We given php code for Checking directory and deleting one day old files from folder using php, from folder in windows or linux through php language. For deleting the files from folder in any system (windows or linux). I created the PHP script for deleting the old files from system.

deleting one day old files from folder using php
/***************** Delete one day old files ****************/
$dir = "C://Inetpub/vhosts/yourdomain/tmpfiles";
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while ($file = readdir($dh)) {
if(!is_dir($dir.$file)) {
if (filemtime($dir.DIRECTORY_SEPARATOR.$file) < strtotime('-1 days')) { //if 1 days old, delete
<div id=":1o">echo "Deleting $dir.$file (old)\n";
unlink($dir.$file);
}
}
}
} else {
echo "ERROR. Could not open directory: $dir\n";
}
} else {
echo "ERROR. Specified path is not a directory: $dir\n";
}
closedir($dh);
// Above script is platform independent.</div>
When we use the mobile download we always get the wma files as song file. If you want to convert wma files to mp3 file. For that I written the simple PHP sciprt for converting the wma files through php scirpt.
convert the wma files through php script in linux
Use the following scirpt.
<?php
// Script made for convertion of .wma to .M3 Converter (media conversion) in Linux
//You need the mplayer and lame installted in your linux OS
set_time_limit(0);
ReadDirs('/var/www/html/songs/wmamp3/');
function ReadDirs($dir){
if ($handle = opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != ".." && $file != "Thumb.db") {
$info = pathinfo($file);
if($info['extension']=='wma') {
$mp3_file = str_replace('.wma','',$file);
$cmd = "mplayer -vo null -vc dummy -af resample=44100 -ao pcm:waveheader '".$dir.$file."';lame -m s -V 3 audiodump.wav;mv audiodump.wav.mp3 '".$dir."mp3/".$mp3_file.".mp3';rm -f audiodump.wav";
system($cmd);
}
}
}
closedir($handle);
}
}
?>
Above script will take wma files from folder and convert all files to mp3 files.
I am using the bluehost for my some sites hosting. For sending emails I used the SMTP service which is provided by bluehost.
Bluehost : Mailer Error: SMTP Error: Could not connect to SMTP host
I used the PHPmailer in my website for sending email. When I tried to use the bluehost SMTP I always got the following error message.
Mailer Error: SMTP Error: Could not connect to SMTP host.”
I solved this issue. I created the following function.
<?php
include("class.phpmailer.php");
function mail_new($fun_to,$fun_subject,$fun_body,$fun_header,$fun_from,$fun_cc){
$mail = new PHPMailer();
$mail->IsSMTP(); // set mailer to use SMTP
$mail->Host = "mail.eparinay.com"; // specify main and backup server
//$mail->SMTPSecure = "ssl"; // sets the prefix to the servier
$mail->SMTPAuth = true; // turn on SMTP authentication
$mail->Username = "support@purabtech.in"; // SMTP username
$mail->Password = "YOURPSSSWORD"; // SMTP password
$mail->Port = 26;
$mail->From = $fun_from;
$mail->FromName = "eparinay.com";
$mail->AddAddress($fun_to);
$mail->AddReplyTo($fun_from, $fun_from);
if($fun_cc!=""){
$mail->AddAddress($fun_cc);
}
$mail->WordWrap = 50; // set word wrap to 50 characters
//$mail->AddAttachment("/var/tmp/file.tar.gz"); // add attachments
//$mail->AddAttachment("/tmp/image.jpg", "new.jpg"); // optional name
$mail->IsHTML(true); // set email format to HTML
$mail->Subject = $fun_subject;
$mail->Body = $fun_body;
//$mail->AltBody = "This is the body in plain text for non-HTML mail clients";
if(!$mail->Send())
{
echo "Message could not be sent. <p>";
echo "Mailer Error: " . $mail->ErrorInfo;
exit;
}
}
?>
Where you want to use the mail you just need to include the above script and call the “mail_new” function for sending email through bluehost.
