需求說(shuō)明清楚啊,是點(diǎn)擊一下按鈕-30,然后再次點(diǎn)擊再次-30,。還是點(diǎn)一次按鈕,就1000-30一直循環(huán),一直到數(shù)值0,這個(gè)直接用js就能實(shí)現(xiàn)了啊,為什么用php,難道要存值?

$conn = mysql_connect("localhost","11111","22222");

用PHP向服務(wù)器發(fā)送HTTP的POST請(qǐng)求,代碼如下:
?php
/**????
*?發(fā)送post請(qǐng)求????
*?@param?string?$url?請(qǐng)求地址????
*?@param?array?$post_data?post鍵值對(duì)數(shù)據(jù)????
*?@return?string????
*/????
function?send_post($url,?$post_data)?{????
$postdata?=?http_build_query($post_data);????
$options?=?array(????
'http'?=?array(????
'method'?=?'POST',????
'header'?=?'Content-type:application/x-www-form-urlencoded',????
'content'?=?$postdata,????
'timeout'?=?15?*?60?//?超時(shí)時(shí)間(單位:s)????
)????
);????
$context?=?stream_context_create($options);????
$result?=?file_get_contents($url,?false,?$context);?????????????
return?$result;????
}
使用的時(shí)候直接調(diào)用上面定義的send_post方法:
$post_data?=?array(
'username'?=?'username',
'password'?=?'password'
);
send_post('網(wǎng)址',?$post_data);
在php中要模擬post請(qǐng)求數(shù)據(jù)提交我們會(huì)使用到curl函數(shù),下面我來(lái)給大家舉幾個(gè)curl模擬post請(qǐng)求提交數(shù)據(jù)例子有需要的朋友可參考參考。
注意:curl函數(shù)在php中默認(rèn)是不被支持的,如果需要使用curl函數(shù)我們需在改一改你的php.ini文件的設(shè)置,找到php_curl.dll去掉前面的";"就行了
例1
?php
$uri = "";
// 參數(shù)數(shù)組
$data = array (
'name' = 'tanteng'
// 'password' = 'password'
);
$ch = curl_init ();
// print_r($ch);
curl_setopt ( $ch, CURLOPT_URL, $uri );
curl_setopt ( $ch, CURLOPT_POST, 1 );
curl_setopt ( $ch, CURLOPT_HEADER, 0 );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );
$return = curl_exec ( $ch );
curl_close ( $ch );
print_r($return);
接受php頁(yè)面遠(yuǎn)程服務(wù)器:
?php
if(isset($_POST['name'])){
if(!empty($_POST['name'])){
echo '您好,',$_POST['name'].'!';
}
}
