Step by Step solution about How to resolve the algorithm Tokenize a string step by step in the PHP programming language

The PHP code you provided is using the implode() and explode() functions to modify a string. Here's how it works:

1. Explode The explode() function takes two arguments:

• The delimiter (in this case, a comma ,)
• The string to be split

In the code, explode() is used to split the string $str into an array using the comma as a separator. The resulting array will contain the individual words from the string:

$arr = explode(',', $str);

// $arr will now contain ['Hello', 'How', 'Are', 'You', 'Today']

2. Implode The implode() function does the opposite of explode(). It takes two arguments:

• The glue (in this case, a period .)
• The array to be joined

In the code, implode() is used to join the elements of the array $arr into a single string using the period as a separator:

$newStr = implode('.', $arr);

// $newStr will now contain 'Hello.How.Are.You.Today'

3. Output The echo statement is used to output the value of $newStr, which is the modified string with periods separating the words:

Hello.How.Are.You.Today

Therefore, the code takes the input string $str, splits it into words using explode(), and then joins the words back together into a new string with periods as separators using implode().

<?php
$str = 'Hello,How,Are,You,Today';
echo implode('.', explode(',', $str));
?>
