Mar 17, 2017 pm 05:19 PM
本文實(shí)例講述了PHP實(shí)現(xiàn)C#山寨ArrayList的方法。分享給大家供大家參考。具體如下：
class ArrayList
{
public $length;
public $name;
public $my_array;
function __construct()
{
$this->my_array=Array();
}
public function Add($element)
{
array_push($this->my_array, $element);
}
public function get_Length()
{
$this->length=count($this->my_array);
return $this->length;
}
public function get_Element($key)
{
if(array_key_exists($key, $this->my_array))
{
echo $this->my_array[$key];
}
else
{
echo "沒(méi)有這個(gè)元素";
}
}
public function list_array()
{
foreach ($this->my_array as $value)
{
echo $value;
echo "<br/>";
}
}
public function Delete($key)
{
if(array_key_exists($key, $this->my_array))
{
$this->my_array[$key]=null;
}
else
{
echo "沒(méi)有這個(gè)元素";
}
}
public function erase_number()
{
$pattern="/[0-9]/";
foreach ($this->my_array as $value)
{
if(eregi($pattern, $value))
{
$value=null;
}
}
foreach ($this->my_array as $value)
{
echo $value;
echo "<br/>";
}
}
public function erase_char()
{
$pattern='/a-zA-Z/';
for($i=0;$i<count($this->my_array)-1;$i++)
{
if(eregi($pattern, $this->my_array[$i]))
{
$this->my_array[$i]=null;
}
}
foreach ($this->my_array as $value)
{
echo $value;
echo "<br/>";
}
}
}希望本文所述對(duì)大家的php程序設(shè)計(jì)有所幫助。

How do I embed PHP code in an HTML file?
Jun 22, 2025 am 01:00 AM
You can embed PHP code into HTML files, but make sure that the file has an extension of .php so that the server can parse it correctly. Use standard tags to wrap PHP code, insert dynamic content anywhere in HTML. In addition, you can switch PHP and HTML multiple times in the same file to realize dynamic functions such as conditional rendering. Be sure to pay attention to the server configuration and syntax correctness to avoid problems caused by short labels, quotation mark errors or omitted end labels.
What are the best practices for writing clean and maintainable PHP code?
Jun 24, 2025 am 12:53 AM
The key to writing clean and easy-to-maintain PHP code lies in clear naming, following standards, reasonable structure, making good use of comments and testability. 1. Use clear variables, functions and class names, such as $userData and calculateTotalPrice(); 2. Follow the PSR-12 standard unified code style; 3. Split the code structure according to responsibilities, and organize it using MVC or Laravel-style catalogs; 4. Avoid noodles-style code and split the logic into small functions with a single responsibility; 5. Add comments at key points and write interface documents to clarify parameters, return values ??and exceptions; 6. Improve testability, adopt dependency injection, reduce global state and static methods. These practices improve code quality, collaboration efficiency and post-maintenance ease.
