Re: Coloring text

Surely this is a question to do with html then.

Re: Coloring text

I think you did not understand me, I explain:
I wrote a chat program , I want when a user sends a message the message appears with mixed colors... the color of the first letter=green , the 2nd letter=red , the 3rd letter=blue and start over the 4th letter=green ,the 5th letter=red the 6th letter=blue and start over the 7th letter=green, 8th letter=red , 9th letter=blue .... until the message's end.

Re: Coloring text

Honey you do realise the colour is rendered in html? The clever bit, i.e. first letter green second letter red, is done by writing code. Try it.

Re: Coloring text

nevermind about the customizing. i made it into a function. lets say you have words contained in the variable $string, all you would have to do is call the function "color()" with the string that needs to be colored inside the parathesis ex. "color($string)" and the colored text will echoed onto the page.

Heres the color function code:

PHP Syntax (Toggle Plain Text)
<?php
function color($str) {
$i = 0;
while ($i < strlen($str)) {
$letters[] = substr($str, $i, 1);
$i++;
}
$colors = array(0 => '<font color="green">',1 => '<font color="red">',2 => '<font color="blue">');
$i = 0;
$c = 0;
while ($i < count($letters)) {
if ($c == 3) {
$c = 0;
}
echo $colors[$c] . $letters[$i] . '</font>';
$i++;
$c++;
}
}
?>
<?php
function color($str) {
$i = 0;
while ($i < strlen($str)) {
$letters[] = substr($str, $i, 1);
$i++;
}
$colors = array(0 => '<font color="green">',1 => '<font color="red">',2 => '<font color="blue">');
$i = 0;
$c = 0;
while ($i < count($letters)) {
if ($c == 3) {
$c = 0;
}
echo $colors[$c] . $letters[$i] . '</font>';
$i++;
$c++;
}
}
?>
