Hits count of a site using PHP

Suggestion for Hit count:

1. Create table to store the
hit counts into Database.

2. That table having the fields like
(a.) auto_increment_id (Primary Key)
(b.) file_name
(c.) user_ip_address
(d.) date_time_visit

3. Write an INSERT query to insert a record into the Database
Query: INSERT INTO table_name
SET file_name = 'VALUE1',
user_ip_address = 'VALUE2',
date_time_visit = 'VALUE3'

VALUE1 -- basename($_SERVER['PHP_SELF'])

VALUE2 -- $_SERVER['REMOTE_ADDR']

VALUE3 -- date('Y-m-d H:i:s')

4. VALUE1 is used to store for which filename visited by the user

5. VALUE2 is used to store the IP address of the visited user

6. VALUE3 is used to store the visited time of the user

7. Write the INSERT in (STEP 3) on your common areas
i.e. Header or Footer or leftpanel, or other regions loaded every time on every files in our site

8. If you want Total number of hits of all the files i.e. our entire site ?

Query : SELECT count(auto_increment_id) FROM tablename

this query answers for this question

9. Total number of hits for a particular file i.e. login.php

$current_filename = basename($_SERVER['PHP_SELF']);

Query: SELECT count(auto_increment_id) FROM tablename WHERE filename = '$current_filename';

this query answer for this question

Conclusion:
I hope you got some idea about getting the hit count using PHP..

Encrypt vs Decrypt using PHP

md5() - Message Digest Algorithm:

md5 -- Calculate the md5 hash of a string

Calculates the MD5 hash of str using the RSA Data Security, Inc. MD5 Message-Digest Algorithm, and returns that hash. The hash is a 32-character hexadecimal number.

$msg = "Evergreenphp123";
$encrypted_text = md5($msg);
echo "
Plain Text : ";
echo $msg;
echo "
Encrypted Text : ";
echo $encrypted_text;
?>

Note :

Once we encrypted the string using MD5() then we can't able to decrypt, we can again use the encrption of
the given string instead of decryption using below example.

Example :

$str = 'apple';

if (md5($str) === '1f3870be274f6c49b3e31a0c6728957f') {
echo "Valid string";
} else {
echo "Invalid string";
}
?>

Something about MD5:
- MD2 is a cryptographic hash function developed by Ronald Rivest in 1989.
- MD4 is a message digest algorithm (the fourth in a series) designed by Professor Ronald Rivest of MIT in 1990.
- MD4 is also used to compute NT-hash password digests on Microsoft Windows NT, XP and Vista.
- MD4 Weaknesses were demonstrated by Den Boer and Bosselaers in a paper published in 1991.
- MD5 was designed by Ron Rivest in 1991 to replace an earlier hash function, MD4.

Applications of MD5:

1. Encrypting the users password at Registration
2. Administrator itself not able to see the users password
3. Encrypting the users Activation code at the time of Registration


URL Encrypt and Decrypt

urlencode() -- URL-encodes string

urldecode() -- Decodes URL-encoded string


String Encrypt & Decrypt

Encryption

base64_encode -- Encodes data with MIME base64

This encoding is designed to make binary data survive transport through transport layers that are not 8-bit clean, such as mail bodies.

Example :

/* Encrypt */
$str = 'This is an encoded string';
echo base64_encode($str);
/*
Output :
VGhpcyBpcyBhbiBlbmNvZGVkIHN0cmluZw==
*/
?>

Decryption

base64_decode() -- Decodes data encoded with MIME base64

decodes encoded_data and returns the original data or FALSE on failure. The returned data may be binary.

Example :

/* Decrypt */
$str = 'VGhpcyBpcyBhbiBlbmNvZGVkIHN0cmluZw==';
echo base64_decode($str);
/*
Output :
This is an encoded string
*/
?>

nl2br() in php

What is meant by nl2br()?
- nl2br -- Inserts HTML line breaks before all newlines in a string
- Example :
echo nl2br("foo isn't\n bar");
/*output :
foo isn't

bar
*/
?>

strstr() and stristr() in php

What is the functionality of the function strstr and stristr?
- strstr -- Find first occurrence of a string
- Example :
$email = 'user@example.com';
$domain = strstr($email, '@');
echo $domain; // prints @example.com
?>
- stristr -- Case-insensitive strstr()
- Example :
$email = 'USER@EXAMPLE.com';
$domain = stristr($email, 'e');
echo $domain;
// outputs ER@EXAMPLE.com
?>

What is meant by nl2br()?
- nl2br -- Inserts HTML line breaks before all newlines in a string
- Example :
echo nl2br("foo isn't\n bar");
/*output :
foo isn't

bar
*/

get image size in php

How can we get the properties (size, type, width, height) of an image using PHP
image functions?
- getimagesize -- Get the size of an image
- Returns an array with 4 elements.
- Index 0 contains the width of the image in pixels.
- Index 1 contains the height.
- Index 2 is a flag indicating the type of the image: 1 = GIF, 2 = JPG, 3 = PNG, 4 = SWF, 5 = PSD, 6 = BMP, 7 = TIFF(intel byte order), 8 = TIFF(motorola byte order), 9 = JPC, 10 = JP2, 11 = JPX, 12 = JB2, 13 = SWC, 14 = IFF, 15 = WBMP, 16 = XBM. These values correspond to the IMAGETYPE constants that were added in PHP 4.3.
- Index 3 is a text string with the correct height="yyy" width="xxx" string that can be used directly in an IMG tag.
- Example:

list($width, $height, $type, $attr) = getimagesize("reset.jpg");
echo "

Width : ".$width;
echo "
Height : ".$height;
echo "
Type : ".$type;
echo "
Attribute : ".$attr;

/* Output :

Width : 53
Height : 22
Type : 2
Attribute : width="53" height="22"

*/
?>

Iterative statements (loops concepts) in php

Explain about PHP looping?
Looping statements are used in PHP to execute the code for a developer defined number of times.
PHP has these following looping statements they are
- while() loop,
- do while() loop,
- for() loop and
- foreach() loop

/* Example for while() loop */
echo "Example using while() loop to display 1-4 numbers
";
$i=1;
while($i<5){
echo $i." ";
$i++;
}

echo "
Example using do-while() loop to display 1-4 numbers
";
/* Example for do-while() loop */
$i=1;
do {
echo $i." ";
$i++;
}while($i<5);

echo "
Example using for() loop to display 1-4 numbers
";
/* Example for for() loop */
for($i=1;$i<5;$i++){
echo $i." ";
}

echo "
Example using foreach() loop to display 1-4 numbers
";
/* Example for for() loop */
$a = array(1,2,3,4);
foreach($a as $i){
echo $i." ";
}
?>

Difference between sizeof() and count() in php

- count() -- Count elements in a variable
- syntax for count() [int count ( mixed var [, int mode])]
- If the optional mode parameter is set to COUNT_RECURSIVE (or 1), count() will recursively count the array. This is particularly useful for counting all the elements of a multidimensional array. The default value for mode is 0.

- sizeof() function is an alias of count() function
- Example below:
/* Simple Example */
$a = array(1,2,3,4);
echo "
Example #1";
echo "
Count of A array is :".count($a);
echo "
Size of A array is :".sizeof($a);

echo "

Example #2";
$food = array('fruits' => array('orange', 'banana', 'apple'),
'veggie' => array('carrot', 'collard', 'pea'));

/* recursive count */
/* count($food, COUNT_RECURSIVE) equals to count($food, 1) */
echo "
Count of A array is :".count($food, COUNT_RECURSIVE);

echo "
Size of A array is :".sizeof($food, 1);

/* normal count */
/* count($food, COUNT_RECURSIVE) equals to count($food, 1) */
echo "

Example #3";
echo "
Count of A array is :".count($food, 0);
echo "
Size of A array is :".sizeof($food);

echo "

Conclusion :
The sizeof() function is an alias for count().
