PHP中array_splice()函数对数组元素的添加、修改、删除

array_splice() 函数从数组中可实现对数据中元素的添加、修改、删除操作,方便对数组中的值进行处理。

语法:array_splice(array,start,length,array) ,start是从0开始标记,千万不要忘记。注意添加和修改时参数是4个,删除是3个参。

添加元素:

 $array=array("你好","HELLO WORD","李雷PHP博客","学习","很快乐","是不是");echo "原数组:";var_dump($array);array_splice($array,1,0,"我是刚刚新添加的元素");echo "在第2位后添加元素:";var_dump($array);  

删除元素:

 $array=array("你好","HELLO WORD","李雷PHP博客","学习","很快乐","是不是");echo "原数组:";var_dump($array);array_splice($array,1,2);echo "从第2位开始删除2个元素:";var_dump($array);  

修改元素:

 $array=array("你好","HELLO WORD","李雷PHP博客","学习","很快乐","是不是");echo "原数组:";var_dump($array);array_splice($array,1,1,"我是刚刚新替换的元素");echo "将第2位后替换元素:";var_dump($array);
