php基本配置

Jun 23, 2016 pm 01:35 PM

找到php配置文件,查看配置文件路径命令:/usr/local/php/bin/php -i |head

1. 配置disable_function

disable_functions = eval,assert,popen,passthru,escapeshellarg,escapeshellcmd,passthru,exec,system,chroot,scandir,chgrp,chown,escapeshellcmd,escapeshellarg,shell_exec,proc_get_status,ini_alter,ini_restore,dl,pfsockopen,openlog,syslog,readlink,symlink,leak,popepassthru,stream_socket_server,popen,proc_open,proc_close

使用命令可以查看禁止的函数:/usr/local/php/bin/php -i |grep disable_f

出现一个警告,这里我们配置一下时区即可:date.timezone='Asia/Chongqing'


2. 配置error_log

打开php.ini,找到如下选项进行配置

display_errors=off

log_errors=on

error_log=/path/to/logfile

error_reporting = E_ALL & ~E_NOTICE

   

错误级别参考

; E_ALL             所有错误和警告(除E_STRICT外)
; E_ERROR           致命的错误。脚本的执行被暂停。
; E_RECOVERABLE_ERROR    大多数的致命错误。
; E_WARNING         非致命的运行时错误,只是警告,脚本的执行不会停止。
; E_PARSE            编译时解析错误,解析错误应该只由分析器生成。
; E_NOTICE          脚本运行时产生的提醒(往往是我们写的脚本里面的一些bug,比如某个变量没有定义),这个错误不会导致任务中断。
; E_STRICT          脚本运行时产生的提醒信息,会包含一些php抛出的让我们要如何修改的建议信息。
; E_CORE_ERROR      在php启动后发生的致命性错误
; E_CORE_WARNING    在php启动后发生的非致命性错误,也就是警告信息
; E_COMPILE_ERROR    php编译时产生的致命性错误
; E_COMPILE_WARNING  php编译时产生的警告信息
; E_USER_ERROR       用户生成的错误
; E_USER_WARNING    用户生成的警告
; E_USER_NOTICE      用户生成的提醒



3. 配置open_basedir

全局配置:php.ini: open_basedir = /dir1/:/dir2

针对虚拟机配置:httpd-vhost.conf: php_admin_value open_basedir "/dir1/:/dir2/"


4. 安装php的扩展模块(memcache)

memcache在php中编译
#  wget http://www.lishiming.net/data/attachment/forum/memcache-2.2.3.tgz
# tar zxvf memcache-2.2.3.tgz
# cd memcache-2.2.3
# /usr/local/php/bin/phpize
# ./configure --with-php-config=/usr/local/php/bin/php-config
# make
# make install
# cp modules/memcache.so /usr/local/php/ext/   //把memcache.so 拷贝至php的extension_dir下,#查看php extension_dir的方法是  /usr/local/php/bin/php -i |grep extension_dir 
修改扩展路径,在php.ini中修改:
extension_dir = "/usr/local/php/ext"
然后在php.ini 中添加
extension = memcache.so

保存后可以利用 /usr/local/php/bin/php -m  检测和查看具体的参数


memcached 的编译安装
wget http://syslab.comsenz.com/downloads/linux/memcached-1.4.5.tar.gz

tar zxvf memcached-1.2.8.tar.gz
cd  memcached-1.2.8
./configure --prefix=/usr/local/memcached
make && make install

启动:

/usr/local/memcached/bin/memcached -m 2048 -p 11211 -l 127.0.0.1 -d -u www
-m  后边指定memecached使用多少内存,单位是M
-p  指定memcached 启动端口
-l  指定绑定的IP
-u  指定以某个账户的身份启动

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP in Action: Real-World Examples and Applications PHP in Action: Real-World Examples and Applications Apr 14, 2025 am 12:19 AM

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security.

HTTP request methods include GET, POST, PUT and DELETE, which are used to obtain, submit, update and delete resources respectively. 1. The GET method is used to obtain resources and is suitable for read operations. 2. The POST method is used to submit data and is often used to create new resources. 3. The PUT method is used to update resources and is suitable for complete updates. 4. The DELETE method is used to delete resources and is suitable for deletion operations.

Explain the difference between self::, parent::, and static:: in PHP OOP. Explain the difference between self::, parent::, and static:: in PHP OOP. Apr 09, 2025 am 12:04 AM

In PHPOOP, self:: refers to the current class, parent:: refers to the parent class, static:: is used for late static binding. 1.self:: is used for static method and constant calls, but does not support late static binding. 2.parent:: is used for subclasses to call parent class methods, and private methods cannot be accessed. 3.static:: supports late static binding, suitable for inheritance and polymorphism, but may affect the readability of the code.
