foreach循环用于遍历数组中的每个元素,并执行相应的操作。 foreach循环可以遍历关联数组和索引数组。 foreach循环语法简单,通常使用foreach关键字,后面跟着被遍历的数组和一个循环体。 在循环体中,可以使用foreach语句中定义的变量来访问当前元素的值。 foreach循环会自动将数组中的指针指向下一个元素,直到所有元素都被遍历
Tobreak a foreach loopmeans we are going to stop the looping of an array without it necessarily looping to the last elements because we got what is needed at the moment. Break out of foreach loop: Example 1 Here, we have an array of the names and breaking the loop execution when a ...
Within every iteration, the loop code block uses the current element the array pointer points at and tests for the conditional that will execute thebreakoperation. If the conditional is true, the code breaks out of the loop, and if false, it continues to the next iteration. ...
