preg_replace("/(\s|\ \;| |\xc2\xa0)/","",$content);

中文空格这里面有好几种:没有简单的解决问题的方式,比如半角全角空格,比如段落符都会显示为空白的,然后让人们误解它是空格,所以去掉空格之前一定要先确认自己的是不是空格,我下面分析一下这两种的解决办法。
(1)/[\s| ]+/这个就可以,注意|后面的跟的是全角空格
(2)mb中的正则替换也可以试试
另外注意使用Unicode的时候,加上正则表达式描述符u
但由于汉语中显示为空格模样的有很多个,比如说我下面碰到的这么一个,它的unicode编码为C2A0,使用下面的表达式就能解决问题。
$new['content'] = preg_replace('/^[(\xc2\xa0)|\s]+/', '', $new['content']);
这里有个细节: \xc2a0本来是一个Unicode字符,但是不能匹配多个,只能替换一个,【这里可能是因为字节的原因】后来突然找到这么一种写法,解决了问题,另外为了避免,中文空格和英文空格相混杂的情形,后面又加了个\s来清除。
