check first 2 digits

[matleeds]

Hi,

 

I'd like to know what the most efficient code is for checking the first 2 digits of a string.

 

eg a strings first 2 digits must  equal '07'

 

thanks,

Try that

$num = '07654';
$check = substr($num, 0, 2);
if($check == '07')
    echo 'OK';
else
    echo 'BAD';

thanks. how would one use that  if ? : statement in this context

The ternary operator ?

Do you mean it ?

$num = '07654';
$check = substr($num, 0, 2);
echo $check == '07' ? 'OK' : 'BAD';
