note 49308 added to function.glob

The example on this page will generate a warning if the glob function does not find any filenames that match the pattern. The glob function result will only be an array if it finds some files and the foreach statement requires its argument to be an array. By checking for the possibility that the result of the glob function may not be an array you can eliminate the warning. Here's a better example: <?php $matches = glob("*.txt"); if ( is_array ( $matches ) ) { foreach ( $matches as $filename) {    echo "$filename size " . filesize($filename) . "\n"; } } ?> ---- Manual Page -- http://www.php.net/manual/en/function.glob.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+49308 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+49308&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+49308&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+49308&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+49308&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+49308&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+49308&report=yes Search -- http://master.php.net/manage/user-notes.php
