How to get QQ information from QQ master with PHP, get
with PHP. This article describes the method of getting QQ information from QQ master with PHP. Share it with everyone for your reference. The specific analysis is as follows:
Add the following points:
① This is a simple routine. Through expansion, you can easily obtain tens of millions of QQ information. The $jsonUrl parameter cd=610900 is the city code
② The QQ master information has been protected from hotlinking, so I use the PHP refer to fake http://city.qq.com
③ I originally wanted to make a QQ email mass-sending software for fun, but it has no economic value. It is very simple to contribute it for everyone's reference.
The specific code is as follows:
Copy code The code is as follows:
$refer="http://city.qq.com"; //Define $refer
$opt=array('http'=>array('header'=>"Referer: $refer")); //Request header array
$context=stream_context_create($opt); //Create a sending context header information text
$jsonUrl="http://city.qq.com/json.php?mod=search&act=page&callback=showSrchResult&jsontype=str&perpage=10&cd=610900&nl=3&xb=0&type=city&pg=1";
$jsonStr = getJson($jsonUrl,$refer,$context); //Call the JSON proxy function
echo $jsonStr; //Output JSON text
//Get QQ master JSON data
function getJson($url,$referer,$context)
{
$opt=array('http'=>array('header'=>"Referer: $referer"));
$context=stream_context_create( $opt);
$getJsonStr = file_get_contents($url,false, $context);
$getJsonStr = substr($getJsonStr,0,-2);
$getJsonStr = substr($getJsonStr,15);
Return $getJsonStr;
}
?>
I hope this article will be helpful to everyone’s PHP programming design.

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

在php中,可以使用substr()函数来读取字符串后几个字符,只需要将该函数的第二个参数设置为负值,第三个参数省略即可;语法为“substr(字符串,-n)”,表示读取从字符串结尾处向前数第n个字符开始,直到字符串结尾的全部字符。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

查找方法:1、用strpos(),语法“strpos("字符串值","查找子串")+1”;2、用stripos(),语法“strpos("字符串值","查找子串")+1”。因为字符串是从0开始计数的,因此两个函数获取的位置需要进行加1处理。
