ob_start???? 打開輸出控制緩沖（要求php開啟緩存，在php配置文件php.ini文件中可以設(shè)置 output_buffering = on）

ob_get_contents???? 返回輸出緩沖區(qū)內(nèi)容

ob_clean???? 清空（擦掉）輸出緩沖區(qū)

ob_get_clean???? 得到當(dāng)前緩沖區(qū)的內(nèi)容并刪除當(dāng)前輸出緩沖區(qū)

php生成文件的函數(shù) file_put_contents('文件路徑','文件內(nèi)容')。（當(dāng)然php中還有其他寫文件的方法，如fwrite）
