Question

我有一个这种格式的文本文件，我希望将其转换为格式化后的数组。

文本文件内容：

Header = "This is header"
Object class = "First"

min_size = 0 
max_size = 727.555 
content= true 
size = 1 
item []: 
    item [1]:
        class = "Convert" 
        name = "CONTENT" 
        min_size = 0 
        max_size = 727.555 
        intervals: size = 474 
        intervals [1]:
            min_size = 0 
            max_size = 13.139997023062838 
            type = "" 
        intervals [2]:
            min_size = 13.139997023062838 
            max_size = 14.763036269953904 
            type = "this is a type" 
        intervals [3]:
            min_size = 14.763036269953904 
            max_size = 17.01 
            type = "" 
        intervals [4]:
            min_size = 17.01 
            max_size = 18.193 
            type = ""

如果可能，我想将其转换为类似的数组：

Array
(
    [1] => 
        Array(
                ['min_size'] = 0,
                ['max_size'] = 13.139997023062838,
                ['type'] = ""
            )
    [2] => 
        Array(
                ['min_size'] = 13.139997023062838,
                ['max_size'] = 14.763036269953904,
                ['type'] = "this is a type"
            )

我已经尝试过这样的事情：

$file = "array.txt";// Your Temp Uploaded file
$cols = array();
ini_set('auto_detect_line_endings', true);

$fh = fopen($file, 'r');
$i = 0;

while (($line = fgetcsv($fh, 1000, "\t")) !== false) {
  $cols[] = $line;

  }

echo "<pre>";
print_r($cols); 
echo "</pre>";

但这只会把所有东西都变成一个阵列。

这可能吗？

包含preg_match_all，array_map和array_combine函数的复杂解决方案：

$data = file_get_contents('array.txt');
$pat = '/intervals \[\d+\]:\s+\Kmin_size = (?P<min_size>\d+(\.\d+)?) \
        \s+max_size = (?P<max_size>\d+(\.\d+)?)\s+type = "(?P<type>[^"]*)"/m';

preg_match_all($pat, $data, $m);
$result = array_map(function($a){
    return array_combine(['min_size', 'max_size', 'type'], $a);
}, array_map(null, $m['min_size'], $m['max_size'], $m['type']));

print_r($result);

输出：

Array
(
    [0] => Array
        (
            [min_size] => 0
            [max_size] => 13.139997023062838
            [type] => 
        )

    [1] => Array
        (
            [min_size] => 13.139997023062838
            [max_size] => 14.763036269953904
            [type] => this is a type
        )

    [2] => Array
        (
            [min_size] => 14.763036269953904
            [max_size] => 17.01
            [type] => 
        )

    [3] => Array
        (
            [min_size] => 17.01
            [max_size] => 18.193
            [type] => 
        )
)

使用它的当前格式将.txt文件内容转换为多维数组
