How to use while loop to realize solid diamond shape in php

PHP is a very popular server-side programming language, and its versatility and adaptability make it a popular choice among developers. While it's given a decent amount of space, it has a lot of flexibility in terms of the skills it performs. One of the most useful features is the while loop. In this article, we will explore how to implement a solid diamond using PHP’s while loop.

Normally, solid diamonds are constructed through nested loops. In the while loop in PHP, we will use two loops - inner loop and outer loop. The outermost loop is used to cycle through the number of rows, while the other loops are used to create equally spaced gaps and asterisks in each row.

Here is the code we will use:

<?php
 
    $rows = 9;
    $i = 0;
    $j = 0;
 
    while($i < $rows)
    {
        $j = 0;
         
        while($j < ($rows - $i))
        {
            echo " ";
            $j++;
        }
         
        $j = 0;
         
        while($j < (2 * $i - 1))
        {
            echo "*";
            $j++;
        }
         
        echo "\n";
        $i++;
    }
 
    $i = $rows-2;
     
    while($i >= 0)
    {
        $j = 0;
         
        while($j < ($rows - $i))
        {
            echo " ";
            $j++;
        }
         
        $j = 0;
         
        while($j < (2 * $i - 1))
        {
            echo "*";
            $j++;
        }
         
        echo "\n";
        $i--;
    }
 
?>

In the above code, we have defined a $rows variable to specify the total number of rows and $i and $j variables to control the columns and OK. We will use two while loops, the first while loop is used to loop through each line, while the second while loop is used to create a set of spaces and asterisks in each line.

The first loop's job is to create a set of spaces at the beginning of each line to create a solid diamond shape when centered. When $i loops through a complete line, the results for that line are output to the screen. When all rows are complete, we loop back in the opposite direction and repeat the same operation as before, but this time, we decrement the $row variable by one.

One thing to note is to leave a space between each space or asterik symbol "*" to make the diamond easier to see. To remove these extra spaces, you can use $j and $i variables for calculation and processing.

In the above code, we use three while loops, but their operations are very similar. Within each stage of the loop, we use separate loop control variables to control each loop.

In this example we use some nested loops and basic arithmetic to count spaces and asterisks in each line. Using these tips we can approach every detail in an independent and fearless way so that we can create complex patterns quickly and easily.

Overall, PHP’s while loop is very powerful and very effective in helping you create patterns like solid diamonds. With just a little time and effort, you can easily create unique and interesting shapes and patterns.
