CodeIgniter 3：if语句在Php中不起作用的多个条件

Question

I'm new with CodeIgniter. I have an if/if else statement in my view file and the codition after || is not working

Here's a code from my view

<?php if (($destination["site"]!="block_view/profile/profile")||($destination["site"]!="block_view/profile/slips")){
?>


<section id="profilephp-header" style="background-image: url(<?php echo base_url('assets/img/parallax/header-profile.jpg'); ?>);" class="parallax">
    <div class="overlay">
        <div class="container">
            <div class="row">
                <div class="sec-title text-center wow animated fadeInDown">
                    <img src="<?php echo base_url('assets/img/parallax/profile-text.png'); ?>" alt="">
                </div>
            </div>
        </div>
    </div>
</section>
<?php 
}else if(($destination["site"]=="block_view/profile/profile")||($destination["site"]=="block_view/profile/slips")){?>
    <section id="profilephp-header2" style="background-image: url(<?php echo base_url('assets/img/parallax/header-profile.jpg'); ?>);" class="parallax">
        <div class="overlay">

        </div>
    </section>
<?php
}?>

It seems like the if statement is only accepting one condition. All the conditions in my view files is like this.

$destination['site'] has one value, but in your first if-statement, you're checking if it's either not equal to one thing, or it's not equal to another thing. That'll always be true!

It looks like you were intending to show that section if the destination site was neither of those, so you could rewrite it as this:

<?php if (!in_array($destination['site'], ['block_view/profile/profile', 'block_view/profile/slips'])): ?>
<section id="profilephp-header" style="background-image: url(<?php echo base_url('assets/img/parallax/header-profile.jpg'); ?>);" class="parallax">
    <div class="overlay">
        <div class="container">
            <div class="row">
                <div class="sec-title text-center wow animated fadeInDown">
                    <img src="<?php echo base_url('assets/img/parallax/profile-text.png'); ?>" alt="">
                </div>
            </div>
        </div>
    </div>
</section>
<?php else: ?>
    <section id="profilephp-header2" style="background-image: url(<?php echo base_url('assets/img/parallax/header-profile.jpg'); ?>);" class="parallax">
        <div class="overlay">

        </div>
    </section>
<?php endif; ?>
