your recieve the string ie

the man well

 

so

$theSring = "the man well"

then your break it up into an array ie

$theArray = explode(" ",$theString); // the " " means space delimitor

 

so

<?php
$theArray = explode(" ",$_POST['theText']);
print_r($theArray);

?>

 

for the 2nd one, well you probably best storing the posted data, in a file or Database, then when the other client machines refesh it displays that data stored!

1. Simply do:

$textarea_text = $_POST['textarea_name'];
$textarea_text_array = explode("\n", $textarea_txt);

echo '<pre>' . print_r($textare_text_array, true) . '</pre>';

2. That will be done in javascript.

Ok thank you all ppl

and what the name of his script? or you can give me that script i well be grateful to you

(?)

[wildteen88]

All it'll take is one line of javascript, something like:

<textarea onkeyup="document.textarea2.value=this.value"></textarea>

Create another textarea and give it an id of textarea2, eg:

<textarea id="textarea2"></textarea>

 

It may not work, it is only for an example code. However do test it.

It is better to use an array then separate variables. I'm asumming you're using my code

 

So if someone entered

"one

two

three"

 

into the text box (Minus the quotes). Then to get the first word you'd use $textarea_text_array[0], to get the second you'd use $textarea_text_array[1] and finally $textarea_text_array[2] to get the last. Arrays start at zeros. I know when using arrays for the first time it seems confusing however arrays can very helpful when used in the correct way.

 

My code is just an example, you can change the variable $textarea_text_array to shorter one instead, by simple changing, this line:

$textarea_text_array = explode("\n", $textarea_txt);

 

to:

$words = explode("\n", $textarea_txt);

Then use $words[0],  $words[1], $words[2] to retrieve the words.

 

To understand arrays further I encourage you to have a read of the manual on arrays.

[ansarka]

function split_array($string,$splitter)

{

    $textarea_text_array = explode($splitter, $string);

    return $textarea_text_array;

}

 

 

you can call this function like

 

split_array('/', $string);

split_array('/n', $string);
