I have a 5 letter string eg: etd00 and AA001

 

there is any way in PHP to check first 2 letters are capital or not?

<?php

$string1 = 'etd000';
$string2 = 'AA001';

function check( $string ) {
$a = ord($string[0]);
$b = ord($string[1]);
return $a > 64 && $a < 91 && $b > 64 && $b < 91;
}

var_dump(check($string1));
var_dump(check($string2));

function check_alternate($string) {
return (bool) preg_match('/^[A-Z]{2}/', $string);
}

var_dump(check_alternate($string1));
var_dump(check_alternate($string2));

?>

<?php

$string ="Anything you want here"; //your string here

$array=str_split($string);

If(ord($array[0])>=65 AND ord($array[0])<=90)
echo "First letter is Capital";

If(ord($array[1])>=65 AND ord($array[1])<=90)
echo "Second letter is Capital";


?>

Rather than deal with ASCII numbers, how about a plain and simple

$string = "etd00";

$condition = (/* strlen($string) >= 2 && */ $string[0] >= 'A' && $string[0] = 'A' && $string[1]

And why not just use a comparison using strtoupper()?

 

function checkFirstTwo($string)
{
    $firstTwo = substr($string, 0, 2);
    return ($firstTwo == strtoupper($firstTwo));
}

And yet another way . . .

 

if( ctype_upper(substr($string, 0, 2)) ) {

if( ctype_upper(substr($string, 0, 2)) ) {

 

Totally forgot about ctype_upper() - good call.
