首先,推荐如下的设置php内存的方法:
以下两个方法,可以修改php运行时的内存限制。
例如:
query_cache_size=32M
# The number of open tables for all threads. Increasing this value
# increases the number of file descriptors that mysqld requires.
# Therefore you have to make sure to set the amount of open files
# allowed to at least 4096 in the variable "open-files-limit" in
# section [mysqld_safe]
table_cache=256
# Maximum size for internal (in-memory) temporary tables. If a table
# grows larger than this value, it is automatically converted to disk
# based table This limitation is for a single table. There can be many
# of them.
tmp_table_size=5M
另外,再介绍下PHP设置运行时内存大小的方法。
如果在php程序运行时出现如下的错误:
Fatal error: Allowed memory size of 20971520 bytes exhausted (tried to allocate 7325604 bytes) in …(可用的内存为20971520 bytes,尝试分配。。。)
则说明运行时分配的内存不够,此时需要增加支撑php运行的内存了。
解决办法:
一、在php程序里动态分配内存
二、php.ini 中配置
就介绍这些了,记得老板曾说过一句话,我相信你们的技术水平,如果遇到非常难以解决的问题,就适当发挥硬件的优势吧,哈哈,那就加内存,加Cpu,或者上更高配置机器吧。
