我正在尝试回显特定数据的性别的当前值，并在用户想要时编辑性别。我怎么能用这段代码呢？
这是我的代码：
echo "Gender: <label class=\"radio-inline\"><input type=\"radio\" name=\"gender\" value=\"Male\" > Male</label>
<label class=\"radio-inline\"><input type=\"radio\" name=\"gender\" value=\"Female\"> Female</label><br/>";
以下是我如何获取数据库中所有信息的完整代码：
<?php
while(mysqli_stmt_fetch($stmt1)) {
echo "First Name: <input type=\"text\" style=\"border: none; border-color: transparent;\" value=\"$first_name\"><br/>";
echo "Middle Name: <input type=\"text\" style=\"border: none; border-color: transparent;\" value=\"$middle_name\"><br/>";
echo "Last Name: <input type=\"text\" style=\"border: none; border-color: transparent;\" value=\"$last_name\"><br/>";
echo "Age: <input type=\"text\" style=\"border: none; border-color: transparent;\" value=\"$age\"><br/>";

使用单选按钮中的if条件选择存储的值，如
$gender = 'Female';
echo "Gender: <label class=\"radio-inline\">
<input type=\"radio\" name=\"gender\" value=\"Male\" ";
if(isset($gender) && $gender == 'Male') { echo 'checked';}
echo " > Male</label>
<label class=\"radio-inline\">
<input type=\"radio\" name=\"gender\" value=\"Female\" ";
if(isset($gender) && $gender == 'Female') { echo 'checked';}
echo "> Female</label><br/>";

假设您在数据库表中存储了1个男性和0个女性，那么从数据库中获取的代码可以实现为：
<input type="radio" name="gender" <?php echo $row['gender'] === '1' ?'checked="checked"':'';?>/> Male
<input type="radio" name="gender" <?php echo $row['gender'] === '0' ?'checked="checked"':'';?>/> Female
多数民众赞成。如果男性存储在数据库中，那么将检查第一个，否则将检查第二个。

尝试这样的事情，使用单引号作为echo，并使用双引号作为值，这很容易做到。
<?php
$gender = 'Male';
echo 'Gender: <label class="radio-inline">
<input type="radio" name="gender" value="Male"';
if(isset($gender) && $gender == 'Male') { echo 'checked="checked"'; }
echo ' > Male</label>
<label class="radio-inline">
<input type="radio" name="gender" value="Female" ';
if(isset($gender) && $gender == 'Female') { echo 'checked="checked"'; }
echo '> Female</label><br/>';
?>
