I tried this code but i misplaced an "}" and the script displays files outside from my
directory also and not able to understand why.
Can anyone explain why
Code with misplaced *}*:
the misplaced *}* is on 8th line which needs to come after
if(is_dir("$dir/$file")) {
readall("$dir/$file");
}
CODE:::::
<?php
function readall($dir) {
if(file_exists($dir)) {
$dr=opendir($dir) or die ('cannot open');
while($file=readdir($dr)) {
if($file!='.' && $file!='..') {
echo "$dir/$file" ."<br>";
}
if(is_dir("$dir/$file")) {
readall("$dir/$file");
}
}
closedir($dr);
}
}
if (file_exists('.')) {
readall('.');
}
?>
Corrected code:
<?php
function readall($dir) {
if(file_exists($dir)) {
$dr=opendir($dir) or die ('cannot open');
while($file=readdir($dr)) {
if($file!='.' && $file!='..') {
echo "$dir/$file" ."<br>";
if(is_dir("$dir/$file")) {
readall("$dir/$file");
}
}
}
closedir($dr);
}
}
if (file_exists('.')) {
readall('.');
}
?>
