'''PHP'''是一個程式語言。

== 安裝 ==

在[[Debian]]下的testing可以直接安裝系統的PHP：

<syntaxhighlight lang="bash">
sudo apt update; sudo apt install -y composer php-apcu php-bcmath php-bz2 php-cli php-curl php-dba php-ds php-fpm php-gd php-gmp php-imagick php-intl php-ldap php-mbstring php-memcache php-memcached php-mysql php-odbc php-opcache php-pcov php-pgsql php-readline php-redis php-snmp php-soap php-sqlite3 php-tidy php-uuid php-xml php-xmlrpc php-xsl php-yaml php-zip; sudo apt clean
</syntaxhighlight>

在[[Ubuntu]]下可以用下面指令安裝ondrej PPA版的PHP，目前在[[Ubuntu]] 24.04下php-decimal編不出來，需要自己先拿掉。

PHP 7.4：

<syntaxhighlight lang="bash">
sudo LC_ALL=C.UTF-8 add-apt-repository -y ppa:ondrej/php; sudo apt update; sudo apt install -y composer php7.4-apcu php7.4-bcmath php7.4-bz2 php7.4-cli php7.4-curl php7.4-dba php7.4-decimal php7.4-ds php7.4-fpm php7.4-gd php7.4-gmp php7.4-imap php7.4-imagick php7.4-inotify php7.4-intl php7.4-json php7.4-ldap php7.4-lz4 php7.4-mbstring php7.4-memcache php7.4-memcached php7.4-mysql php7.4-odbc php7.4-opcache php7.4-pcov php7.4-pgsql php7.4-readline php7.4-redis php7.4-snmp php7.4-soap php7.4-sqlite3 php7.4-tidy php7.4-uuid php7.4-xml php7.4-xmlrpc php7.4-xsl php7.4-yaml php7.4-zip php7.4-zstd; sudo apt clean

</syntaxhighlight>

== 設定 ==

如果要把opcache加大為256MB（預設應該是128MB）：

<syntaxhighlight lang="ini">
[opcache]
opcache.memory_consumption=256
</syntaxhighlight>

== 管理 ==

比較大的專案或是同一台機器跑多個PHP專案時，可能會吃完opcache的cache（預設是128MB），可以考慮安裝[https://github.com/JorgenEvens/php-cache-dashboard php-cache-dashboard]觀察cache的使用率。
