方法代码：
function deleteSegment($vsuuid) {
$num = db("test")->exec("DELETE FROM t_segment_index WHERE vs_uuid='$vsuuid'");
if($num == 1) {
$del = db("test")->exec("DELETE FROM t_video_segment WHERE vs_uuid='$vsuuid'");
if($del == 1){
$vsu = $vsuuid;
$videoMsg = db("test")->getQuery("SELECT * FROM `t_video` where v_segments_list like '%$vsuuid%' limit 1");
if(empty($videoMsg))
return $del;
$segments = $videoMsg[0]["v_segments_list"];
$v_uuid = $videoMsg[0]["v_uuid"];
$oldSegmentArray = explode("\n", $segments);
$newSegmentArray = array_filter($oldSegmentArray, function($s){
if($s === $vsuuid)
return false;
else
return true;
});
$newSegments = implode("\n", array_values($newSegmentArray));
$updateV = db("test")->exec("UPDATE t_video SET v_segments_list = '$newSegments' WHERE v_uuid='$v_uuid'");
return 1;
} else
return 0;
} else
return 0;
}
代码执行到if($s === $vsuuid)的时候报错如下：
Notice: Undefined variable: vsuuid in /Applications/XAMPP/xamppfiles/htdocs/waaa-web/runtime/service_Admin.php on line 1526
请问是什么原因导致的？该怎么解决呢？

array_filter($oldSegmentArray, function($s) use($vsuuid) {
return $s !== $vsuuid;
});
顺便帮你改下下函数...
function deleteSegment($vsuuid) {
$res = db("test")->exec("DELETE FROM t_segment_index, t_video_segment WHERE vs_uuid='$vsuuid'");
if( !$res ) return 0;
$videoMsg = db("test")->getQuery("SELECT * FROM `t_video` where v_segments_list like '%$vsuuid%' limit 1");
if( empty($videoMsg) ) return 0;
$segments = $videoMsg[0]["v_segments_list"];
$v_uuid = $videoMsg[0]["v_uuid"];
$oldSegmentArray = explode("\n", $segments);
$newSegmentArray = array_filter($oldSegmentArray, function($s) use($vsuuid) { return $s !== $vsuuid; });
$newSegments = implode("\n", array_values($newSegmentArray));
return $updateV = db("test")->exec("UPDATE t_video SET v_segments_list = '$newSegments' WHERE v_uuid='$v_uuid'");
}
闭包(Closure) 中使用外部函数，function($param) use($otherParam){}
