Question

是否可以在php中转换此类数据

    ABANO TERME A001
ABBADIA CERRETO A004
ABBADIA LARIANA A005
ABBADIA SAN SALVATORE   A006
ABBASANTA   A007
ABBATEGGIO  A008
ABBIATEGRASSO   A010

到一个关联的数组，其中第一列是键，第二列是值？

Answer 1

$handle = fopen(path\to\file\filename, "r");
$result_arr = array();
while(($filesop = fgets($handle)) !== false)
{
    $line_arr = explode(" ", $filesop);
    $value = end($line_arr);
    unset($line_arr[array_search($value, $line_arr)]);
    $key = implode(" ", $line_arr);
    $result_arr[trim($key] = trim($value);
}
print_r($result_arr);

像这样存储在文本文件中（以逗号分隔）：

ABANO TERME,A001
ABBADIA CERRETO,A004
ABBADIA LARIANA,A005
ABBADIA SAN SALVATORE,A006
ABBASANTA,A007
ABBATEGGIO,A008
ABBIATEGRASSO,A010

读取文件的解决方案：

$handle = fopen(path\to\file\filename, "r");
$result_arr = array();
while(($filesop = fgets($handle)) !== false)
{
    $line_arr = explode(",", $filesop);
    $value = end($line_arr);
    unset($line_arr[array_search($value, $line_arr)]);
    $key = implode(",", $line_arr);
    $result_arr[trim($key] = trim($value);
}
print_r($result_arr);

Answer 2

    $txt = file_get_contents('foo.txt');
    $arr=array_values(array_filter(explode(' ',$txt)));
    $new=[];
    for($i=0; $i<count($arr)-1;$i++){

    $new[$arr[$i]]=$arr[++$i];
    }

    print_r($new);

Answer 3

这个特定数据的一个解决方案是：

<?php

$data = file_get_contents('data.txt')

//use regular expressions to parse whole file at once
preg_match_all("/([^\s]+\s?[^\s]+?)\s+(.\d+)$/m", $data, $m);

//and combine results from result array ($m)
//first entry - $m[0] contains whole lines thats why I dont use it here
//second entry - $m[1] - data from first brackets is an array key
//third entry - $m[2] - is a value (both are separated by some number of spaces - \s+)
$array = array_combine($m[1], $m[2]);

print_r($array);

?>

输出：

Array
(
    [ABETONE] => A012
    [ABRIOLA] => A013
    [ACATE] => A014
    [ACCADIA] => A015
)

当然，正如上面的同事所指出的，这取决于数据的来源，以及这个特定的集合是否具有代表性。
