note 110149 added to domdocument.savehtmlfile

Not mentioned in the documentation is the fact that using DOMDocument::saveHTMLFile() will automatically overwrite the contents if an existing file is used - with no notice, warning or error thrown. Make sure you check the filename before using this function so that you don't accidentally overwrite important files. Example: <?php $file = fopen('test.html', 'w'); fwrite($file, 'this is some text'); fclose($file); $doc = new DOMDocument(); $doc->formatOutput = true; $doc->loadHTML('<html><head><title>Test</title></head><body></body></html>'); $doc->saveHTMLFile('test.html'); // test.html /* <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Test</title> </head> <body></body> </html> */ ?> If you're dynamically generating a series of pages using DOMDocument objects, make sure you are also dynamically generating the file or directory names using something that can't easily be confused for an existing file/folder, or check if the desired path already exists before saving so that you don't accidentally delete previous files. ---- Server IP: 69.147.83.199 Probable Submitter: 94.216.97.37 ---- Manual Page -- http://www.php.net/manual/en/domdocument.savehtmlfile.php Edit -- https://master.php.net/note/edit/110149 Del: integrated -- https://master.php.net/note/delete/110149/integrated Del: useless -- https://master.php.net/note/delete/110149/useless Del: bad code -- https://master.php.net/note/delete/110149/bad+code Del: spam -- https://master.php.net/note/delete/110149/spam Del: non-english -- https://master.php.net/note/delete/110149/non-english Del: in docs -- https://master.php.net/note/delete/110149/in+docs Del: other reasons-- https://master.php.net/note/delete/110149 Reject -- https://master.php.net/note/reject/110149 Search -- https://master.php.net/manage/user-notes.php
