篇首语：盛年不重来，一日难再晨。及时宜自勉，岁月不待人。本文由小常识网(cha138.com)小编为大家整理，主要介绍了知识大全实测在class的function中include的文件中非php的global全局环境相关的知识，希望对你有一定的参考价值。

正如标题所言经测试的结果为在class中include后被include文件变量域已经变成func中了非全局但是可以通过global提升感兴趣的朋友可以参考下哈希望对大家有所帮助

　　测试代码 php

复制代码代码如下: <?php $g = g ; class c function fun() include( php ); echo "n in class fun n"; global $g ; var_dump("$g => " $g $g => $g $gg => $gg ); echo "n n"; c::fun(); echo "n in php n"; var_dump( $g => $g $g => $g $gg => $gg ); echo "n n";

　　代码 php

复制代码代码如下: <?php $g = g ; global $gg ;//本环境下并非全局需要提升 $gg = gg ; function g fun() global $g $g $gg ; echo "n in g fun n"; var_dump( $g => $g $g => $g $gg => $gg ); echo "n n"; g fun(); echo "n in php n"; var_dump( $g => $g $g => $g $gg => $gg ); echo "n n"; global $g ; echo "n in php global n"; var_dump( $g => $g $g => $g $gg => $gg ); echo "n n";

　　结果

复制代码代码如下: in g fun string( ) "$g => " string( ) "g " string( ) "$g => " NULL string( ) "$gg => " string( ) "gg " in php string( ) "$g => " NULL string( ) "$g => " string( ) "g " string( ) "$gg => " string( ) "gg " in php global string( ) "$g => " string( ) "g " string( ) "$g => " string( ) "g " string( ) "$gg => " string( ) "gg " in class fun string( ) "$g => " string( ) "g " string( ) "$g => " string( ) "g " string( ) "$gg => " string( ) "gg " in php string( ) "$g => " string( ) "g " string( ) "$g => " NULL string( ) "$gg => " string( ) "gg " cha138/Article/program/PHP/201311/21095
