1. 创建一个函数,例如`compareValuesUsingEqualOperator($value1, $value2, $value3)`; 2. 在函数中使用条件语句`if`来判断3个参数是否相等,即`$value1 == $value2 && $value2 == $value3`; 3. 如果3个参数相等,返回`true`;如果不相等,返回`false`。 代码示例: “`php function compareValuesUsingE...
AI代码解释 $x=5;$y='5';if($x!==$y){echo'x does not equal y';}else{echo'x equals y';} 上面的代码将输出“x does not equal y”,因为不全等于运算符不会尝试将两个操作数转换为相同的类型,所以$x的类型为整数,而$y的类型为字符串。
