更改PHP \ HTML中的日期输入格式

Question

I have troubles with date formatting.

<input type="text" pattern="\d{2}\-\d{2}\-\d{4}" name="username2">

$date = $_POST["username2"];
$result = shell_exec("grep -i 'SERVICE ALERT' /home/den/shell/today/logfile-$date-00.log");

In logfile-$date-00.log variable $date is written in format : mm-dd-yyyy (for example logfile-03-31-2014-00.log). But in my input, to grep logfile, I need to write date in format : dd-mm-yyyy.

How can I change dd-mm-yyyy input to mm-dd-yyyy file without renaming? Help please :)

Answer 1

you can change your input date format with date() try

$date = date('m-d-Y', strtotime($_POST["username2"])); //mm-dd-yyyy

or for dd-mm-yyyy

$date = date('d-m-Y', strtotime($_POST["username2"]));

and also change your shell_exec() with below code

$result = shell_exec("grep -i 'SERVICE ALERT' /home/den/shell/today/logfile-".$date."-00.log");
