Je veux afficher la valeur du bouton radio de MySQL en PHP

Cela devrait fonctionner et regarde un petit Néater: xxx

Vous êtes presque là-bas, le seul problème est l'espace entre les attributs entre «valeur» et «coché». Votre code sera traduit dans:

<div class="form-group">
    <label>Gender</label>
    <label class="radio-inline">
        <input type="radio" name="gender" value="male" <?=$row["gender"] == 'male' ? 'checked' : ''?>/>
        Male
    </label>
    <label class="radio-inline">
        <input type="radio"  name="gender" value="female" <?=$row["gender"] == 'female' ? 'checked' : ''?>/>
        Female
    </label>
    <label class="radio-inline">
        <input type="radio" value="others" name="gender" <?=$row["gender"] == 'others' ? 'checked' : ''?>/>
        Others
    </label>
</div>

 <h2>CRUD OPERATION</h2>
                <?php
                 $id=$_GET['id'];
                $query_update = "select * from crudtable where id=$id";
                $res_update = mysqli_query($conn, $query_update);
