分割文本到一个多维数组php

这就是我想出来的。

请注意代码中的注释，并注意我假设您的示例文件在发布时被更改(制表符到空格)。

如果你有一组空格作为分隔符，这将变得更加困难，因为我们可能在一个字段中有相同的一组空格(例如;书的名字)。这可能使脚本不能按预期运行。您可以将"'t"更改为" "(四个空格)，如果这是您所拥有的，您需要测试文件/字符串才能知道。

制表符是可以的，但是你不能在任何文本域中也有制表符，否则会失败。

因为这里的制表符被改为空格，所以我在下面的代码中将它们硬编码为't。

<?php
# This is basically just exploding the elements 2 times
# and getting the elements in the right order
# This will hold the array with info
$finalResult = array();
# Your input text to be parsed
# I am supposing you have TABS as delimiters and the order never changes
$inputText = <<<EOF

EOF;
# First break each line into array of lines
# If you are sure this file comes from *nix you can use 'n as newline
# If you are sure this comes from Windows you can use 'r'n
# Or you can use PHP_EOL but this use the current system as a basis for what to use
$textLines = explode("'n", $inputText);
# Now we go through each line getting all data
foreach($textLines as $line) {
    # Get each tab-separated field
    $expLine  = explode("'t", $line);
    # Sanity check
    if (count($expLine) < 8) {
        # The line does not have enough items, deal with error
        echo "Item " . (isset($expLine[0]) ? $expLine[0]." " : "") . "ignored because of errors'n";
        continue;
    }
    # new item
    # I have changed this a bit as it seems you have more fields to get than
    # what shows on your example (2 quantities, for hard and softcovers)
    $finalResult[$expLine[0]] = array(
        "author"      => $expLine[1],
        "isbn"        => $expLine[2],  
        "hardcover"   => $expLine[3],
        "hc-quantity" => $expLine[4],
        "softcover"   => $expLine[5],
        "sc-quantity" => $expLine[6],
        "e-book"      => $expLine[7],
    );
}
# Just show the data structure
var_dump($finalResult);
?>

然后是结果:

array(6) {
  ["The Boys in the Boat"]=>
  array(7) {
    ["author"]=>
    string(18) "Daniel James Brown"
    ["isbn"]=>
    string(10) "067002581X"

    string(5) "19.99"

    ["sc-quantity"]=>
    string(2) "10"
    ["e-book"]=>
    string(5) "16.25"
  }
  ["Me Before You"]=>
  array(7) {
    ["author"]=>
    string(10) "Jojo Moyes"

    string(10) "0670026603"
    ["hardcover"]=>
    string(5) "18.95"
    ["hc-quantity"]=>
    string(1) "2"
    ["softcover"]=>
    string(5) "17.50"
    ["sc-quantity"]=>
    string(1) "1"
    ["e-book"]=>
    string(5) "17.25"
  }
  ["A Thousand Splendid Suns"]=>
  array(7) {
    ["author"]=>
    string(15) "Khaled Hosseini"
    ["isbn"]=>
    string(10) "1594489505"
    ["hardcover"]=>
    string(5) "19.00"
    ["hc-quantity"]=>
    string(1) "7"
    ["softcover"]=>
    string(5) "15.50"
    ["sc-quantity"]=>
    string(1) "4"
    ["e-book"]=>
    string(5) "14.95"
  }
  ["The Wright Brothers"]=>
  array(7) {
    ["author"]=>
    string(16) "David McCullough"
    ["isbn"]=>
    string(10) "1476728742"
    ["hardcover"]=>
    string(5) "21.95"
    ["hc-quantity"]=>
    string(1) "3"
    ["softcover"]=>
    string(5) "18.95"
    ["sc-quantity"]=>
    string(1) "3"
    ["e-book"]=>
    string(5) "18.95"
  }
}

由于所有这些字符之间都有两个或两个以上的空格字符:

//create books array
$books = array();
//$text to array by each line
$arr = explode("'n",$text);
//explode and store each line
foreach ($arr as $line){
$arr2 = explode('  ',$line);
$books[] = array (
                  'name'=>trim($arr2[0]),
                  'author'=>trim($arr2[1]),
                  'isbn'=>trim($arr2[2]),
                  'hardcover'=>trim($arr2[3]),
                  'quantity'=>trim($arr2[4]),
                  'softcover'=>trim($arr2[5]),
                  'e_book'=>trim($arr2[6])
                 );
}
//the array that you want
print_r($books);

PHP允许这样做，但我没有在数组键中使用name，因为它有空间。如果你坚持，你可以修改这一行

$books[] = array (

到

$books[$arr2[0]] = array (

考虑每行是一个子数组，每个书名是一个索引，可以使用preg_match将其分割为2个或更多的空格，返回的数组的第一项是书名(索引)，另一项是子数组中的值。也就是说，你可以这样写:

<?php
$book_info_keys = array('author', 'isbn', 'hardcover', 'quantity', 'softcover', 'e-book');
$input_file = 'a.txt';
$result = array();
foreach (file($input_file) as $line) { // Read the file as an array
  // On each line, split items by 2 or more spaces
  $a = preg_split('/ {2,}/', $line);
  // Now we divide the line into two part: the first item is book name,
  // the rest is book info.
  $book_name = $a[0];
  $book_info = array();
  $i = 1; // $a[0] is book name, so the first info is at index 1
  foreach ($book_info_keys as $key) {
    $book_info[$key] = $a[$i++];
  }
  // Now insert the infos into the result array, with book name served as index
  $result[$book_name] = $book_info;
}
var_dump($result);
?>

并且，记住上面的代码不是为了在现实生活中使用而编写的。尽可能在任何地方添加错误检查，永远不要假设输入文件总是有效的(正如我在上面的代码中所假设的那样)。可能在某些行上有8、9或更多项，而在其他行上只有6、5或更少项。在这种情况下，上面的代码将会失效。
