1、インストールパッケージをダウンロードしてください
cd ~
wget http://php.net/distributions/php-7.0.1.tar.gz
tar -zxvf php-7.0.1.tar.gz
wget http://php.net/distributions/php-5.6.40.tar.gz
tar -zxvf php-5.6.40.tar.gz
wget http://php.net/distributions/php-7.4.4.tar.gz
tar -zxvf php-7.4.4.tar.gz2、コンパイルしてインストールします
cd ~/php-5.6.40
./configure --prefix=/usr/local/php-5.6.40 --enable-fpm
make
make install
cd ~/php-7.0.1
./configure --prefix=/usr/local/php-7.0.1 --enable-fpm
make
nake install
./configure --prefix=/usr/local/php-7.4.4 --enable-fpm
make
nake install3、テストを開始
ソースディレクトリが提供するテストコードを使用してテストし、ソースツリービューのPHPコードに行く、記事は最終的にテストコードを掲載します。
/usr/local/php-7.4.4/bin/php ~/php-7.0.1/Zend/bench.php
/usr/local/php-7.0.1/bin/php ~/php-7.0.1/Zend/bench.php
/usr/local/php-5.6.40/bin/php ~/php-7.0.1/Zend/bench.php結果は以下の通りであります：
7.4.4：
7.0.1：
5.6.40：
三のギャップ、PHP5実行時間の上側からリフトに関してより明白PHP7を見ることができます。
より詳細なテストコードがソースディレクトリ内のZend / micro_bench.phpでもあります：
7.4.4：
7.0.1：
5.6.40：
4、要約
PHP5に比べPHP7は二倍以上にアップグレードしてください。
