How PHP uses the array_search function to implement array search

The example in this article describes how PHP uses the array_search function to implement array search. Share it with everyone for your reference. The specific implementation method is as follows:

1 2 3 4 5 6 7 8 9

$array = array(4,5,7,8,9,10); $found = array_search(8, $array); //调用array_search函数并输出查找结果 if($found) //如果找到输出键 echo "已找到，键为".$found; else //如果没有找到输出错误信息 echo "没有找到"; ?>

$array = array(4,5,7,8,9,10);

$found = array_search(8, $array);

//Call the array_search function and output the search results

<🎜>if($found) //If the output key is found<🎜> <🎜>echo "Found, key is ".$found;<🎜> <🎜>else //If not found, output error message<🎜> <🎜>echo "not found";<🎜> <🎜>?>
