entity encoding - Why I see Α' Γ instead of Α' Γ ?

The reason you are seeing Α and Γ instead of the actual Greek letters Α and Γ is because they are being encoded as HTML entities. These entities are used to represent special characters in HTML, but they can also be decoded back into their original characters.

To handle them as equal in PHP, you can use the html_entity_decode function to convert the HTML entities back into their corresponding characters. Here is an example:


Αντιγραφή
$str1 = "Α";
$str2 = "Γ";

$char1 = html_entity_decode($str1, ENT_COMPAT, 'UTF-8');
$char2 = html_entity_decode($str2, ENT_COMPAT, 'UTF-8');

if($char1 == $char2){
    echo "The characters are equal: " . $char1 . " " . $char2;
} else {
    echo "The characters are not equal: " . $char1 . " " . $char2;
}
This code will decode the HTML entities Α and Γ and compare the resulting characters. If they are equal, it will output a message saying so. Otherwise, it will indicate that they are not equal.
