编译安装PHP

本文以centos stream 9和php8.1为例，描述编译思路

安装编译需要的工具和依赖

如何确定需要的依赖，看一下你要用的php扩展，需要那些系统组件和组件对应的系统库

可以查看扩展库归类，找到安装/配置说明可以查看详细说明,举例说明 GD库配置参数详细说明

使用dnf或yum install xxx安装

#编译器相关工具
deltarpm gcc gcc-c++ make cmake autoconf bison re2c

#基础库
glibc glibc-devel glib2 glib2-devel

#网络和数据库相关
curl curl-devel libcurl libcurl-devel sqlite-devel sqlite-devel libsqlite3x-devel

#文本字符数据格式
oniguruma oniguruma-devel libxml2 libxml2-devel libxslt libxslt-devel libtidy-devel libtidy libicu-devel

#图片格式 字体
gd-devel
freetype freetype-devel libjpeg libjpeg-devel libjpeg-turbo libjpeg-turbo-devel libpng libpng-devel libtiff-dev libgif-dev libwebp-devel

#文件解压缩
 zlib zlib-devel libzip-devel  bzip2 bzip2-devel

#数学和加密
openssl openssl-devel libmcrypt libmcrypt-devel mhash mhash-devel mcrypt libargon2 libsodium

手动编译安装

有些库没有系统二进制包，不能直接使用命令安装需要下载来，或者版本太低达不到php的要求，需要手动编译安装

libiconv libargon2 libsodium

依赖说明

deltarpm 一种rpm包，优化了体积

bison 是一种通用目的的分析器生成器

re2c 一个将正则表达式转化成基于C语言标识的预处理器

oniguruma 正则表达式库，使用–enable-mbstring需要安装

freetype 可移植的字体引擎，它提供统一的接口来访问多种字体格式文件 –with-freetype

libicu Unicode 支持、软件国际化编码 –enable-intl 开启intl扩展

libxml2 xml操作库 –enable-xml 开启

libxslt 是一种样式转换标记语言，可以将XML资料档转换为另外的XML或其它格式 –with-xsl

libtidy 处理html的一种扩展 –with-tidy 很少用

libiconv 字符编码转换库启用–with-iconv

查看编译选项

./configure --help

创建用户和组

id -g www >/dev/null 2>&1
[ $? -ne 0 ] && groupadd www
id -u www >/dev/null 2>&1
[ $? -ne 0 ] && useradd -g www -M -s /sbin/nologin www

常用的编译参数选项，来自oneinstack脚本，php8.1.sh 安装源码

./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc \
    --with-config-file-scan-dir=/usr/local/php/etc/php.d \
    --with-fpm-user=www --with-fpm-group=www --enable-fpm --disable-fileinfo \
    --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd \
    --with-iconv --with-freetype --with-jpeg --with-zlib \
    --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-exif \
    --enable-sysvsem --with-curl --enable-mbregex \
    --enable-mbstring --with-password-argon2 --with-sodium=/usr/local --enable-gd --with-openssl \
    --with-mhash --enable-pcntl --enable-sockets --enable-ftp --enable-intl --with-xsl \
    --with-gettext --with-zip=/usr/local --enable-soap --disable-debug
#防止libiconv导致的报错
make ZEND_EXTRA_LIBS="-L/usr/local/libiconv/lib/ -liconv"
make install

如上启用了fpm，mysqli，mysqland，iconv，gd，xml，bcmath，shmop，exif，sysvsem，curl，mbstring，Password hashing，mhash，openssl，pcntl，sockets，ftp，intl，xsl，gettext，zip，soap

根据项目实际需求来启用需要的参数，比如，项目用cli框架swoole或者workman之类的可以不启用fpm

PHP debug 笔记

简单方式

修改php错误级别，var_dump(),print_r(),die(),exit() 人工断点。

出现了coredump

数据库迁移文件Phinx

如何刷新所有回滚

不能直接刷新所有回滚，创建完第一个迁移之后，使用断点命令打上断点，方便后边刷新所有回滚，这样只会滚两次就可以了。

phinx breakpoint -e development -t 20120103083322（第一个迁移的时间版本）

数据模拟的库

改用 https://fakerphp.github.io/#installation，原先的过时了。

setInterval轮询问题记录

一个electron项目，在使用setInterval轮询时，出现了网络崩溃的系统错误。在setInterval中执行console.log显示setInterval还会执行，但是axios不会重新发起ajax请求。其中getControlStatus轮询后端接口获取数据

setInterval存在的问题

对自己调用的代码是否报错会无视掉。即自己调用的代码即使错误，也会继续执行下去，这就是导致上述问题获取接口失效原因。

setInterval无视网络延迟
我们在向服务器轮询数据的时候，如果发生网络卡顿的情况，客户端收到请求响应的时间大于interval循环的时间。而setInterval会无视任何情况下继续定时执行，这就会导致了用户的客户端里充斥着客户端的请求

php安装 pear 文档

wget http://pear.php.net/go-pear.phar
#指定php目录安装pear
sudo /usr/local/php/bin/php go-pear.phar

安装之后可以使用pear 和pecl命令安装扩展

方式一使用pear相关命令

PEAR命令安装扩展文档

pear install extension_name
pear upgrade extension_name
pear install --onlyreqdeps html_page2

参数
-onlyreqdeps (install required dependencies (依赖) only) 安装需要依赖
–alldeps (install all dependencies (依赖) ) 安装全部依赖

方式二

pecl命令文档

方式三

phpize源码编译安装 (共享/动态扩展) 以redis为例

上https://pecl.php.net/下载好扩展的源码包 redis-6.2.7.tar.gz

tar -zxvf redis-6.2.7.tar.gz
cd redis-6.2.7
/usr/local/php/bin/phpize 
./configure --with-php-config=/usr/local/php/bin/php-config
make && make install 
#写入配置
 echo 'extension=redis.so' > /usr/local/php/etc/php.d/redis.ini

扩展静态编译到php中

PHP XML操作FAQ

加载h5标签报错

Tag xxx invalid in Entity

$html_dom = new DOMDocument();
//关闭h5标签可能的报错
libxml_use_internal_errors(true);
$html_dom->loadHTML($html5);

DOMDocument 保存 xml时中文出现乱码

$html_dom = new DOMDocument();
$html_dom->loadHTML('<?xml encoding="UTF-8">'.$html);

PHP的DOM内部是utf8机制的,在loadHTML时,是通过检查字符中meta的charset来设置编码的,如果没有charset,就当iso8859进行处理了,而这种情况下进行saveXML时,输出来的却是utf8,所以就看到乱码了.

对不包含<meta>标签和<body>标签的富文本字符串处理特别有用
