft dot com, which renames all files in a directory with a given extension to have a different extension. I updated four things: Most important, added a check to make sure the extension matched ONLY the end of the filename (the original caused me a number of headaches when it started matching things in the middle of filenames instead of at the end where a proper extension belongs), 2nd added some feedback about what is going on, if you choose verbose mode=TRUE, 3rd added the "testing" parameter so you can do a test run before committing for real, 4th added an error message if a rename fails. parameter 1 : the directory name parameter 2 : the first extension which we want to replace parameter 3 : the new extension of files parameter 4 : verbose? (true/false) parameter 5 : testing? (true/false)--if true, won't actually rename anything; if you do verbose=TRUE and testing=TRUE you can see what will happen before committing to it with testing=FALSE. Return is the number of files renamed. for a simple usage call the function : changeext('my/directory', 'html', 'php', false, false); This changes every file name with extension html into php in the directory my/directory <?PHP //changes files in $directory with extension $ext1 to have extension $ext2 //note that if file.ext2 already exists it will simply be over-written function changeext($directory, $ext1, $ext2, $verbose = false, $testing=true) { if ($verbose && $testing) { echo "Testing only . . . <br />";} $num = 0; if($curdir = opendir($directory)) { if ($verbose) echo "Opening $directory . . .<br />"; while($file = readdir($curdir)) { if($file != '.' && $file != '..') { $srcfile = $directory . '/' . $file; $string = "$file"; $str = strlen($ext1); $str++; $newfile = substr($string, 0, -$str); $newfile = $newfile.'.'.$ext2; $dstfile = $directory . '/' . $newfile; if (eregi("\.$ext1". '$' ,$file)) { # Look at only files with a pre-defined extension, '$' ensures the ext is only at they end of the filename //I think the next two lines are unnecessary but they //don't hurt anything so I'm leaving them $fileHand = fopen($srcfile, 'r'); fclose($fileHand); if (!$testing) { $result=rename($srcfile, $dstfile ); if (!$result) echo "ERROR renaming $srcfile -> $dstfile<br />"; } if ($verbose) echo "$srcfile -> $dstfile<br />"; } if(is_dir($srcfile)) { $num += changeext($srcfile, $ext1, $ext2, $verbose, $testing); } } } closedir($curdir); } return $num; } $testing=true; $verbose=true; //example usages, first run with $testing set to false, then change $testing to true to do them for real: //changeext('your/directory', 'php', 'html', $verbose, $testing); //changeext('your/directory', 'html', 'php', $verbose, $testing); ---- Server IP: 208.69.120.35 Probable Submitter: 68.93.11.176 ---- Manual Page -- http://www.php.net/manual/en/function.rename.php Edit -- https://master.php.net/note/edit/88081 Del: integrated -- https://master.php.net/note/delete/88081/integrated Del: useless -- https://master.php.net/note/delete/88081/useless Del: bad code -- https://master.php.net/note/delete/88081/bad+code Del: spam -- https://master.php.net/note/delete/88081/spam Del: non-english -- https://master.php.net/note/delete/88081/non-english Del: in docs -- https://master.php.net/note/delete/88081/in+docs Del: other reasons-- https://master.php.net/note/delete/88081 Reject -- https://master.php.net/note/reject/88081 Search -- https://master.php.net/manage/user-notes.php
