The PHPforeachloop provides an easy way to iterate over arrays. It works only on arrays and objects, automatically advancing through each element. The foreach construct is essential for array manipulation in PHP
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...
