[PHP][学习笔记][CURL]监测设备运行情况小demo

1.curl获取的web content 不能直接echo到页面，会造成js各种错误

2.想办法处理字符串的截取、拼接

2.1.裁剪html返回的字符串

function cutStringFrom($mainStr,$toCunSampleStr){
        //    保存要被裁剪的字符串
        $cuttedStr = $mainStr;
        //    要裁剪的字符串样本
        $targetString = $toCunSampleStr;
        //    先找到 样本字符串 位置
        $index = strpos($cuttedStr,$targetString);
        //    样本字符串长度
        $targetStringLength = strlen($targetString);
        //    开始截断
        $cuttedStr = substr($cuttedStr,$index + $targetStringLength);
        //    返回截断后结果
        return $cuttedStr;
    }

2.2.从字符串的最前面两个双引号之前取出数值

function getStringBetweenDoubleMarks($mainStr){
        //    保存要查找内容的原字符串
        $cuttedStr = $mainStr;
        //    找到第一个"
        $strRemovedFirstMark = cutStringFrom($cuttedStr,"\"");
        $indexNextMark = strpos($strRemovedFirstMark,"\"");
        $valueBetweenDoubuleMark =  substr($strRemovedFirstMark,0,$indexNextMark);
        return $valueBetweenDoubuleMark;
    }

2.3获取设备呼叫统计参数

function getCallSummary($html){
        $htmlContent = $html;
        $propertyValue = array();
        $propertyName = array("g_WebPort","kIpAddress","sysName","CALLTIME","CALLTOTALNUMBER","IPCALLTOTALNUMBER","IPCALLTOTALTIME","PERCENT_IP_CALLS","ISDNCALLTOTALNUMBER","ISDNCALLTOTALTIME","PERCENT_ISDN_CALLS");
        foreach ($propertyName as $value){
            $htmlContent = cutStringFrom($htmlContent,$value);
            $propertyValue[] = getStringBetweenDoubleMarks($htmlContent);
        }
        return $propertyValue;
    }
