利用PHP脚本辅助MySQL数据库管理2-表主键表索引

<?php
$dbi = new DbMysql;
$dbi->dbh = 'mysql://root:[email protected]/coffeetest';

$map = array();
$dbi->fetchMap("SHOW TABLES", $map);
$tables = array_keys($map);
for($i=0; $i<count($tables); $i++){
    echo($tables[$i]."\n");
    $sql = "SHOW INDEX FROM ".$tables[$i];
    $list = $dbi->fetchAll($sql);
    $indexs = array();
    foreach($list as $item){
        $indexs[$item['Key_name']][] = $item['Column_name'];
    }
    foreach($indexs as $key=>$val){
        echo("\t".$key."\t".implode(",",$val)."\n");
    }
}
