Cut a string into pieces (PHP! ;-) )

You could use substr while looping up to the length of the string and using array_push to build your $string_array.

Oh, yeah, I’m not so good with loops too.
Would you be so nice to write it for me? Thanks.

Come to think of it you might be able to use:

explode(””, $example_string);

iirc, explode is what you want.

Of course! That I didn’t think of that. Thanks!

Now I have this:

$email_text = randomcode(1,8,false); //is a function to generate a random code
$email = explode(””, $email_text);
echo ($email[0].$email[1]. ”<del>” .$email[2].$email[3].$email[4]. ”*” .$email[5].$email[6]. ”</del>” .$email[7]);

But it gives me the random code, and then <del>*</del> after that, not in between the characters. What am I doing wrong?

Stupid textile. <del> is an -.

This is the page: http://ole.daveyyzermans.nl/images/captcha.php. I’m trying to make a kind-of captcha.

Then you may need to loop. I don’t have PHP installed and I’m a bit rusty but I’ll give it a try:

$length = strlen($email_text);
$email = array();
for ($c = 0; $c < $length; $c++) {
array_push($email, substr($email_text, $c, 1));
}

On a side note, they really need block code formatting here on Fluther :)

Yep, it works. Thanks again.

Speaking of captchas, you might want to check out http://recaptcha.net/.

I decided to use this not so very secure captcha, because it’s not an important form, so…
Thanks anyway.

You don’t want to use explode() but str_split().

$stringArray = str_split($string);
