   再运行php程序时,会出现

  Allowed memory size of 8388608 bytes exhausted (tried to allocate 1298358 bytes)

  出现该错误的原因:在确保不是程序产生的原因(例如死循环),是由于php页面消耗的最大内存默认是为 8M (在PHP的ini件里可以看到) ,

  如果文件太大 或图片太大 在读取的时候 会发生上述错误。

  解决办法:

  1,修改 php.ini将memory_limit由 8M 改成 16M(或更大),重启apache服务

  2,在PHP 文件中 加入 ini_set(‘memory_limit’,‘**M’);注意:为了系统的其它资源的正常使用 请您不要将 memory_limit设置太大,其中-1为不限

  3,修改.htaccess 文档(前提是该目录支持.htaccess)在文档中新增一句:php_value memory_limit 16M(或更大)
