# swoole_buffer->substr
從緩沖區中取出內容。
```php
string swoole_buffer->substr(int $offset, int $length = -1, bool $remove = false);
```
* `$offset` 表示偏移量，如果為負數，表示倒數計算偏移量
* `$length` 表示讀取數據的長度，默認為從 $offset 到整個緩存區末尾
* `$remove` 表示從緩沖區的頭部將此數據移除。只有 $offset = 0 時此參數才有效
> `swoole_buffer->substr()` 會復制一次內存
> `$remove` 后內存并沒有釋放，只是底層進行了指針偏移。當銷毀此對象時才會真正釋放內存
> `1.9.4`及之后的版本里，`swoole_buffer->substr()` 能夠在某些情況下觸發 `swoole_buffer->recycle()`
