<body>

PLEASE ENTER THE DATE MONTH AND YEAR <select name="days">

</select>

</select>

</select>

</form>

</body>

</html>

and php script is as below

<?php

$dd=$_POST[days];

$mm=$_POST[month];

$yy=$_POST[year];

$j=$dd."-".$mm."-".$yy.".".html;

echo $j;

$def_dir="/var/www/html/backup/$mm";

chdir ($def_dir);

print_r(glob($j));

?>

if a person search for particular day the script should display the report of that particular day plz i need a help

This is better suited for the php help forum. This doesn't have anything to do with OOP

Just to get you started:

<HTML>
<form action="search.php" method="POST">
<select name='days'>
  <?php
  for ($x=1;$x<=31;$x++){ // basic FOR loop to easily create the html
    echo "<option value='$x'>$x</option>";
  }
  ?>
<select name='month'>
  <?php
  for ($x=1;$x<=12;$x++){ 
    echo "<option value='$x'>$x</option>";
  }
  ?>
<select name='year'>
  <?php
  for ($y=2007; $y <= date('Y') ;$y++){ 
  // date('Y') returns the current 4-digit year. This will show all years from 2007 to the current year.
    echo "<option value='$y'>$y</option>";
  }
  ?>
<input type='submit' name='search' value='search'>
</form>
</HTML>

<?php
// search.php
$dd=$_POST[days];
$dd = str_pad($dd, 2, '0', 1); // If it is less than 2 characters long, add a 0 on the left side
$mm=$_POST[month];
$mm = str_pad($mm, 2, '0', 1); // If it is less than 2 characters long, add a 0 on the left side
$yy=$_POST[year];
$j=$dd . "-" . $mm . "-" . $yy . ".html";
echo $j;
$month = strtolower(date('M', strtotime("$yy$mm$dd 12:00:00"))); // A lot going on here
// strtolower makes the results all lowercase to match your 'mar' for march
// date('M', ...) returns the 3-letter form of month
// strtotime() is returning the unix timestamp for date() for the submitted date, at 12 noon.
$def_dir="/var/www/html/backup/$month";
?>

I've used some simpler functions here because if we used sprintf() you'd be in a corner crying (I say that because after a year, I finally figured out how to use it, otherwise I was crying). So yeah, there you go. I didn't test it, I just wrote it, but it should get you going in the right direction.

had a little fidle to learn str_pad

my long example

<?php

if($_POST['submit']){

$day=$_POST['day'];
$month=$_POST['month'];
$year=$_POST['year'];

$res=$_POST['res'];

$res=$day.$month.$year;

if($res=='01112008'){

echo"<center>Hi there m8 correct date!</center>";

}else{

echo "<center>Incorrect Date!</center>";
} 
}

$year=range(2008,2020);
$day=range(1,31);
$month=range(1,12);

echo"<center>";

echo"<form method='post' action=''>

<p></p>
Please enter a search via date!
<p></p>

<select name='day'>";
foreach($day as $days){
$days=str_pad($days,2,'0',STR_PAD_LEFT);
echo"<option value='$days'>$days</option>";
}

echo "</select>";

echo"<select name='month'>";
foreach($month as $months){
$months=str_pad($months,2,'0',STR_PAD_LEFT);
echo"<option value='$months'>$months</option>";
}

echo "</select>";

echo"<select name='year'>";
foreach($year as $years){
echo"<option value='$years'>$years</option>";
}


echo "</select>";

echo"<p></p><input type='submit' name='submit' value='Send'>";

echo"</form></center>";

?>

$months=str_pad($months,2,'0',STR_PAD_LEFT);

While that works for str_pad(), luckily, php.net states it is expecting an integer for STR_PAD_LEFT.

The only reason I mention this is that some other functions, as I learned putting a book together (see my sig in a few days, once reviews are back), they state they take an integer and they only accept the string version of the flag, and other functions accept only an integer that represents one of the flags.

On a sidebar, I always forget about range, I wonder which loop is faster, the for() or foreach() with range.

Oh heck, ran a test:

<?php
$time = microtime(1);
$month = range(1,1000);
foreach($month as $months){
  $months=str_pad($months,2,'0',1);
}
$time = number_format(microtime(1)-$time, 6);
echo "$time seconds to complete FOREACH with RANGE.";

$time = microtime(1);
for($month=1;$month<=1000;$month++){
  $months=str_pad($month,2,'0',1);
}
$time = number_format(microtime(1)-$time, 6);
echo "$time seconds to complete FOR loop.";
?>

Results:

0.002322 seconds to complete FOREACH with RANGE.

0.002290 seconds to complete FOR loop.

I ran it a bunch of times, and while the values varied, FOR was 95% of the time faster, about 2%-25% faster.

Of course, this is less than 1/1000th of a second, and we are doing a loop of 12 values, not 1000... so it's a moot point. Just thought I would share.
