今日应开发需求,想要显示图片的属性信息,于是度娘就告知exif模块可以实现,操作步骤与问题总结吐下;
一、环境介绍
[root@ghzz ~]# cat /etc/redhat-release
CentOS release 6.5 (Final)
You have new mail in /var/spool/mail/root
[root@ghzz ~]# php -v
Zend Guard Loader requires Zend Engine API version 220121212.
The Zend Engine API version 220131226 which is installed, is newer.
Contact Zend Technologies at http://www.zend.com/ for a later version of Zend Guard Loader.
PHP 5.6.14 (cli) (built: Jul 7 2016 12:43:11)
Copyright (c) 1997-2015 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies
with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2015, by Zend Technologies
二、查找模块
方法一:去php安装路径下ext目录下都是模块
cd /root/software/php-5.6.14/ext/exif
###这个模块,应该是php安装包内自带的,但是./configure编译安装的时候没有加载的包
方法二:php官网
三、编译安装 (加载模块)
1)进入php存储模块目录
[root@ghzz lsolesen-pel-56d1b7f]# cd /root/software/php-5.6.14/ext/exif
[root@ghzz exif]# ll
总用量 196
-rw-r--r-- 1 1000 1000 333 9月 30 2015 config.m4
-rw-r--r-- 1 1000 1000 308 9月 30 2015 config.w32
-rw-r--r-- 1 1000 1000 36 9月 30 2015 CREDITS
-rw-r--r-- 1 1000 1000 496 9月 30 2015 example.php
-rw-r--r-- 1 1000 1000 145331 9月 30 2015 exif.c
-rw-r--r-- 1 1000 1000 4933 9月 30 2015 exif.dsp
-rw-r--r-- 1 1000 1000 1953 9月 30 2015 package.xml
-rw-r--r-- 1 1000 1000 1463 9月 30 2015 php_exif.h
-rw-r--r-- 1 1000 1000 29 9月 30 2015 test.php
drwxr-xr-x 2 1000 1000 4096 9月 30 2015 tests
-rw-r--r-- 1 1000 1000 11232 9月 30 2015 test.txt
2)使用phpize添加php动态模块
作用:使用phpize生成
[root@ghzz exif]# /usr/local/php/bin/phpize
Configuring for:
PHP Api Version: 20131106
Zend Module Api No: 20131226
Zend Extension Api No: 220131226
[root@ghzz exif]# ./configure -with-php-config=/usr/local/php/bin/php-config
checking for grep that handles long lines and -e... /bin/grep
#。。。省略若干字段
checking whether stripping libraries is possible... yes
checking if libtool supports shared libraries... yes
checking whether to build shared libraries... yes
checking whether to build static libraries... no
creating libtool
appending configuration tag "CXX" to libtool
configure: creating ./config.status
config.status: creating config.h
[root@ghzz exif]# make && make install
/bin/sh /root/software/php-5.6.14/ext/exif/libtool --mode=compile cc -I. -I/root/software/php-5.6.14/ext/exif -DPHP_ATOM_INC -I/root/software/php-5.6.14/ext/exif/include -I/root/software/php-5.6.14/ext/exif/main -I/root/software/php-5.6.14/ext/exif -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 -DHAVE_CONFIG_H -g -O2 -c /root/software/php-5.6.14/ext/exif/exif.c -o exif.lo
mkdir .libs
cc -I. -I/root/software/php-5.6.14/ext/exif -DPHP_ATOM_INC -I/root/software/php-5.6.14/ext/exif/include -I/root/software/php-5.6.14/ext/exif/main -I/root/software/php-5.6.14/ext/exif -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 -DHAVE_CONFIG_H -g -O2 -c /root/software/php-5.6.14/ext/exif/exif.c -fPIC -DPIC -o .libs/exif.o
/bin/sh /root/software/php-5.6.14/ext/exif/libtool --mode=link cc -DPHP_ATOM_INC -I/root/software/php-5.6.14/ext/exif/include -I/root/software/php-5.6.14/ext/exif/main -I/root/software/php-5.6.14/ext/exif -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 -DHAVE_CONFIG_H -g -O2 -o exif.la -export-dynamic -avoid-version -prefer-pic -module -rpath /root/software/php-5.6.14/ext/exif/modules exif.lo
cc -shared .libs/exif.o -Wl,-soname -Wl,exif.so -o .libs/exif.so
creating exif.la
(cd .libs && rm -f exif.la && ln -s ../exif.la exif.la)
/bin/sh /root/software/php-5.6.14/ext/exif/libtool --mode=install cp ./exif.la /root/software/php-5.6.14/ext/exif/modules
cp ./.libs/exif.so /root/software/php-5.6.14/ext/exif/modules/exif.so
cp ./.libs/exif.lai /root/software/php-5.6.14/ext/exif/modules/exif.la
PATH="$PATH:/sbin" ldconfig -n /root/software/php-5.6.14/ext/exif/modules
----------------------------------------------------------------------
Libraries have been installed in:
/root/software/php-5.6.14/ext/exif/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
Build complete.
Don't forget to run 'make test'.
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/
[root@ghzz exif]# vi /usr/local/php/etc/php.ini
查找:extension = 再最后一个extension= 后面添加上extension = “exif.so”
[root@ghzz ext]# grep -n "exif.so" /usr/local/php/etc/php.ini
743:extension = "exif.so"
[root@ghzz exif]# /etc/init.d/php-fpm restart ##重启加载php模块
四、检查模块运行情况及效果
[root@ghzz ext]# php -m|grep exif
exif
