php将textarea数据提交到mysql出现很多空格的解决方法
有一些朋友可能会发现我们在html提交给php处理保存数据到mysql中之后会发现我们再次从mysql读出数据时会有很多的空格了,那么我们如果直接在mysql中查看又没有空间,这是什么问题要如何处理呢.
textarea中总是有很多空格问题解决
问题描述:
在php读取mysql数据到textarea中开头可结尾总有很多空格,在数据表中查看数据是没有空格的.
问题原因:
内容应该顶着textarea写,textarea后不要有空格和换行.
解决方法:
代码如下:
代码如下:
echo str_replace(' ', '', 'ab ab');
//输出 "abab'
?>
或者使用
代码如下:
echo strtr('ab ab', array(' '=>''));
// 输出 "abab"
?>
补充:
php textarea中的换行符为"\r\n"
不是'\n'
不是"
"
不是'\r\n'
不是'\r'+'\n'
希望本文所述对大家的PHP程序设计有所帮助。
