Looping through directory and list files after sorting - php function


PHP Code for simply looping and listing the files names in a directory into a select box.


<select>
<?php

$logFolder="../csvfolder";
if ( $handle = opendir($logFolder) ) {
/* loop over the directory. */
while (false !== ($file = readdir($handle))) {
if( stripos( $file,".csv" ) > 0 )
echo "<option value=\"$file\">$file</option>\n";
}

closedir($handle);
}

?>
</select>


Here I am checking whether the file in the folder is a csv file, if it is a csv it is listed.




PHP function to loop through the files in a directory and list the file names after sorting it.


<ul>
<?php
$dir = "directory";
if ($handle = opendir ($dir)) {
while (false !== ($file = readdir ($handle))) {
if (preg_match ("/.inc$/i", $file)) {
$file = str_replace ("_", " ", $file);
$file = explode (".", $file);
$file = $file[0];
$filelist[] = trim ($file);
}
}
sort ($filelist);
reset ($filelist);
while (list ($key, $val) = each ($filelist)) {
print (" <li><a href=\"temp.php?type=$val\">$val</a></li>\n");
}
closedir ($handle);
}
?>
</ul>








A Php function you can use to list the files in the directory you specify, their type (dir or file) and whether they are hidden.

Modify it to do other things.


<?php
function listDirs($where){
echo "<table border=\"1\"><tr><td><b>Name</b></td><td><b>Type</b></td>";
echo "<td><b>Invisible (Hidden)?</b></td></tr>";
$itemHandler=opendir($where);
$i=0;
while(($item=readdir($itemHandler)) !== false){
if(substr($item, 0, 1)!="."){
if(is_dir($item)){
echo "<tr><td>$item</td><td>Directory</td><td>No</td></tr>";
}else{
echo "<tr><td>$item</td><td>File</td><td>No</td></tr>";
}
$i++;
}else{
if(is_dir($item)){
echo "<tr><td>$item</td><td>Directory</td><td>Yes</td></tr>";
}else{
echo "<tr><td>$item</td><td>File</td><td>Yes</td></tr>";
}
$i++;
}
}
echo "</table>";
}
?>


//Then call it like this.


<?php
listDirs(DIR);
?>


//Example:
<?php
listDirs("/tests/directorylisting");
?>
