php常用函数集合

1.curl操作

POST方式

public static function httpPost($url, $param = '')
{
    $ch1 = curl_init();
    if (version_compare(PHP_VERSION, '5.5.0', '>')) {
        curl_setopt($ch1, CURLOPT_SAFE_UPLOAD, false);
    }

    curl_setopt($ch1, CURLOPT_URL, $url);
    curl_setopt($ch1, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch1, CURLOPT_SSL_VERIFYHOST, false);
    if (!empty($param)) {
        curl_setopt($ch1, CURLOPT_POST, 1);
        curl_setopt($ch1, CURLOPT_POSTFIELDS, $param);
    }
    curl_setopt($ch1, CURLOPT_RETURNTRANSFER, 1);
    $result = curl_exec($ch1);
    curl_close($ch1);
    return $result;
}

GET方式

public static function httpGet($url)
{
    $oCurl = curl_init();
    if (stripos($url, "https://") !== false) {
        curl_setopt($oCurl, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($oCurl, CURLOPT_SSL_VERIFYHOST, false);
    }
    curl_setopt($oCurl, CURLOPT_URL, $url);
    curl_setopt($oCurl, CURLOPT_RETURNTRANSFER, 1);
    $sContent = curl_exec($oCurl);
    $aStatus  = curl_getinfo($oCurl);
    curl_close($oCurl);
    if (intval($aStatus["http_code"]) == 200) {
        return $sContent;
    } else {
        return false;
    }
}

        $val_before = $val;
        for ($i = 0; $i < sizeof($ra); $i++) {
            $pattern = '/';
            for ($j = 0; $j < strlen($ra[$i]); $j++) {
                if ($j > 0) {
                    $pattern .= '(';
                    $pattern .= '(&#[xX]0{0,8}([9ab]);)';
                    $pattern .= '|';
                    $pattern .= '|(&#0{0,8}([9|10|13]);)';
                    $pattern .= ')*';
                }
                $pattern .= $ra[$i][$j];
            }
            $pattern .= '/i';
            $replacement = substr($ra[$i], 0, 2) . '<x>' . substr($ra[$i], 2);
            $val         = preg_replace($pattern, $replacement, $val);
            if ($val_before == $val) {
                $found = false;
            }
        }
    }
    return $val;
}    

3.JSON中文转码

public static function cn_arr_json($arr)
{
    $_var = self::var_urlencode($arr);
    $_str = json_encode($_var);
    return urldecode($_str);
}
public static function var_urlencode($var)
{
    if (empty($var)) {return false;} //判断参数是否为空
    if (is_array($var)) {
        //判断是否为数组
        foreach ($var as $k => $v) {
            if (is_scalar($v)) {
                //if用来处理不是数组的情况

            } else {
                $var[$k] = self::var_urlencode($v); //else用来处理数组
            }
        }
    } else {
        $var = urlencode($var); //用来处理数组
    }
    return $var;
}

}

//导出数据，但是不是Excel表格，优点：导出的数据量比较大
*@param $datas array 设置表格数据

7.生成随机验证码
function getCode()
{

$str = "QWERTYUIOPASDFGHJKLZXCVBNM1234567890qwertyuiopasdfghjklzxcvbnm";
return substr(str_shuffle($str),26,10);

8.判断手机号归属地
function phoneCity($account)

$newArr = json_decode($res,true);
return $newArr['ContractRoot']['SvcCont']['SOO'][0]['PHONE_LATN_TYPE_RES'][0]['LATN_ID'];

}
9.成功或失败返回ajax

/**
 * 将错误信息返回给Ajax请求
 * @param string $msg 错误信息描述
 * @param integer $code 错误代码，默认1
 */
public function ajaxError($msg = '', $code = 1)
{
    $this->ajaxEcho([
        'error' => $code,
        'msg' => $msg,

}

/**
 * 将成功信息返回给Ajax请求
 * @param mix $data 返回数据
 */
public function ajaxSuccess($data = '')
{
    $this->ajaxEcho([
        'error' => 0,
        'data' => $data,
    ]);
}

/**
 * 一般情况下直接使用ajaxSuccess和ajaxError可以满足绝大部分需求
 * 考虑灵活性，本函数设置为公开，以满足特殊需求
 */
public function ajaxEcho($arr)
{
    header('Content-type:application/json;charset=utf-8');
    echo json_encode($arr);
    exit;

        $rule       =   $validate[strtolower($rule)];
    return preg_match($rule,$value)===1;
}    

11.将xml转为array
public function FromXml($xml)

{    
    if(!$xml){
        throw new WxPayException("xml数据异常！");
    }
    //将XML转为array
    //禁止引用外部xml实体
    libxml_disable_entity_loader(true);
    $this->values = json_decode(json_encode(simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA)), true);        
    return $this->values;
}

12.输出xml字符

public function ToXml()
{
    if(!is_array($this->values) 
        || count($this->values) <= 0)
    {
        throw new WxPayException("数组数据异常！");
    }
    
    $xml = "<xml>";
    foreach ($this->values as $key=>$val)
    {
        if (is_numeric($val)){
            $xml.="<".$key.">".$val."</".$key.">";
        }else{
            $xml.="<".$key."><![CDATA[".$val."]]></".$key.">";
        }
    }
    $xml.="</xml>";
    return $xml; 
}
