1.2.796. No Direct Usage¶
The results of the following functions shouldn’t be used directly, but checked first.
For example, glob() returns an array, unless some error happens, in which case it returns a boolean (false). In such case, however rare it is, plugging glob() directly in a foreach() loops will yield errors.
<?php
// Used without check :
foreach(glob('.') as $file) { /* do Something */ }.
// Used without check :
$files = glob('.');
if (!is_array($files)) {
foreach($files as $file) { /* do Something */ }.
}
?>
1.2.796.1. Suggestions¶
Check the return of the function before using it, in particular for false, or array().
