当PHP中的变量看起来相等时2变量如何不相等？

Question

I have eperienced a very strange issue and I can't get my head around it.

I actually have 2 value which PHP says are NOT equal, when they do equal in my eyes.

I have 2 variables:

$pattern = array('/index/' => 'index');
$uri = $_SERVER['REQUEST_URI'];

$array_key = array_keys($pattern);

echo $array_key[0];
echo $uri;

Actually, when I echo both of these, I get the exact same text in my browser:

/index/

However if I do the following:

if ($array_key[0] == $uri) {
 echo 'Equals';
} else {
 echo 'Not Equals';
}

It ALWAYS gives me that they do NOT equals.

I do not know why is this, but my mind is kinda messed up right now. Can anyone please help me?

Answer 1

try this

if (trim($array_key[0]) == trim($uri)) {
 echo 'Equals';
} else {
 echo 'Not Equals';
}
