Hi

Can someone please explain why it prints 2?

Code:

<?php
if ('EMAIL' == 'EMAIL'){
print "1";
}else{
print "2";
}
?>

PFA code snippet.

Thanks

There are special characters at the beginning of the first EMAIL string. When I copied/pasted the code above, I get 2. When I type everything out manually from scratch, I get 1. If I paste the code into a raw text field, I get what visually appears to be a tabbed space. Something like so:

Code:

if ('	EMAIL' == 'EMAIL'){

So let's just split the strings by character and see what we get.

PHP Code:


			
$chars = str_split( 'EMAIL' );
print_r( $chars );

$chars = array_map( 'ord', $chars );
print_r( $chars );

First EMAIL string:

Code:

Array
(
    [0] => ï
    [1] => »
    [2] => ¿
    [3] => E
    [4] => M
    [5] => A
    [6] => I
    [7] => L
)
Array
(
    [0] => 239
    [1] => 187
    [2] => 191
    [3] => 69
    [4] => 77
    [5] => 65
    [6] => 73
    [7] => 76
)

Second EMAIL string:

Code:

Array
(
    [3] => E
    [4] => M
    [5] => A
    [6] => I
    [7] => L
)
Array
(
    [3] => 69
    [4] => 77
    [5] => 65
    [6] => 73
    [7] => 76
)

Yeppers, the first email has utf-8 BOM in it:

Code:

� = 239
� = 187
� = 191
E = 69
M = 77
A = 65
I = 73
L = 76

E = 69
M = 77
A = 65
I = 73
L = 76

Haha, sorry... I had a simple answer, then got curious and did a bit more testing.
