Use strlen();

Code: Select all

  <?php
$str = 'abcdef';
echo strlen($str); // 6

$str = ' ab cd ';
echo strlen($str); // 7
?>

The php manual is located here ... its great.... just dont try and print it off like i did..... i gave up after my printer tray was refilled for the 3rd time.


Edit..... i didnt really try and print it off... sheesh... do i look dumb :P

hello

can anybody give me another sample script on password must be more than 3 char.. im struggling here... plss

Code: Select all

<?php
$str = 'abcdef';
echo strlen($str); // 6

$str = ' ab cd ';
echo strlen($str); // 7
?>

The above is all you need..... or do you want me to write the entire script for you?

Let me talk you through the logic.... strlen() returns a numerical value equal to the length of the string passed into it

so.... pass your password into strlen() then use an if else statement to check it is more than 3 chars in length ....

Does that make things clearer?



edit:

just o make things really simple (and cos im a nice person )

Code: Select all

<?php
$pass = $_POST['pass'];

$pass_len = strlen($pass);

if ($pass_len < 3) {
echo "YOUR PASSWORD MUST BE LONGER THAN 3 CHARS!!";
}
else {
echo "Thankyou, your password has been accepted";
}
?>

Thats about as simple as i can make it..... basically all you need to do is change the echo statements to whatever procedural code you want in each outcoe and your done.

But seriously.... go and browse the php documentation... its a life saver
