PHP，从数组中删除？

Question

我正在通过一系列国家进行搜索，看看是否有匹配的英国，如果是的话，我把它拉出来，放在我的下拉列表顶部。

foreach($this->registry->stockistCountries as $value) 
{ 
    if($value['country'] == 'UK'){ 
     $buffer .= '<option>UK</option>'; 
     $buffer .= '<option disabled>------------------</option>'; 
    } 

} 

我想知道，如果英国被发现，有没有办法将它从数组$ this-> registry-> stockistCountries？

感谢

Answer 1

你的循环更改为：

foreach($this->registry->stockistCountries as $i => $value) 
{ 
    if($value['country'] == 'UK'){ 
     $buffer .= '<option>UK</option>'; 
     $buffer .= '<option disabled>------------------</option>'; 
     unset($this->registry->stockistCountries[$i]); 
    } 

}

只是改变你的foreach -loop也拿到了钥匙，然后只用unset()：

foreach($this->registry->stockistCountries as $key => $value){ 
            // add this ^^^^^^^^ 
    // do something 
    if(/* whatever */){ 
    unset($this->registry->stockistCountries[$key]); 
    } 
} 

Answer 3

喜欢的东西 @unset($this->registry->stocklist['country']['UK']);

Answer 4

$found = array_search('UK', $this->registry->stockistCountries); //search for UK 


unset($this->registry->stockistCountries[$found]); // Remove from array
