PHP安裝後php-config命令幹嘛的

標籤：

php-config 是一個簡單的命令列指令碼用於查看所安裝的 PHP 配置的資訊。

我們在命令列執行 php-config 會輸出所有的配置資訊

Usage: /usr/local/php/bin/php-config [OPTION]Options:  --prefix            [/usr/local/php]  --includes          [-I/usr/local/php/include/php -I/usr/local/php/include/php/main -I/usr/local/php/include/php/TSRM -I/usr/local/php/include/php/Zend -I/usr/local/php/include/php/ext -I/usr/local/php/include/php/ext/date/lib]  --ldflags           [ -L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/lib -L/usr/local/lib -L/usr/local/mysql/lib]  --libs              [  -lz -lresolv -lmysqlclient -lmcrypt -lpng -lz -lcurl -lm  -lxml2 -lz -licucore -lm -lcurl -lxml2 -lz -licucore -lm -lmysqlclient -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm ]  --extension-dir     [/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226]  --include-dir       [/usr/local/php/include/php]  --man-dir           [/usr/local/php/php/man]  --php-binary        [/usr/local/php/bin/php]  --php-sapis         [ cli fpm cgi]  --configure-options [--prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-curl --enable-fpm --with-mcrypt --with-mhash --with-gd -enable-zip --enable-fastCGI --without-iconv]  --version           [5.6.21]  --vernum            [50621]

 

其實php-config只是一個指令碼而已

我們先查一下php-config在哪,然後開啟檔案研究一番

 

where php-configlocalhost% where php-config/usr/local/php/bin/php-config/usr/bin/php-configlocalhost% vim /usr/local/php/bin/php-config

 

指令碼內容如下
