Basic for Function on PHP

By rahulitjec - September 13, 2014

Function: Function are a set of bloch, which are defined for calling a set of code again and again. There are two way to calling a function in PHP: Directly calling a Function. Function called by a object of a class and defined within a class. They are Important as some of the code, we have to use different location on a site. So a good way is to define in a File i.e. "functions.php" and include it to top of the position. ############################ PHP Code ############################ Program 01: Normal Function just running the code within it <?php // Normal Function just running the code within it // function definition function callme($a,$b) { // echo " Sum of the ".$a." and ".$b.

Type of the Variable

By rahulitjec - September 08, 2014

Here we will understand, How we can know the type of the variable. As PHP automatic set the type to the variable as we defined it, But sometime it is neccessary to check the type of the variable. Suppose you have a condition, that it there is more then 10 Items in store, you will add them all for calculation of the total payment, but when the item is only one, there is no need to adding them, as the total cost will be cost of the item. So you can do by checking the variable type of the variable m If it is array then we will add them all, if this is only a string or Integer, and it is the final cost. Example you have an Variable $value. if it is array, we will use array function to check as follow: <?php $totalcost = 0; if( is_array ($value) ) { foreach ( $value as $single ) { $totalcost = $totalcost + $value;

Loop in PHP - For Loop

By rahulitjec - September 08, 2014

So we are going to understand the for loop. As you know the loop is a re-execute of a block code for the some condition to be true. For example, I will keep waking till I reached the temple. Here Temple is a condition and walk is the block of code to be executed. The structure of the for loop as follow: for ( {initial value for the loop} ; { contion to be check } ; { initial value to be changed } ) { } #################################### PHP Code #################################### <html> <head> <title>Loop Example- for</title> </head> <body> <h3> Example 1 </h3> <?php for ( $i = 1 ; $i < 5 ; $i++ ) { echo " The Value ot the Intiator : " . $i ; } ?> <hr/> <h3> Example 2 </h3> <?php for ( $j = 5 ; $j > 1 ; $j-- ) { echo

Loop in PHP - while loop

By rahulitjec - September 07, 2014

Logical Expression in PHP

By rahulitjec - September 06, 2014

Today, we will talk about logical expression in PHP. Syntax of the Logical expression are same as the other Programming languages i.e. C and java. Syntax: if Condition: if(condition) run this if else Condition: if(condition) run this else run this nested if else Condition: if(condition) run this else if run this else run this ############################ PHP Code ############################ <?php $a = 4; $b = 5; // if condition if( $a > $b ) // if no curly braces is used, then only next line will be executed echo " a is greater then b "; echo " this will not depend on the condition "; echo " <hr/> "; if( $a < $b ) echo " a is less then b "; echo " this will not depend on the condition "; echo " <hr/> ";

What is MD5 ?

By rahulitjec - September 05, 2014

MD5 stands for 'Message Digest algorithm 5'. MD5 algorithm is used as a cryptographic hash function or a file fingerprint. Often used to encrypt password in databse, MD5 can also generate a fingerprint file to ensure that a file is the same after a transfer for example. A MD5 hash is composed of 32 hexadecimal characters. Enter a word in the MD5 encrypter form above to know the corresponding MD5 hash. What is a MD5 hash? MD5 (Message Digest algorithm, 5th version) is an algorithm which converts a given sequence of characters into another unique sequence of characters, with a fixed length, called "hash". For instance, the MD5 hash of the word "admin" is "21232f297a57a5a743894a0e4a801fc3". These hashes are mostly used to validate file integrity, to encrypt sensitive data (like passwords), and to generate unique identifiers. Is it secure? MD5 hashes are theoretically impossible to reverse directly, ie, it is not possible to retrieve the or

Moving to a New Server If you are moving WordPress from one server to another, begin by backing up your WordPress directory, images, plugins, and other files on your site as well as the database.
