I have an HTML form with a comment box textarea. I want to be able to count how many words were input (which I have done with str_word_count then I want to be able to tell the user how many times each word appeared in the string. I can print the values like this Array ( [I] => 1 [like] => 1 [comments] => 1 ) but how would I output into a 2 column table where it shows the word and the count?
Thanks for any help!
Form Code:
<html>
<head>
<title>PHP Form</title>
</head>
<body>
<form name="newForm" method="post" action="formProcess.php">UserName:
<input type="text" name="userName" size="15" maxlength="15">
<br>Password:
<input type="password" name="pass1" size="15">
<br>Confirm Password:
<input type="password" name="pass2" size="15">
<br>
<p>I agree to the terms and conditions.
<br>
<input type="radio" name="terms" value="yes">Yes
<input type="radio" name="terms" value="no">No
<p>Enter comments here:
<br>
<textarea name="comments" rows="6" cols="50" wrap="physical"></textarea>
<p>
<input type="submit" name="submitForm">
<input type="reset" name="resetForm">
</p>
</form>
</body>
</html>
PHP:
<?php
$userName = $_POST[userName];
$pass1 = $_POST[pass1];
$pass2 = $_POST[pass2];
$terms = $_POST[terms];
$comments = $_POST[comments];
echo "Username: $userName<br />";
echo "Terms Agreed to? $terms<br />";
echo "Your comments: $comments<br />";
$count = str_word_count($_POST['comments']);
print_r( array_count_values(str_word_count($comments, 1)) );
echo "Total words in comment box: $count<br />";
function validatePassword($pass1,$pass2) {
if($pass1 === $pass2)
{
$msg = "Password confirmed!";
}
else
{
$msg = "Passwords do not match!";
}
return $msg;
}
echo validatePassword($pass1, $pass2);
?>
The code you posted in the comments is ok, but it considers words written with different casing as different words (like "Comments" and "comments"). So don't forget to use strtolower:
<?php
$comments = "Comments? I like comments.";
$commentsArray = array_count_values(str_word_count(strtolower($comments), 1));
echo "<p>How many words were input: " . count($commentsArray) . "</p>";
?>
<table>
<tr>
<th>Word</th>
<th>Count</th>
</tr>
<?php foreach($commentsArray as $word=>$count): ?>
<tr>
<td><?php echo $word; ?></td>
<td><?php echo $count; ?></td>
</tr>
<?php endforeach; ?>
</table>
This script echoes:
How many words were input: 3
Word Count
comments 2
i 1
like 1
to show in two column, just loop through the array. and you'll get your result
<?php
$string = "Hello, still2blue. This is your string. This string is repeated";
$words_list = str_word_count($string, 1); // this returns the array of words
$results = array_count_values($words_list);
foreach($results as $word => $count){
echo sprintf("%-10s %2d", $word, $count) . PHP_EOL;
}
