用PHP在数据后循环输出文本框
思路：
1、构建form表单，输出文本框，用textarea/textarea吧，input/内不能换行，页面效果也不好（php、html代码嵌套写的话，直接写就行，建议用smarty，php与模板分离，比较清晰）-php输出文本框值
2、提交内容，确定用什么method（post、get）
3、获取内容，$str=$_POST['name']（name为textarea的name值）
4、$arr=split ('\r\n', $str);按换行符分割字符串为数组
5、循环执行插入语句，$arr每一层都是一条数据
PHP中 怎么样实现从一个文本框中读取数值然后在另一个文本框中输出呢
可以使用POST也可以使用GET方式进行传递，比如
form action="" method="post"
input type='text' name="username"
input type="submit"
/form
?php
if(isset($_POST['username']))
{
$username = $_POST['username'];
}
echo 'input type="text" value="$username"';
?
大体是这样，但是这只是个样板~~~
PHP 怎么把字符串输出到文本框
也可以这样
if($x==100)
{
input type="text" name="nox" value=“满足时候的值” /
}else{
input type="text" name="nox" value="不满足时候的值" /
}
PHP 输出文本框内容到变量 然后抓取内容
?php
header("Content-type: text/html; charset=utf-8");
if(!empty($_POST['input_text'])) {
$data = file_get_contents( $_POST['input_text'] );
$charset_pos = stripos($data,'charset');
if($charset_pos) {
if(stripos($data,'utf-8',$charset_pos)) {
echo iconv('utf-8','utf-8',$data);
}else if(stripos($data,'gb2312',$charset_pos)) {
echo iconv('gb2312','utf-8',$data);
}else if(stripos($data,'gbk',$charset_pos)) {
echo iconv('gbk','utf-8',$data);
}
return;
}
echo $data;
}else {
?
