php獲取td

㈠ think php 後台如何獲取 文本框裡面的值

第一種表單提交

<script>
//地址添加提交
$(function(){
$('#address_submit').click(function(){
layer.load(1,{time:1000});
varselect_country=$('#select_countryoption:selected').text();//select框
varselect_province=$('#select_provinceoption:selected').text();
varselect_city=$('#select_cityoption:selected').text();
varconsignee=$('#consignee').val();
varphone=$('#phone').val();
varaddress_detail=$('#address_detail').val();
if(!select_country||!select_province||!consignee||!phone||!address_detail){
layer.msg('',{icon:2,offset:'100px',time:'1200'});
}
$.post("{:U('User/addAddress')}",{
'select_country':select_country,
'select_province':select_province,
'select_city':select_city,
'consignee':consignee,
'phone':phone,
'address_detail':address_detail,
},function(data){
if(data=='success'){
layer.msg('operationsuccess',{icon:1,offset:'100px',time:'1000'});
setTimeout("window.location.reload()",1000);
}
else{
if(data=='no_session'){
layer.msg('',{icon:2,offset:'100px',time:'1000'});
setTimeout("location.href='{:U("index/Login/login")}'",1000);
returnfalse;
}
layer.msg(JSON.stringify(data),{icon:2,offset:'100px',time:'1500'});
returnfalse;
}
},'json');
});
})
</script>

㈡ php讀取文本文件內容～

示例代碼1: 用file_get_contents 以get方式獲取內容
代碼如下:
<?php
$url='';
$html=file_get_contents($url);
//print_r($http_response_header);
ec($html);
printhr();
printarr($http_response_header);
printhr();
?>

示例代碼2: 用fopen打開url, 以get方式獲取內容
代碼如下:
<?
$fp=fopen($url,'r');
printarr(stream_get_meta_data($fp));
printhr();
while(!feof($fp)){
$result.=fgets($fp,1024);
}
echo"url body:$result";
printhr();
fclose($fp);
?>

示例代碼3：用file_get_contents函數,以post方式獲取url
代碼如下:
<?php
$data=array('foo'=>'bar');
$data=http_build_query($data);
$opts=array(
'http'=>array(
'method'=>'POST',
'header'=>"Content-type: application/x-www-form-urlencodedrn".
"Content-Length: ".strlen($data)."rn",
'content'=>$data
),
);
$context=stream_context_create($opts);
$html=file_get_contents('',false,$context);
echo$html;
?>

示例代碼4：用fsockopen函數打開url，以get方式獲取完整的數據，包括header和body
代碼如下:
<?
functionget_url($url,$cookie=false){
$url=parse_url($url);
$query=$url[path]."?".$url[query];
ec("Query:".$query);
$fp=fsockopen($url[host],$url[port]?$url[port]:80,$errno,$errstr,30);
if(!$fp){
returnfalse;
}else{
$request="GET$queryHTTP/1.1rn";
$request.="Host:$url[host]rn";
$request.="Connection: Closern";
if($cookie)$request.="Cookie:$cookien";
$request.="rn";
fwrite($fp,$request);
while(!@feof($fp)){
$result.=@fgets($fp,1024);
}
fclose($fp);
return$result;
}
}
//獲取url的html部分，去掉header
functionGetUrlHTML($url,$cookie=false){
$rowdata=get_url($url,$cookie);
if($rowdata)
{
$body=stristr($rowdata,"rnrn");
$body=substr($body,4,strlen($body));
return$body;
}
returnfalse;
}
?>

示例代碼5：用fsockopen函數打開url，以POST方式獲取完整的數據，包括header和body
代碼如下:
<?
functionHTTP_Post($URL,$data,$cookie,$referrer=""){
// parsing the given URL
$URL_Info=parse_url($URL);
// Building referrer
if($referrer=="")// if not given use this script. as referrer
$referrer="111";
// making string from $data
foreach($dataas$key=>$value)
$values[]="$key=".urlencode($value);
$data_string=implode("&",$values);
// Find out which port is needed - if not given use standard (=80)
if(!isset($URL_Info["port"]))
$URL_Info["port"]=80;
// building POST-request:
$request.="POST ".$URL_Info["path"]." HTTP/1.1n";
$request.="Host: ".$URL_Info["host"]."n";
$request.="Referer:$referern";
$request.="Content-type: application/x-www-form-urlencodedn";
$request.="Content-length: ".strlen($data_string)."n";
$request.="Connection: closen";
$request.="Cookie:$cookien";
$request.="n";
$request.=$data_string."n";
$fp=fsockopen($URL_Info["host"],$URL_Info["port"]);
fputs($fp,$request);
while(!feof($fp)){
$result.=fgets($fp,1024);
}
fclose($fp);
return$result;
}
printhr();
?>

示例代碼6:使用curl庫，使用curl庫之前，你可能需要查看一下php.ini，查看是否已經打開了curl擴展
代碼如下:
<?
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, '');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
echo $file_contents;
?>

關於curl庫：
curl官方網站
curl 是使用URL語法的傳送文件工具，支持FTP、FTPS、HTTP HTPPS SCP SFTP TFTP TELNET DICT FILE和LDAP。curl 支持SSL證書、HTTP POST、HTTP PUT 、FTP 上傳，kerberos、基於HTT格式的上傳、代理、cookie、用戶＋口令證明、文件傳送恢復、http代理通道和大量其他有用的技巧
代碼如下:
<?
functionprintarr(array$arr)
{
echo"<br> Row field count: ".count($arr)."<br>";
foreach($arras$key=>$value)
{
echo"$key=$value <br>";
}
}
?>

㈢ php 正則表達式 獲取表格的每行數據

給個正則你
(?<=<td>).*(?=</td>)
接著再用preg_replace和strip_tags這兩個函數去掉不要的html標簽

㈣ PHP怎麼獲取表單中的多條數據

在生成的表單元素以及之前的元素的名字加上中括弧即可實現
比如： name="contents" => name="contents[]"，最後提交獲取到的數據是一個數組形式的。

代碼如下：

<form name="form1" method="post" action="index.php?action=ok">
1.<input type="text" name="contents[]" value="">
2.<input type="text" name="contents[]" value="">
3.<input type="text" name="contents[]" value="">
<input type="submit" value="提交">
</form>
<?php
if($_GET['action'] == 'ok'){
$contents = $_POST['contents'];

print_r($contents);
}
?>
得到的數據是數組形式的，遍歷即可。
