java與php的memcached的資料讀取問題

一直用JAVA讀寫memcached沒出問題 
今天與PHP系統對接的時候，一直取不到PHP儲存的元素，但是PHP又取得到JAVA這邊儲存的元素。 
最後裝了MemAdmin，查看了一下，PHP儲存的元素的Flags全是0，而java使用類別庫儲存的字元型的Flags是32。讓PHP修改下儲存的Flags後問題解決。 
附帶下幾種類型的Flags： 

Java代碼  

public static final int MARKER_BYTE             = 1;  
public static final int MARKER_BOOLEAN          = 8192;  
public static final int MARKER_INTEGER          = 4;  
public static final int MARKER_LONG             = 16384;  
public static final int MARKER_CHARACTER        = 16;  
public static final int MARKER_STRING           = 32;  
public static final int MARKER_STRINGBUFFER     = 64;  
public static final int MARKER_FLOAT            = 128;  
public static final int MARKER_SHORT            = 256;  
public static final int MARKER_DOUBLE           = 512;  
public static final int MARKER_DATE             = 1024;  
public static final int MARKER_STRINGBUILDER    = 2048;  
public static final int MARKER_BYTEARR          = 4096;
