I'm trying to sort a PHP Array, but can't figure out how

如何在PHP中转换如下所示的数组：

Array ( 
      [2] => B.eot
      [3] => B.ttf
      [4] => CarnevaleeFreakshow.ttf
      [5] => CarnevaleeFreakshow.eot
      [6] => TRASHED.ttf
      [7] => sub.ttf
      )

看起来像这样：

Array(
     [B]=>array(
               [0] => B.eot
               [1] => B.ttf
               )
     [CarnevaleeFreakshow]=>array(
               [0] => CarnevaleeFreakshow.ttf
               [1] => CarnevaleeFreakshow.eot
               )
     [TRASHED]=>array(
               [0] => TRASHED.ttf
               )
     [sub]=>array(
               [0] => sub.ttf
               )
     )

做这样的事有名字吗？正在从中检索数据

 scandir

数组。

<?php
$data = array ( 
  2 => 'B.eot',
  3 => 'B.ttf',
  4 => 'CarnevaleeFreakshow.ttf',
  5 => 'CarnevaleeFreakshow.eot',
  6 => 'TRASHED.ttf',
  7 => 'sub.ttf'
 ); 
$new_data = array();
foreach ( $data as $value ) {
    $tmp = explode( '.', $value );
    $ext = '';
    if ( $tmp[1] ) $ext = '.' . $tmp[1];
    $new_data[ $tmp[0] ][] = $tmp[0] . $ext;
}
print_r( $new_data );
?>

下面是一个例子。

它可以写得更短，但我认为这是最有启发性的。

$ARRraw = array (
      "B.eot",
      "B.ttf",
      "CarnevaleeFreakshow.ttf",
      "CarnevaleeFreakshow.eot",
      "TRASHED.ttf",
      "sub.ttf"
      ) ;

$sorted = array();
foreach($ARRraw as $one){
  $firstPoint = strpos($one,".");
  // No point? then skip.
  if (!($firstPoint === false)){
    // Get the part before the point.
    $myKey = substr($one,0,$firstPoint);
    $sorted[$myKey][] = $one;
  }
}

做这样的事有名字吗？

没有。无论如何，使用循环应该相当简单：

<?php
$newArray = array( );
foreach( $originalArray as $fontfile ) {
    $newArray[basename( $font )][] = $fontfile;
}
echo '<pre>' . print_r( $newArray, true );

据我所知，没有"简单"的方法可以做到这一点。不过，您可以构建一个函数来处理它。

function convertArray($array) {
    $newArray = array();
    foreach( $array as $item ) {
        $newArray[basename($item)] = $item;
    }
    return $newArray;
}

这应该是你想要的。

试试看：

function subdiv(array $arr) {
$res = array();
foreach($arr as $val) {
    $tmp = explode('.', $val);
    if(!isset($res[$tmp[0]]))
        $res[$tmp[0]] = array();
    $res[$tmp[0]][] = $val;
} return $res;
}

与一起使用

$res = subdiv($array);
var_dump($res);
