Another PHP Question =)

I've written my very first PHP application but I'm stuck on one thing!

This is what I've got

<?php
$quote = $_POST['quote'];
?>

PHP:

			<form action="index.php" method="post">
				<textarea rows="10" cols="30" name="quote" id="quote"></textarea>
				<input type="submit" value="Submit">
			</form>

HTML:

Now, say someone throws this into the form:

I'd need it to strip the spaces out, and between the letters in the alphabet spit it out like this

<a>hello</a><b>how</b><c>are</c>

BUT the letters are to be random not in order so it can be

<b>hello</b><z>how</z><c>are</c>

etc.

Is this possible?

 

Hello,
Take a look around this functions

http://ar2.php.net/manual/es/function.explode.php

Maybe this can help you.

Best,
Jakomo

 

Hmm, the only thing I foud relevant is this:

<?php
function between($beg, $end, $str) {
$a = explode($beg, $str, 2);
$b = explode($end, $a[1]);
return $beg . $b[0] . $end;
}

echo between('<a>', '</a>', 'fsdfsdfsd<a>fsdfsd<a><a></a>sdfsdfsdf')
//<a>fsdfsd<a><a></a>
?>

PHP:

But I don't understan how to get the random <b> </b> <f></f> etc wrapped around each word randomly.

 

I terribly fail to see what this would be useful for, but I guess it has its purpose. This works:

function wrap_word($word)
{
	$letter = chr(rand(97, 122));
	return "<{$letter}>{$word}</{$letter}>";
}

$string = 'Hello how are you today';

$string = preg_replace('/\s*([\w]+)\s*/e', 'wrap_word("$1")', $string);

echo $string;

PHP:

 

Hello,

You can do something like this

$tag[1]="<b>"
$tag[2]="<f>"
$tag[3]="<a>"

count how many words you have in the string with count
Example:
Hello happy friends

You here have 3 words

when make a loop of this three words

while (1 to count(string))
{
Then use the rand function to get a randon number..
http://ar2.php.net/rand
echo tag[rand]. WORLD STRING (ie: Hello). "/".tag[rand];
}


Well this is the idea, I hope you can understand it.

It's for a dynamic text replacement script im making, so each word is spit out in its own font/color.

 

Thanks nico_swd, you've come through again!

Cheers!

 

Here another way to do it, 'cause I was bored.

$string = ' Hello how are you today';

$string = preg_replace_callback(
	'/\s*([^\s]+)\s*/',
	create_function(
		'$word',
		'$letter = chr(rand(97, 122));
		 return "<{$letter}>{$word[1]}</{$letter}>";'
	),
	$string
);

echo $string;

PHP:

 

Is there anyway you can have it so it keeps the "," " ' ", "!" etc in the submitted string

 

The second version should do that. Or just use the RegEx pattern from the second in the first version.
