public function testReplace() { 
        $post_xml_data='asdsa&(123123)';
        // dd(preg_replace('/&(?!#?[a-z0-9]+;)/', '&', $post_xml_data));
    
        $subject = 'asdsa&(123123)<Macro Name="XXX_EN_AUDIO_CODEC_TYPE" Value="(XXX_EN_AUDIO_FEATURE_XXX<<0|XXX_EN_AUDIO_FEATURE_XXX<<1|XXX_EN_AUDIO_FEATURE_XXX<<2|XXX_EN_AUDIO_FEATURE_XXX<<3 |XXX_EN_AUDIO_FEATURE_XXX<<4|XXX_EN_AUDIO_FEATURE_XXX<<5|XXX_EN_AUDIO_FEATURE_XXX<<6|XXX_EN_AUDIO_FEATURE_XXX<<7 |XXX_EN_AUDIO_FEATURE_XXX<<8|XXX_EN_AUDIO_FEATURE_XXX<<9|XXX_EN_AUDIO_FEATURE_XXX<<10|XXX_EN_AUDIO_FEATURE_XXX<<16 |XXX_EN_AUDIO_FEATURE_XXX<<17)"/> <Macro Name="XXX_EN_AUDIO_EFFECT_ITEM" Value="0"/> <Macro Name="XXX_EN_AUDIO_FEATURE_XXX" Value="1"/>';
        $new = preg_replace_callback('/($[^$]*\))/', function($matches){ 
            dump($matches);
            return str_replace(['<','>'], ['<','>'], $matches[0]);

还有一个加强版的函数，接收一组正则作为键，回调函数作为值的批量替换：

$subject = 'Aaaaaa Bbb';
    
    preg_replace_callback_array(
        [
            '~[a]+~i' => function ($match) { 
                echo strlen($match[0]), ' matches for "a" found', PHP_EOL;
            },
            '~[b]+~i' => function ($match) { 
                echo strlen($match[0]), ' matches for "b" found', PHP_EOL;
            }
        ],
        $subject
    );
