An object is a singletonif the application can include one and only one of that object at a time. for($j=1; $j<=$i; $j++) //loop to print spaces In this example, the value I for loop is iterated 5 times, as the number of rows in the star pattern is 5. The front controller pattern is where you have a single entrance point for your web application (e.g. We use for loop to print these patterns. Now the value of i is incremented by 1, which means the value is 2 and again the j for loop will loop 5 times and print the 5 stars. } The singleton pattern covers this need. //example to demonstrate star pattern-5 For example, the connection to a database through the database handle is exclusive. Design Patterns in PHP to Solve real-life Software Problems. Inside the for loop is, again a for loop for columns, where the variable j is initialized to 0 and this loop will print stars(*) in the first row, and will loop till the condition $j< 5 is satisfied. Next for the value of 2, the j loop will print 4 stars, for the next value 3, the j loop will print 3 times and so on. } Design Patterns in PHP. echo '
