Relevant Source code
The following are the requirements for this tutorial:
- XAMPP
- Text editor (VS Code, Sublime, Brackets), download and install a text editor of your choice
Line 19-25 – this is the scope of the HTML Form, we all know that the purpose of the form is to capture the user input. In this case, we want to capture two strings and let PHP process the merging of two strings into one.
Line 26-33 – this is the scope of our PHP script. It starts at line 26 and ends at line 33.
Line 28 – this is where we declare our first variable $str1. The variable will hold the value entered by the user in the first text box.
Line 29 – this is where we declare our second variable $str2. The variable will hold the value entered by the user in the second text box.
Line 30 – this is where we will merge the two strings using the concatenation operator. We will now declare a new variable $new_str after we have merge $str1 and $str2.
Line 31 – this line is responsible for displaying the value of $new_str variable that merges the two strings entered by the user in the text boxes.
<form method="post">
<label>String 1</label>
<input type="text" name="str1" class="form-control"><br>
<label>String 2</label>
<input type="text" name="str2" class="form-control"><br>
<input type="submit" name="submit" class="btn btn-primary" value="Merge String">
</form><br>
<?php
if($_POST){
$str1 = $_POST['str1'];
$str2 = $_POST['str2'];
$new_str = $str1.' '.$str2;
echo "<h4>Merge String is: ".$new_str."</h4>";
}
?>
