<?php/** * @author mzxy * @copyright * @param PHP List *//**** node class */class node{private $Data;//node data private $Next;  /Next node Public function SetData ($value) {$this->data= $value;  The Public Function Setnext ($value) {$this->next= $value;  } public Function GetData () {return $this->data;  } public Function GetNext () {return $this->next;    The Public function __construct ($data, $next) {$this->setdata ($data);  $this->setnext ($next);    }}//function class linklist{private $header;//head node private $size;//Length Public Function GetSize () {$i = 0;    $node = $this->header;      while ($node->getnext ()!=null) {$i + +;    $node = $node->getnext ();  } return $i;  The Public Function SetHeader ($value) {$this->header= $value;  } public Function GetHeader () {return $this->header; } public Function __construct () {header ("content-type:text/html;    Charset=utf-8 ");  $this->setheader (New Node (Null,null)); }/** * @author mzxy * @param $data--Data to be added to the node * */Public Function Add ($data) {$node = $this->header;    while ($node->getnext ()!=null) {$node = $node->getnext ();  } $node->setnext (new node ($data, null));    }/** * @author mzxy * @param $data-Data to remove the node * */Public Function removeAt ($data) {$node = $this->header;    while ($node->getdata ()! = $data) {$node = $node->getnext ();    } $node->setnext ($node->getnext ());  $node->setdata ($node->getnext ()->getdata ());    }/** * @author mzxy * @param traversal * * */Public function get () {$node = $this->header;      if ($node->getnext () ==null) {print ("The DataSet is empty!");    Return      } while ($node->getnext ()!=null) {print ($node->getnext ()->getdata ());      if ($node->getnext ()->getnext () ==null) {break;}    $node = $node->getnext (); }}/** * @author mzxy * @param $data-The data of the node to be accessed * @param This method only demonstrates no practical meaning * */Public Function getAt ($data) {$ Node= $this-&GT;HEADER-&GT;GETNExt ();      if ($node->getnext () ==null) {print ("The DataSet is empty!");    Return      } while ($node->getdata ()! = $data) {if ($node->getnext () ==null) {break;}    $node = $node->getnext ();      } return $node->getdata ();  }/** * @author mzxy * @param $value--The original data of the node that needs to be updated--$initial---updated data * */Public Function update ($initial, $value)     {$node = $this->header->getnext ();      if ($node->getnext () ==null) {print ("The DataSet is empty!");    Return      } while ($node->getdata ()! = $data) {if ($node->getnext () ==null) {break;}    $node = $node->getnext ();     } $node->setdata ($initial); }}?>
