以下是log分析的基类可以自定义扩展。需要实现以下方法

formatData($data, $type)

<?phpabstract class log {    //文本    public $text = '';    //删除的条件含有的内容删除当前条    protected $removeCondition = array();    //删除的数据    public $removeData = array();    //分组条件    protected $group = '';    //分条条件    protected $line = '';    //替换条件 替换为空    protected $replace = array();    //调用formatData表示全局调用    protected $typeAll = 'all';    //调用formatData表示分组调用    protected $typeGroup = 'group';    //需要实现的数据格式化方法    abstract public function formatData($data, $type);    /**     * 设置文本内容     * @param $file 文件地址     * @return $this 自己的指针     */    public function setTextByFiles($files) {        if (is_array($files)) {            foreach ($files as $item) {                $this->text .= file_get_contents($item);            }        } else {            $this->text .= file_get_contents($files);        }        return $this;    }    /**     * 设置段落分割符     * @param $paragraph 分割符     * @return $this 自己的指针     */    public function setGroup($group) {        $this->group = $group;        return $this;    }    /**     * 设置行分割符     * @param $line 分割符     * @return $this 自己的指针     */    public function setLine($line) {        $this->line = $line;        return $this;    }    /**     * 设置替换内容     * @param array|string $replace 内容     * @return $this 自己的指针     */    public function setReplaces($replace) {        $this->replace = $replace;        return $this;    }    /**     * 设置删除行的条件     * @param array $condition 删除行的条件 例array('abc' => '%', 'bcd'=> '=') %表示包含, =表示等于     * @return $this 自己的指针     */    public function setRemoveCondition(array $condition) {        $this->removeCondition = $condition;        return $this;    }    /**     * 运行     */    public function run() {        if (count($this->replace) > 0) {            $this->text = preg_replace($this->replace, '', $this->text);        }        $data = $this->getData();        if ($this->group != '') {            $data = $this->getDataByGroup($data);        }        return $data;    }    /**     * 获取数据     * @return mixed 调用指定方法返回数据     */    protected function getData() {        $data = explode($this->line, $this->text);        return $this->formatData($data, $this->typeAll);    }    /**     * 获取分组数据     * @param $data 数据     * @return array 结果     */    protected function getDataByGroup($data) {        $list = $this->group($data);        foreach ($list as $key => $item) {            $list[$key] = $this->formatData($item, $this->typeGroup);        }        return $list;    }    protected function group($data) {        $list = array();        $j = $i = 0;        foreach ($data as $key => $item) {            $tmp = $this->getLine($item);            if ($tmp != null) {                if (stristr($tmp, $this->group) !== false) {                    $i++;                    $j = 0;                    continue;                }                if (is_numeric($key)) {                    $list[$i][$j] = $tmp;                    $j++;                } else {                    $list[$i][$key] = $tmp;                }            }        }        return $list;    }    /**     * 获取第行数据     * @param $data 数据     * @return null|string 如果符合条件返回null     */    protected function getLine($data) {        $condition = false;        if (count($this->removeCondition) > 0) {            foreach ($this->removeCondition as $key => $item) {                if ($item == '%') {                    if (stristr($data, $key) !== false) {                        $condition = true;                        break;                    }                } else {                    if ($key == trim($data)) {                        $condition = true;                        break;                    }                }            }        }        if ($condition) {            $this->removeData[] = $data;            return null;        }        return trim($data);    }}
