将三元运算符分解为if语句？

Question

我有这样的代码：

$get_options = isset($options['big_heading']) ? ($options['big_heading']) : '' ;但我很难将其视为三元运算符，那么如何将其分解为if语句？对不起我的noobish问题...... 谢谢!!

Answer 1

您的代码等于：

if(isset( $options['big_heading'])){
    $get_options = $options['big_heading'];
} else {
    $get_options = '';
}

此语法总是如下：$foo = (condition) ? if_its_true : if_its_not_true ;

Answer 2

这与

相同

$get_options = isset( $options['big_heading']) ? ($options['big_heading']) : '' ;

此

if(isset( $options['big_heading'])) {
    $get_options = $options['big_heading'];
} else {
    $get_options = '';
}

Answer 3

if(isset( $options['big_heading'])) {
  $get_options = $options['big_heading'];
} else {
  $get_options = '';
}

Answer 4

$get_options = "";

if(isset( $options['big_heading']))
{
   $get_options = $options['big_heading']
}

Answer 5

$get_options =  '' ;
if (isset( $options['big_heading'])) {
 $get_options = $options['big_heading'];
}

Answer 6

你去......

if (isset($options['big_heading'])){
    $get_options = $options['big_heading'];
else{
    $get_options = '';
}
