直接可以拿来用的PHP常用功能代码片段(1~5)
2、PHP实现汉字转整型数字，如：一百零一 转成101
test();/** * 测试 */function test() { echo CnToInt('一'); // 1 echo CnToInt('十'); // 10 echo CnToInt('十一'); // 11 echo CnToInt('一百一十'); // 110 echo CnToInt('一千零一'); // 1001 echo CnToInt('一万零一百零一'); // 10101 echo CnToInt('一亿一千三百万零三千零一'); // 113003001 echo CnToInt('一千万亿'); // 11.0E+15}/** * 中文转数字 * @param String $var 需要解析的中文数 * @param Int $start 初始值 * @return int */function CnToInt($var, $start = 0) { if (is_numeric($var)) { return $var; } if (intval($var) === 0) { $splits = array('亿' => 100000000, '万' => 10000); $chars = array('万' => 10000, '千' => 1000, '百' => 100, '十' => 10, '一' => 1, '零' => 0); $Ints = array('零' => 0, '一' => 1, '二' => 2, '三' => 3, '四' => 4, '五' => 5, '六' => 6, '七' => 7, '八' => 8, '九' => 9, '十' => 10); $var = str_replace('零', "", $var); foreach ($splits as $key => $step) { if (strpos($var, $key)) { $strs = explode($key, $var); $start += CnToInt(array_shift($strs)) * $step; $var = join('', $strs); } } foreach ($chars as $key => $step) { if (strpos($var, $key) !== FALSE) { $vs = explode($key, $var); if ($vs[0] === "") { $vs[0] = '一'; } $start += $Ints[array_shift($vs)] * $step; $var = join('', $vs); } elseif (mb_strlen($var, 'utf-8') === 1) { $start += $Ints[$var]; $var = ''; break; } } return $start; } else { return intval($var); }}
3、PHP实现简单的对称加密和解密方法
/** * 通用加密 * @param String $string 需要加密的字串 * @param String $skey 加密EKY * @return String */function enCode($string = '', $skey = 'echounion') { $skey = array_reverse(str_split($skey)); $strArr = str_split(base64_encode($string)); $strCount = count($strArr); foreach ($skey as $key => $value) { $key < $strCount && $strArr[$key].=$value; } return str_replace('=', 'O0O0O', join('', $strArr));}/** * 通用解密 * @param String $string 需要解密的字串 * @param String $skey 解密KEY * @return String */function deCode($string = '', $skey = 'echounion') { $skey = array_reverse(str_split($skey)); $strArr = str_split(str_replace('O0O0O', '=', $string), 2); $strCount = count($strArr); foreach ($skey as $key => $value) { $key < $strCount && $strArr[$key] = rtrim($strArr[$key], $value); } return base64_decode(join('', $strArr));}
4、PHP实现数字转字母，生成Excel列标
/** * 数字转字母 （类似于Excel列标） * @param Int $index 索引值 * @param Int $start 字母起始值 * @return String 返回字母 */function IntToChr($index, $start = 65) {$str = '';if (floor($index / 26) > 0) {$str .= IntToChr(floor($index / 26)-1);}return $str . chr($index % 26 + $start);}/** * 测试 */function test() {echo IntToChr(0); //# Aecho IntToChr(1); //# B// ...echo IntToChr(27); //# AB}
5、PHP实现计算两个时间戳之间的时间长度
/** * 返回两个时间的相距时间，*年*月*日*时*分*秒 * @param int $one_time 时间一 * @param int $two_time 时间二 * @param int $return_type 默认值为0，0/不为0则拼接返回，1/*秒，2/*分*秒，3/*时*分*秒/，4/*日*时*分*秒，5/*月*日*时*分*秒，6/*年*月*日*时*分*秒 * @param array $format_array 格式化字符，例，array('年', '月', '日', '时', '分', '秒') * @return String or false */public function getRemainderTime($one_time, $two_time, $return_type=0, $format_array=array('年', '月', '日', '时', '分', '秒')){if($return_type<0 || $return_type>6){return false;}if(!(is_int($one_time) && is_int($two_time))){return false;}$remainder_seconds = abs($one_time-$two_time);//年$years = 0;if(($return_type==0 || $return_type==6) && $remainder_seconds-31536000>0){$years = floor($remainder_seconds/(31536000));}//月$monthes = 0;if(($return_type==0 || $return_type>=5) && $remainder_seconds-$years*31536000-2592000>0){$monthes = floor(($remainder_seconds-$years*31536000)/(2592000));}//日$days = 0;if(($return_type==0 || $return_type>=4) && $remainder_seconds-$years*31536000-$monthes*2592000-86400>0){$days = floor(($remainder_seconds-$years*31536000-$monthes*2592000)/(86400));}//时$hours = 0;if(($return_type==0 || $return_type>=3) && $remainder_seconds-$years*31536000-$monthes*2592000-$days*86400-3600>0){$hours = floor(($remainder_seconds-$years*31536000-$monthes*2592000-$days*86400)/3600);}//分$minutes = 0;if(($return_type==0 || $return_type>=2) && $remainder_seconds-$years*31536000-$monthes*2592000-$days*86400-$hours*3600-60>0){$minutes = floor(($remainder_seconds-$years*31536000-$monthes*2592000-$days*86400-$hours*3600)/60);}//秒$seconds = $remainder_seconds-$years*31536000-$monthes*2592000-$days*86400-$hours*3600-$minutes*60;$return = false;switch ($return_type){case 0:if($years>0){$return = $years.$format_array[0].$monthes.$format_array[1].$days.$format_array[2].$hours.$format_array[3].$minutes.$format_array[4].$seconds.$format_array[5];}else if($monthes>0){$return = $monthes.$format_array[1].$days.$format_array[2].$hours.$format_array[3].$minutes.$format_array[4].$seconds.$format_array[5];}else if($days>0){$return = $days.$format_array[2].$hours.$format_array[3].$minutes.$format_array[4].$seconds.$format_array[5];}else if($hours>0){$return = $hours.$format_array[3].$minutes.$format_array[4].$seconds.$format_array[5];}else if($minutes>0){$return = $minutes.$format_array[4].$seconds.$format_array[5];}else{$return = $seconds.$format_array[5];}break; case 1:$return = $seconds.$format_array[5];break;case 2:$return = $minutes.$format_array[4].$seconds.$format_array[5];break;case 3:$return = $hours.$format_array[3].$minutes.$format_array[4].$seconds.$format_array[5];break;case 4:$return = $days.$format_array[2].$hours.$format_array[3].$minutes.$format_array[4].$seconds.$format_array[5];break;case 5:$return = $monthes.$format_array[1].$days.$format_array[2].$hours.$format_array[3].$minutes.$format_array[4].$seconds.$format_array[5];break;case 6:$return = $years.$format_array[0].$monthes.$format_array[1].$days.$format_array[2].$hours.$format_array[3].$minutes.$format_array[4].$seconds.$format_array[5];break;default:$return = false; }return $return;}?
