There are many array methods for deleting empty elements. Today I will introduce two classic methods. One uses the array_filter function, and the other also uses the function to call a custom function.

( [0] => Yiju Tutorial Network
The code is as follows
 代码如下 复制代码

$str1_array=array('一聚教程网','','http://www.bKjia.c0m','','1654','');
$str1_array=array_filter($str1_array);
print_r($str1_array);
?>

结果


Array
(
[0] => 一聚教程网
[2] => http://www.bKjia.c0m
[4] => 1654
)

Copy code


$str1_array=array('Yiju Tutorial Network','','http://www.bKjia.c0m','','1654',''); $str1_array=array_filter($str1_array);
 代码如下 复制代码

$fangId = PostGet('houseId'); // 取得地址栏值
 $tempArray = array_filter(explode('_',$fangId),"filter"); //以__分成数组并且删除空数组
 
 if( is_array($tempArray) && !empty( $tempArray ) ) //判断数组是否有值
 {
  print_r($tempArray); //测试输出
 }
 else
 {
  MessAge('请选择对比较楼盘','list.php');
 }
 

 function filter($var)  处理函数
 {
   if($var == '')
   {
    return false;
   }
   return true;
 }

print_r($str1_array);

?>

Results


Array
[2] => http://www.bKjia.c0m [4] => 1654

)

Example
The code is as follows Copy code
$fangId = PostGet('houseId'); // Get the address bar value $tempArray = array_filter(explode('_',$fangId),"filter"); //Divide into arrays with __ and delete empty arrays if( is_array($tempArray) && !empty( $tempArray ) ) //Determine whether the array has a value
{
print_r($tempArray); //Test output } else { MessAge('Please select the property to compare','list.php'); } function filter($var) processing function { if($var == '') { Return false; } Return true; } Test method:/compare.php?houseId=2306__2307__2303__2308 For more details, please see: http://www.bKjia.c0m/phper/21/b427d2b7535fc76ad744d41f825590dc.htm http://www.bkjia.com/PHPjc/632255.htmlwww.bkjia.comtruehttp: //www.bkjia.com/PHPjc/632255.htmlTechArticleThere are many array methods to delete empty elements.

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
