Question

How can i make this comparison return true?

$var1="á";
$var2="á";

if ($var1==$var2) {
    return true;
}

The funny thing is that i dont know if the html entity is in var1 or in var2, so i need to put the same function in both sides of the comparison.

I tried with html_entity_decode, htmlentities and a combination of both.

Any ideas?

Thanks!

Can’t you just use an or comparison in your if statement? If either $var1 or $var2 is a HTML entity, it should return true nicely.

<?php 
    $var1="á";
    $var2="&aacute;";

    if (html_entity_decode($var1)==$var2 || html_entity_decode($var2)==$var1) {
        return true;
    }
?>

If you might have them in boht or either field, you could add in a third comparison like this:

<?php 
    $var1="á";
    $var2="&aacute;";

    if ($var1==$var2 || html_entity_decode($var1)==$var2 || html_entity_decode($var2)==$var1) {
        return true;
    }
?>
