脚本宝典收集整理的这篇文章主要介绍了php – 如何从不同的文件访问函数内的变量？，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
的functions.PHP
<? PHP function connectDB() { $hostname = 'xxxxxxxx'; $db = 'xxxxxxx'; $user = 'xxxxxxxx'; $pass = 'xxxxxxx'; $dbh = new PDO("MysqL:host=$hostname; dbname=$db; charset=utf8",$user,$pass,array(PDO::ATTR_EMULATE_PREPARES => false,PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION)); $sql = "//my query"; $query = $dbh->prepare($sql); $query->execute(array('//value','//value')); $query->setFetchMode(PDO::FETCH_ASSOC); while ($r = $query->fetch()): $VAR1 = $r['column1']; $var2 = $r['column2']; $var3 = $r['column3']; $var4 = $r['column4']; $var5 = $r['column5']; endwhile; } ?>
的index.PHP
<?PHP include 'functions.PHP'; ?> <?PHP try { connectDB(); echo 'You are connected to Database'; echo $var1; $dbh = null; } catch(PDOException $e) { echo $e -> getMessage(); } ?>
方法1
<? PHP $var1 = ''; $var2 = ''; $var3 = ''; $var4 = ''; $var5 = ''; function connectDB() { $hostname = 'xxxxxxxx'; $db = 'xxxxxxx'; $user = 'xxxxxxxx'; $pass = 'xxxxxxx'; $dbh = new PDO("MysqL:host=$hostname; dbname=$db; charset=utf8",'//value')); $query->setFetchMode(PDO::FETCH_ASSOC); while ($r = $query->fetch()): $var1 = $r['column1']; $var2 = $r['column2']; $var3 = $r['column3']; $var4 = $r['column4']; $var5 = $r['column5']; endwhile; } ?>
方法2
<? PHP function connectDB() { $hostname = 'xxxxxxxx'; $db = 'xxxxxxx'; $user = 'xxxxxxxx'; $pass = 'xxxxxxx'; $dbh = new PDO("MysqL:host=$hostname; dbname=$db; charset=utf8",'//value')); $query->setFetchMode(PDO::FETCH_ASSOC); while ($r = $query->fetch()): $GLOBALS['var1'] = $r['column1']; $GLOBALS['var2'] = $r['column2']; $GLOBALS['var3'] = $r['column3']; $GLOBALS['var4'] = $r['column4']; $GLOBALS['var5'] = $r['column5']; endwhile; } ?>
