Loops are used to run the same lines of code for multiple times. If we want to execute same code multiple times then we can put it into a loop block to avoid code repetition. Loop structure includes three sections. These are, Initialization  – To initialize the first iteration index of the loop. Conditional execution – For each iteration, it checks whether the specified condition is satisfied. If so, then only the code will be executed. Incrementation/decrementation – After processing each iteration, the loop index should be incremented or decremented to process next iteration. This will be continued till the loop condition is satisfied. PHP supports four types of loop statements. These are,  while ,  do…while ,  for and  foreach . In this tutorial, we are going to see about each of these types of PHP loop statements with an example. I have added a demo with  nested for loop  to print star triangle. view demo while The following example code shows a  while  loop with i

In PHP there are various methods to print data. PHP provides more functions and language constructs for printing various data types. These functions are varied on the data format printed on the browser using them. For example, the print() and echo() statements prints string data, whereas, the  print_r()  is used to print compound datatype like arrays  or objects. In this tutorial, we are going to see some of the PHP functions that are used to create print statements. I have added the example code for each function. PHP Functions used for Printing Data print()  – The  print()  is used to create PHP print statement to print given data to the browser. It accepts single data and prints it on the browser. It is a PHP language construct and not a function. So, we can use ‘print’ without parenthesis for creating a print statement. The code shows an example for using  print  with and without parenthesis where both will print same data. print "Apple" ; //(or) print ( &

PHP delimiters are nothing but the open close tags to enclose PHP script. PHP code can be parsed if and only if it is enclosed with these delimiters. There are various set of delimiters to recognize PHP code. These are as listed below. <?php … ?>  – It is most probably used delimiters and also preferable, since, PHP code enclosed with in <?php .. ?> could be recognized with other PHP servers independent of the tag related configuration directives. <script language=”php”></script>  – This will also work anywhere, like <?php … ?>. <? … ?>  – This is called as PHP short tags which will work based on the value set with  short_open_tag  directive of PHP configuration file. <?=..;?>  – This is also short form of denoting PHP code, but used as an alternative representation of PHP print statement. <% … %>  or  <%=;%>    – This is the delimiters for writing Active Server Pages(ASP) code. But it will be used for PHP code if and only

After installing xampp  you are ready to start with php. This is our first blog through which you can learn php.  So let me start with the Hello World program in PHP. Following script displays the sentence “Hello, World!” in the browser. It is a simple and straight forward code. There are two basic ways of doing this hello world print and they are using ‘echo’ or ‘print’.  The difference between using ‘echo’ and ‘print’ is, the echo statement just prints the arguments passed to it and does not return any value. But the ‘print’ statement prints the argument as well as returns a value of 1. Since it returns a value, ‘print’ statement can be used in expressions. the echo statement can take multiple parameters and print statement takes only one parameter. Example Hello World Code using Echo <? php echo "Hello, World!" ; ?> Example Hello World Code using Print <? php print "Hello, World!" ; ?> In this context of printing ‘Hello,
