我有这个脚本

$todos=array(
    '0' => array('id' => 46, 'nombre' => 'b2 miami downtown','precio' => 149.01,'tipo' => 'expedia'),
    '1' => array('id' => 242,'nombre' => 'b2 Miami Downtown','precio' => 176.98,'tipo' => 'hotelbeds'),
    '2' => array('id' => 240,'nombre' => 'b2 Miami Downtown','precio' => 131.62,'tipo' => 'hotelbeds'),
    '3' => array('id' => 241,'nombre' => 'b2 Miami Downtown','precio' => 131.62,'tipo' => 'hotelbeds'),
    '4' => array( 'id' => 178,'nombre' => 'Z Ocean Hotel South Beach','precio' => 400.93,'tipo' => 'expedia'),
    '5' => array( 'id' => 254,'nombre' => 'Whitelaw Hotel','precio' => 142.29,'tipo' => 'hotelbeds'),
    '6' => array( 'id' => 124, 'nombre' => 'Whitelaw Hotel','precio' => 132.04,'tipo' => 'tourico'),
    '7' => array( 'id' => 62, 'nombre' => 'Westin Colonnade Coral Gables','precio' => 138.39,'tipo' => 'tourico'),
    '8' => array( 'id' => 275, 'nombre' => 'Westgate South Beach','precio' => 166.79,'tipo' => 'hotelbeds'),
    '9' => array( 'id' => 44, 'nombre' => 'W South Beach','precio' => 374.55,'tipo' => 'tourico'),
    '10' => array( 'id' => 206, 'nombre' => 'Holiday Inn Express West Doral Miami Airport','precio' => 103.22,'tipo' => 'hotelbeds'),
    '11' => array( 'id' => 117, 'nombre' => 'Holiday Inn Express Miami International Airport','precio' => 106.3,'tipo' => 'expedia'),
    '12' => array( 'id' => 114, 'nombre' => 'Holiday Inn Express Miami Airport Doral Area','precio' => 113,'tipo' => 'tourico'),
    '13' => array( 'id' => 78, 'nombre' => 'Holiday Inn Express Doral','precio' => 93.36,'tipo' => 'expedia'),
    '14' => array( 'id' => 62, 'nombre' => 'Holiday Inn Express & Suites Kendall East Miami','precio' => 128.46,'tipo' => 'expedia'),
    '15' => array( 'id' => 18, 'nombre' => 'Best Western Plus Kendall Hotel & Suites','precio' => 429.55,'tipo' => 'tourico'),
    '16' => array( 'id' => 19, 'nombre' => 'Best Western Plus Kendall Hotel & Suites','precio' => 429.55,'tipo' => 'expedia'),
    '17' => array( 'id' => 120, 'nombre' => 'Best Western Kendall Hotel & Suites','precio' => 114.27,'tipo' => 'expedia'),
    '18' => array( 'id' => 69, 'nombre' => 'Holiday Inn Express & Suites Kendall','precio' => 126.5,'tipo' => 'expedia'));

    echo "<pre>";
    print_r($todos);

    function comp($a,$b){
        if(soundex($a['nombre'])==soundex($b['nombre'])) return($a['precio']-$b['precio']);
        if(soundex($a['nombre'])!=soundex($b['nombre'])) return strcmp($a['nombre'], $b['nombre']);
    }
    usort($todos,'comp');
    print_r($todos);
    echo "<pre>";

我需要对数组进行排序,首先按酒店名称,然后按价格(precio)对每个酒店进行排序。使用soundex的原因,是因为同一家酒店可能有不同的名称,具体取决于提供者(proveedor),所以我需要将酒店分组,并把最低价格放在第一位,然后删除其他酒店,这样我就可以只提供最好的了价格。

)

如您所见,“b2 Miami Downtown”应该在数组的顶部而不是最后一个。

请帮助解决这个问题。

谢谢!!!。

来自strcmp的 PHP 手册:

请注意,此比较区分大小写。

字母 AZ 出现字母 az 之前。请尝试使用strcasecmp

编辑:即使使用 strcasecmp,请注意它的不区分大小写仅适用于英文字符集。如果您在其他语言环境中使用名称(西班牙语、法语、德语,您自己命名),这些非基本 ASCII 字符仍将以二进制方式进行比较。例如,

posada el Ñandú rengo不等于posada el ñandÚ rengo

在比较之前,您可能需要使用多字节字符串函数,例如 mb_convert_case 或 mb_strtolower。
