Question

我在转置字符串响应 fgets() 时遇到问题 ...

响应是这样的...

如何将其格式化为 Table 或至少格式化为数组格式...

这里有人吗？..非常感谢！！非常感谢！！！

它类似于一个csv文件，但是，似乎出现了多个空格。 header 行似乎有没有空格的字段名称。所以让我们找到字段位置并计算字段长度。然后创建一个正则表达式，它仅按字段的长度获取字段。最后我们 trim 字段，删除不需要的空格。

$csv = <<< '_END_'

$lines = preg_split('~\r?\n~', $csv);


// word begin/end with no space behind (=word begin only)

$pos_fields=$pos_fields[0];

$regexp = '';
$pos = $pos_fields[0][1];

// (.{10}) for a field width 10
for($i = 1; $i < count($pos_fields); $i++)
  $regexp .= '(.{' . ($pos_fields[$i][1] - $pos_fields[$i - 1][1]) . '})';

$regexp = "/$regexp(.*)/";
$arr = [];

for($i = 0; $i < count($lines); $i++)
{
  preg_match($regexp, $lines[$i], $line);
  array_shift($line);
  array_walk($line, function(&$val, $k)  { $val= $arr[$k] = chop($val); });
  $arr[] = $line;
