php: upload file- with same name from client to server

2010-10-06T21:40:00.001-07:00

HTML CODE:
-------------------------------------------------------------------------------

-------------------------------------------------------------------------------
PHP CODE
=============================================
PHP Code:

$target_path = "uploads/";

$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['uploadedfile']['name']).
" has been uploaded";
} else{
echo "There was an error uploading the file, please try again!";
}

=============================================
Here is a brief description of the important parts of the above code:

* enctype="multipart/form-data" - Necessary for our to-be-created PHP file to function properly.
* action="uploader.php" - The name of our PHP page that will be created, shortly.
* method="POST" - Informs the browser that we want to send information to the server using POST.
* input type="hidden" name="MA... - Sets the maximum allowable file size, in bytes, that can be uploaded. This safety mechanism is easily bypassed and we will show a solid backup solution in PHP. We have set the max file size to 100KB in this example.
* input name="uploadedfile" - uploadedfile is how we will access the file in our PHP script.

Save that form code into a file and call it upload.html. If you view it in a browser it should look like this:
-----------------------------------------
The $_FILES array is where PHP stores all the information about files. There are two elements of this array that we will need to understand for this example.

* uploadedfile - uploadedfile is the reference we assigned in our HTML form. We will need this to tell the $_FILES array which file we want to play around with.
* $_FILES['uploadedfile']['name'] - name contains the original path of the user uploaded file.
* $_FILES['uploadedfile']['tmp_name'] - tmp_name contains the path to the temporary file that resides on the server. The file should exist on the server in a temporary directory with a temporary name.

Now we can finally start to write a basic PHP upload manager script! Here is how we would get the temporary file name, choose a permanent name, and choose a place to store the file.

Using floor and time to calculate number of days elapsed from UNIX timestamp

2010-06-10T02:07:00.000-07:00

Finding out the number of days elapsed from a UNIX timestamp is actually pretty straightforward. If you only know two dates then first you’ll need to convert the date to a UNIX timestamps and then subtract the most recent timestamp from the older timestamp like this:
$old_timestamp = 1102971600;
$elapsed_seconds = time() - $old_timestamp;
print ‘Seconds elapsed since ‘ . date(“m-d-Y H:i:s”,$old_timestamp) . “: $elapsed_seconds”;
?>

Now, let’s convert those seconds to days using the floor() function, by just adding the following code to the code above:
/*
divide #seconds by 60 for minutes
divide #of minutes by 60 for hours
divide #of hours by 24 for days
use floor to get integer for day
*/
$elapsed_days = floor(($elapsed_seconds / 60) / 60 / 24);
print “
Number of days elapsed: $elapsed_days”;

number_format

(PHP 4, PHP 5)

number_format — Format a number with grouped thousands

string number_format ( float $number , int $decimals , string $dec_point , string $thousands_sep )
----------------------------------------------------------------------------------------------

number

The number being formatted.
decimals

Sets the number of decimal points.
dec_point

Sets the separator for the decimal point.
thousands_sep

Sets the thousands separator.

Only the first character of thousands_sep is used. For example, if you use bar as thousands_sep on the number 1000, number_format() will return 1b000.

----------------------------------------------------------------------------------------------

Example #1 number_format() Example

For instance, French notation usually use two decimals, comma (',') as decimal separator, and space (' ') as thousand separator. This is achieved with this line :

$number = 1234.56;

// english notation (default)
$english_format_number = number_format($number);
// 1,235

// French notation
$nombre_format_francais = number_format($number, 2, ',', ' ');
// 1 234,56

$number = 1234.5678;

// english notation without thousands seperator
$english_format_number = number_format($number, 2, '.', '');
// 1234.57

?>

below is the dummy data.
By giving the box a set height, you ensure that it does not expand or contract based on the
content it holds. If there is more content than the box can hold, the scrollbar will automatically
appear, allowing you to scroll through the whole text, as you see in Figure

Now define the stream selector. First, the size of the box is declared (here it is a square
300×300 pixels), and some padding is declared to ensure the content does not touch the border.
Most importantly, the overflow property is given the auto value.
Note that for this example, you will need to paste plenty of content into this container to
see the effect of the overflow, such as masses of Lorem Ipsum text. With that taken care of, we
can move on to the nifty styling.
