下面的php类是我写的，它工作得很好。但是，我希望代码表示可以更专业。
它在做什么?
- 在代码末尾，FULL_SEO_URL('xxxx')触发函数FULL_SEO_URL操作类;
- 在类中，第二个方法将检查自身是否循环，并对某些处理采用第一个方法;
- 第二个方法完成后，产品将传递给第三个方法
我想问什么?
- 我怎么能全局变量内的类，但外面的方法?(例如$all_seo_url_array)，实际上该变量在所有方法中都可用;
- 我如何在类中设置$k=0的初始值?实际上，我还想重置它为0为每个FULL_SEO_URL('xxxx')的使用;
谢谢。
<?php
$k = 0; //I don't like to set $k=0 here, but it is the only way to work
class CONVERT{
public static function parent_id_to_seo_url($page_id){
$sql_parent_id_to_seo_url = "select * from ".DB_PREFIX."page
left join ".DB_PREFIX."page_contents
on ".DB_PREFIX."page.page_id = ".DB_PREFIX."page_contents.page_id
where ".DB_PREFIX."page.page_id = '".$page_id."'
and ".DB_PREFIX."page_contents.language = '".$_SESSION['frontend']['lang']."'";
$result_parent_id_to_seo_url = mysql_query($sql_parent_id_to_seo_url);
$record_parent_id_to_seo_url = mysql_fetch_assoc($result_parent_id_to_seo_url);
return $record_parent_id_to_seo_url['seo_url'];
}
public static function all_seo_url($single_seo_url){
global $all_seo_url_array; //can I global it outside the methods?
global $k; //can I global it outside the methods?
$sql_all_seo_url = "select * from ".DB_PREFIX."page
left join ".DB_PREFIX."page_contents
on ".DB_PREFIX."page.page_id = ".DB_PREFIX."page_contents.page_id
where ".DB_PREFIX."page_contents.seo_url = '".$single_seo_url."'
and ".DB_PREFIX."page_contents.language = '".$_SESSION['frontend']['lang']."'";
$result_all_seo_url = mysql_query($sql_all_seo_url);
$record_all_seo_url = mysql_fetch_assoc($result_all_seo_url);
$all_seo_url_array[$k]['seo_url'] = $record_all_seo_url['seo_url'];
$k++;
if ($record_all_seo_url['level']>1){CONVERT::all_seo_url(CONVERT::parent_id_to_seo_url($record_all_seo_url['parent_id']));} else { $k = 0; } //can I reset $k=0 at better place?
return $all_seo_url_array;
}
public static function reverse_seo_url($all_seo_url_array){
global $all_seo_url_array_reverse; //can I global it outside the methods?
$all_seo_url_array_reverse = array_reverse($all_seo_url_array);
$final_url = '';
foreach ($all_seo_url_array_reverse as $key => $value){
$final_url .= '/'.$all_seo_url_array_reverse[$key]['seo_url'];
}
return $final_url;
}
}
function FULL_SEO_URL($seo_url){
return CONVERT::reverse_seo_url(CONVERT::all_seo_url($seo_url));
}
echo FULL_SEO_URL('history'); echo "<br/>";
echo FULL_SEO_URL('other-innovations'); echo "<br/>";
?>
您可以在类中设置静态属性，如:
class myClass{
public static $myProperty = 0;
public static function myFunction(){
echo self::$myProperty;
self::$myProperty = 1;
echo self::$myProperty;
}
echo myClass::$myProperty;
# output: 0
myClass::myFunction();
# output 0 1
echo myClass::$myProperty;
# output 1
myClass::$myProperty=0;
echo myClass::$myProperty;
# output 0
我不确定我理解你所说的关于$k的全局是什么意思;
<?php
class CONVERT
{
protected $k;
function __construct()
{
$this->k = 0;
}
}
这样，您可以在所有方法中使用$this->k
可以使用构造函数跨类访问变量。
。
class testclass
{
private $global_variable;
public function __construct($global_variable)
{
$this->global_variable = $global_variable;
}
public function yourmethod()
{
$this->global_variable; // And so on
}
}
