trying to use a php variable inside a form without much success

its just a simple check to see if a questions on the form should be asked or not

here is what I have been trying:

<?php if ($asksex = 1): ?>
Gender <br>
  <input type="radio" name="sex" value="male" checked> Male<br>
  <input type="radio" name="sex" value="female"> Female
    
    
<?php else : ?>
    
<?php endif; ?>

<?php if ($asknews = 1): ?>
    Subscribe me to your news letter
  <input type="checkbox" name="sex" value="yes" checked= true>
    
    
    <?php else : ?>
    
<?php endif; ?>

what am i doing wrong?

You're using an assignment operator, not a comparison operator. Try -

<?php if ($asksex == 0): ?>
Gender <br>
  <input type="radio" name="sex" value="male" checked> Male<br>
  <input type="radio" name="sex" value="female"> Female

<?php else : ?>

<?php endif; ?>

<?php if ($asknews == 0): ?>
    Subscribe me to your news letter
  <input type="checkbox" name="sex" value="yes" checked= true>

    <?php else : ?>

<?php endif; ?>
