HtmlString = "……var pictree = ['1341972991328.html','1341972991534.html','1341972991731.html','1341972991929.html','1341972992128.html','1341972992341.html','1341972992586.html','1341972992780.html','1341972992972.html','1341972993169.html','1341972993363.html','1341972993560.html','1341972993749.html','1341972993955.html','1341972994153.html'];
 //-->

字符串变量HtmlString。变量值不确定。但都存在 var pictree = [字符串1] 和 。 

如何把 字符串1 里各''里的内容和 字符串2 连接起来组成一个新的字符串？


在线等。 第一次接触PHP。谢谢老师！！
