How to upload a file using PHP ?

For uploading a file in PHP + MySQL, we have to use datatype as varchar(250) to store the filename and it's path.

Before uploading any photo or doc we must have to make our form tag as enctype. And inside the phpcode we must have to check weather the file is already exists in that location or not.

For Example. Table of Database is given
tblimagedemo

Data Type Column Name

id int PK Auto_Increment

photo varchar(250)

On Webpage file upload control is given in below image to choose file with button submit.

For that write HTML code.

<table>

<tr>

<td>Image</td>

<td>

</td>

</tr>

<tr>

<td>

</td>

</tr>

</table>

</form>

Write PHP code in head or body section.

<?php

if(isset($_POST['btnsubmit']))

{

if($_FILES['file']['error']>0)

{

echo"Error in uploading";

}

else

{

echo"upload:".$_FILES['file']['name']."<br>";

$i="image/".$_FILES['file']['name'];

if(file_exists("image/".$_FILES['file']['name']))

{

echo $_FILES['file']['name']."File is already Exists";

}

else

{

move_uploaded_file($_FILES['file']['tmp_name'],"image/".$_FILES['file']['name']);

echo "File is uploaded successfully";

}

if(empty($i))

{

echo "Upload your image";

}

else

{

$sql = "INSERT INTO `superstore`.`tblimagedemo` (`id`, `photo`) VALUES (NULL, '$i')";

if(mysqli_query($con,$sql))

{

echo"Record inserted";

}

Date Datatype in PHP with Different Date Format.

Date in PHP with Example code.

Date Datatype's syntax is the

date(format in string, time stamp);

Default format which the developer wants is dd/mm/yyyy we can do it by following code.

date("d/m/Y");

This code will print the current date with 05/04/2014

Formats a time and date according to the format string provided in the first parameter. If the second parameter is not specified, the current time and date is used.As shown in the above example.

date("m/d/Y");

This code will print the current date with 04/05/2014

The mktime() function returns the timestamp for the date and we can store the output of the function mktime() to any variable in php for printing suitable date.

Syntax of mktime() is given below

mktime(hour,minute,second,month,day,year,is_dst)

We can change the format of the date by mktime function.By providing the time stamp as a second argument in the date function.
if we want to print the date after 10 days then we can use below formatting.with the help of mktime and date.
hour=0
minite=0
second=0
month = m means current month April (4)
day = d+10 means 10 days will be added to the current date and
year = Y means current year (2014)

$dateten = mktime(0,0,0,date("m"),date("d")+10,date("Y"));
echo "The date after 10 days is ".date("d/m/Y", $dateten);

output : The date after 10 days is 15/04/2014

Here in above example the $dateten variable will print the date after 10 days as output.

Date Format

D
Instead of current date 05 if we have to print name of the day then use above char D.It will print first three letters of the current day.

date("D/m/Y");

This code will print the current date with SAT/04/2014

l (small l)
Instead of current date 05 if we have to print name of the day then use above char D.It will print name the current day.

date("l/m/Y");

This code will print the current date with Saturday/04/2014

M
Instead of current Month 04 if we have to print name of the month then use above char F.It will print first three letters of the current month.
date("d/M/Y");

This code will print the current date with 05/Apr/2014

F
Instead of current Month 04 if we have to print name of the month then use above char F.It will print name of the current month.

date("d/F/Y");

This code will print the current date with 05/April/2014

y
If we have to print the Current year's last two digits then use y.Year with two digits; e.g., “14”.

date("d/m/y");

This code will print the current date with 05/04/14
