可以的
str_replace(' ', '', $row['content_tc']);
注意第一个空格是特殊的符号
<html><meta charset="utf-8"><body><?php$s =<<< TXT商号名称（中文）： 有限公司商号名称（英文）： 商号地址： 广州市经营项目： 金银币，硬币，纸币，邮票，趣味品，茶品联络人姓名（中文）： 张三联络人姓名（英文）： 电话 123232328899传真： QQ23232370566网址： 电邮： 532326603@99.comTXT;echo preg_replace("/[ \t]+/", '', $s);?></body></html> 不会换行
<?php$a="1 2 3 456 789";echo (str_replace(' ', '', $a));?> html 方式下当然不会换行！
不会换行
html 方式下当然不会换行！
你在浏览器中 查看源代码 就知道了
不会换行
preg_replace("/[ \t]+/", '', $row['content_tc']);加上这句，显示效果和原来一样
我要在显示的时候把空格去掉，保留换行
$row['content_tc'] = preg_replace("/[ \t]+/", '', $row['content_tc']);
改错都改傻了吧？
$row['content_tc'] = preg_replace("/[ \t]+/", '', $row['content_tc']);
换行没了
你的数据中只有文本换行符，html 的换行符是
这也都忘啦？
百度了一下将文本换行符替换成
$row['content_tc']=preg_replace("/\r\n/", '<br/>',$row['content_tc']); 结果不行，瞬间凌乱了。。。。。。。。
贴出你的代码好吗？感觉你的次序错了

foreach ($information as $row) { $row['content_tc']=preg_replace("/[ \t]+/", '',$row['content_tc']); $row['content_tc']=preg_replace("/\r\n/", '<br/>',$row['content_tc']); } $informationAfterHandle[] = $row; 换了顺序也不行
foreach ($information as $row) { $row['content_tc']=preg_replace("/\r\n/", '<br/>',$row['content_tc']); $row['content_tc']=preg_replace("/[ \t]+/", '',$row['content_tc']); } $informationAfterHandle[] = $row;
