Compare data

[tyra]

Hi guys!

 

Text input file looks like this: Code:

<?php 

if($_POST['text'] != null){ 
echo 'Entered text: '.$_POST['text']; 
  }else{ 
echo '<form action="'.$_SERVER['PHP_SELF'].'" method="post">Enter text:<input type="text" name="text"><input type="submit" value="Submit"></form>'; 
    } 
?>

 

 

But how to double it and then set to compare eachothers submitted data ?

 

The goal is to have 2 textareas. Area1, area2 where text entered to area2 is compared with text from area1 and text entered to area1 is compared with text from area2. Differences will be marked bold after submitting.

exaple:

before submiting:

textarea1: NASA

textarea2: NASCAR

after submiting:

textarea1: NASA

textarea2: NASCAR

You could split each input into an array of each letter.

Then compare each letter with it's corresponding letter. If they match, add the letter to a new array, if they don't add it to the new array along with a font-weight tag.

 

Then echo both arrays.
