I have these files in a directory and can easily list to a webpage
Daily_CD_20130902.xml Daily_CD_20130903.xml Daily_CO_20130902.xml Daily_CO_20130903.xml Daily_CU_20130902.xml Daily_CU_20130903.xml Daily_EQ_20130902.xml Daily_EQ_20130903.xml Daily_IR_20130902.xml Daily_IR_20130903.xml
However, i want to be selective and just select the most recent of each type, so instead of the whole list i want to display
Daily_CD_20130903.xml Daily_CO_20130903.xml Daily_CU_20130903.xml Daily_EQ_20130903.xml Daily_IR_20130903.xml
Is there an easy way to do this or do i need to take apart the filename, put the date in a date object and then use it to sort.
my current code is:
public function getFiles() {
//return String, form as HTML later
$return = "";
// create a resrouce pointing to the directory with the files in it on disk
$dir = opendir('DIRECTORY');
//path to that directory that is appended to the URL
$actualdir = 'PATH FROM WEBSERVER ROOT';
// read the directory looping over the files and populate to an array
while ($entryName = readdir($dir)){
$dirArray[] = $entryName;
}
//close the directory as we don't need it anymore
closedir($dir);
//make a note of how many items are in the directory
$indexCount = count($dirArray);
//loop through the files building up a list of links
for($index=0; $index < $indexCount; $index++) {
if($dirArray[$index] !="." && $dirArray[$index] !=".."){
$return .= "<a href='"."$actualdir".$dirArray[$index]."'>".$dirArray[$index]."</a><br/>";
}
}
return $return;
}
any help is appreciated as this is my first day of PHP
