我有一些我写的代码,它工作得很好。除了我不确定我写的是线性搜索还是半身搜索?!我对这些差异感到困惑。有人可以澄清不同之处,我的代码是什么,所以我可以向某人解释它?线性或二进制搜索? -PHP
- 下面的代码搜索用户输入的值。并通过一个CSV数据文件。然后我将所有值保存到一个新的数组中,其中包含结果。希望这是有道理的。
我只想知道我的代码是线性的还是二进制的?我得到这么困惑他们*
$SearchThis = isset($_POST['Search']) ? $_POST['Search'] : '';
//empty()
$SearchThis = !empty($_POST['Search']) ? $_POST['Search'] : '';
// Grabs the csv file (and its existing data) and makes it into an array
$csv = array();
$lines = file('data/StaffData.csv', FILE_IGNORE_NEW_LINES);
foreach ($lines as $key => $value)
{
$csv[$key] = str_getcsv($value);
}
//A new array which will display the search results
$new_csv = array();
//This displays which rows have matched the search (it is put in an array)
//Looks through full names
$keys = array_keys(array_column($csv, 0), $SearchThis); // original code
foreach($keys as $index) { // Iterate over the keys
$new_csv[] = $csv[$index]; // Copy the matching rows to our new array
}
//Looks through phone numbers
$keys = array_keys(array_column($csv, 1), $SearchThis); // original code
foreach($keys as $index) { // Iterate over the keys
$new_csv[] = $csv[$index]; // Copy the matching rows to our new array
}
//Looks through gender
$keys = array_keys(array_column($csv, 2), $SearchThis); // original code
foreach($keys as $index) { // Iterate over the keys
$new_csv[] = $csv[$index]; // Copy the matching rows to our new array
}
//Looks through Birthday
$keys = array_keys(array_column($csv, 3), $SearchThis); // original code
foreach($keys as $index) { // Iterate over the keys
$new_csv[] = $csv[$index]; // Copy the matching rows to our new array
}
//Looks through Type of work
$keys = array_keys(array_column($csv, 4), $SearchThis); // original code
foreach($keys as $index) { // Iterate over the keys
$new_csv[] = $csv[$index]; // Copy the matching rows to our new array
}
谢谢迈赫迪!这确实有道理!快速,正是我需要听到的!我无法接受你的回答,因为你回答得太快了哈哈但是我会在几分钟内接受它:-) –
不用担心,我可以帮助:D –
