PHP include() Statement

Description

The include() statement is used to include a php file in another file. This way you can write a piece of code in a php file and can use it to multiple files through  include() statement.

If a.php is a php script calling b.php with include() statement, and does not find b.php, a.php executes with a warning, excluding the part of the code written within b.php.

Syntax:

include('name of the php file with path');

Example:

File my_include.php:

<?php
$sports1 = "football";
$sports2 = "cricket";
?>

File myfile.php, which includes my_include.php :

<?php
include('my_include.php');
echo "I prefer&nbsp;".  $sports1 ."&nbsp;
than&nbsp;".  $sports2;
?>

Output:

I prefer football  than cricket

If the file within require statement is not available:

For example, if you write my-include.php (which is not available),like this:

<?php
include('myfile_include.php');
echo "I prefer&nbsp;". $sports1 ."&nbsp; than&nbsp;". $sports2;
?>

View the example of php include statement where included file is not present

You can see that it fails to meet the purpose of including the file myfile_include.php, but the script does not stop executing.

require() Statement

require() is identical to include() except upon failure. On failure it produce a fatal E_ERROR level error.

PHP: Tips of the Day

PHP: Convert one date format into another in PHP

The second parameter to date() needs to be a proper timestamp (seconds since January 1, 1970). You are passing a string, which date() can't recognize.

You can use strtotime() to convert a date string into a timestamp. However, even strtotime() doesn't recognize the y-m-d-h-i-s format.

PHP 5.3 and up

Use DateTime::createFromFormat. It allows you to specify an exact mask - using the date() syntax - to parse incoming string dates with.

PHP 5.2 and lower

You will have to parse the elements (year, month, day, hour, minute, second) manually using substr() and hand the results to mktime() that will build you a timestamp.

But that's a lot of work! I recommend using a different format that strftime() can understand. strftime() understands any date input short of the next time joe will slip on the ice. for example, this works:

$old_date = date('l, F d y h:i:s');         // returns Saturday, January 30 10 02:06:34
$old_date_timestamp = strtotime($old_date);
$new_date = date('Y-m-d H:i:s', $old_date_timestamp);
