PHP安装VLD查看opcode

# wget /> # tar zxvf vld-0.10.1.tgz
# cd ./vld-0.10.1
# /usr/local/php/bin/phpize              或者直接phpize
# ./configure --with-php-config=/usr/local/php/bin/php-config --enable-vld
# make && make install

---------------------------------

编辑php.ini文件激活vld扩展：

extension=vld.so

 

重启Apache：
# /usr/local/apache2/bin/apachectl restart
--------------------------------- 

至此,VLD就安装完了。写个简单的test.php

<?php $a='123'; echo $a;?>

 

# php -dvld.active=1 ./test.php

如果没有设置php环境变量的话

#/usr/local/php/bin/php  -dvld.active=1  test.php
