[SOLVED] Exploding array

[Thethug]

My objective is to allow the user to input a sentence, explode it by each space, and count how many words are in the sentence.  I then have to output the number of words in the sentence.  Here's what I have so far, but I'm not sure what to do from there. Any ideas would be appreciated.

 

 

<form method='post' action=''>
<input type="text" name="Department1" value = "<?=$_POST["sent"]?>" />  
<input type='Submit' name='Submit' value="Submit" />
</form>

<?


$sentence=$_POST['sent'];


$xplode = explode(",",$sentence);


$count_total = count($sentence);


for ($counter=0; $counter<$count_total; $counter++){

$line = each ($xplode);


echo "$line[key] $line[value] <br />";


}
print_r($array);
?>

You're over complicating things. Do exactly what you said you wanted to do:

$words = $_POST['sent'];
$arr = explode(' ', $words); // Explode by a space
echo count($arr); // Echo out the number.

When I tried it out, it had the textfield and submit button, but it had the number 1 on the bottom.  When I typed a sentence it, it displayed nothing.  Sorry about this dumb question, but I'm brand new to arrays.

 

<form method='post' action=''>
<input type="text" name="Department1" value = "<?=$_POST["sent"]?>" />  
<input type='Submit' name='Submit' value="Submit" />
</form>

<?

$words = $_POST['sent'];
$arr = explode(' ', $words); 
echo count($arr); 
?>

[Alex]

The problem is with your form, not the arrays. Are you expecting them to enter the sentence in the element named "Department1"? If so then you must change $words = $_POST['sent']; to $words = $_POST['Department1']; You don't need to put "<?=$_POST["sent"]?>" either.

<form method='post' action=''>
<input type="text" name="Department1" />  
<input type='Submit' name='Submit' value="Submit" />
</form>

<?

$words = $_POST['Department1'];
$arr = explode(' ', $words); 
echo count($arr); 
?>

 

Ultimately you should also add checking to make sure that the form was actually submitted using isset()

[Thethug]

How would I add checking? It's displaying how many numbers there are in the sentence, which is the second part.  Would adding checking help it to explode the sentence by each space?

[Alex]

Well in your first post you didn't say what else you need it to you. Maybe you made a mistake? You just said it has to output the number of words in sentence. Checking would be simple, just making sure the form was submitted.

 

if(isset($_POST['Submit']))
{
     $words = $_POST['Department1'];
     $arr = explode(' ', $words); 
     echo count($arr);
}

Also, do you (or anyone else) know how to create an array and then implode it into string where the words is separated by commas?

[Alex]

$array = Array('Object1', 'Object2');
echo implode(',', $array); // Object1,Object2

You're over complicating things. Do exactly what you said you wanted to do:

$words = $_POST['sent'];
$arr = explode(' ', $words); // Explode by a space
echo count($arr); // Echo out the number.

 

So are you

I wonder what stupid mistake I did this time.

 

 

<form method='post' action=''>
<input type="text" name="Department1" value = "<?=$_POST["Department1"]?>" />  
<input type='Submit' name='Submit' value="Submit" />
</form>





<?


$array = $_POST['Department1'];

$array = array('Object1', 'Object2');
echo implode(',', $array); // Object1,Object2








?>

<form method='post' action=''>
<input type="text" name="Department1" value = "<?php echo (isset($_POST['Department1'])) ? htmlentities($_POST['Department1']) : ''; ?>" />  
<input type='Submit' name='Submit' value="Submit" />
</form>
<?php
if (isset($_POST['Submit']))
{
   $words = str_word_count($_POST['Department1'], 2);
   $n     = count($words) - 1;

      echo '<p>' . implode(' , ', htmlentities($words, ENT_QUOTES)) . '( ' . number_format($n) . ' words )</p>';
}
?>

It says Warning: htmlentities() expects parameter 1 to be string, array given in /Applications/XAMPP/xamppfiles/htdocs/webalizer/implode.php on line 11

 

Warning: implode() [function.implode]: Invalid arguments passed in /Applications/XAMPP/xamppfiles/htdocs/webalizer/implode.php on line 11

( 4 words ) when I try that.

Sorry. My bad :S
