PHP，從數組中刪除？

Question

我正在通過一系列國家進行搜索，看看是否有匹配的英國，如果是的話，我把它拉出來，放在我的下拉列表頂部。

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

} 

我想知道，如果英國被發現，有沒有辦法將它從數組$ this-> registry-> stockistCountries？

感謝

Answer 1

你的循環更改爲：

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

}

只是改變你的foreach -loop也拿到了鑰匙，然後只用unset()：

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

Answer 3

喜歡的東西 @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
