解決亂碼問題：

連接時 設置編碼：$conn = oci_connect("C##SCOTT", "tiger",$db,'utf8');

綁定數據時候中文轉碼：mb_covert_encoding($data,'GBK','UTF-8');

 

plsql 操作數據庫：

select * from user_constraints where table_name='表名字，必須大寫';                    //通過sql去查詢這個表的約束

select userenv('language') from dual;                         //查看字符集

sql語句select * from V$NLS_PARAMETERS查看本地字符集，查看第一行和第九行是否對應

 

 

 

oci 操作 oracle 數據庫：

public function select(){
    //echo phpinfo();die();
    $conn = oci_connect('scott','Wcs123456','127.0.0.1/orcl');

    if($conn){
        echo "connect success";
        echo '<br>';
    }else{
        echo "connect error";
        echo '<br>';
    }
    $sql = "select * from or_student";
    $ora_test = oci_parse($conn,$sql);  //編譯sql語句
    oci_execute($ora_test,OCI_COMMIT_ON_SUCCESS);  //執行

    //1、第一種
    $rr = oci_fetch_all($ora_test,$r);

    //2、第二種
    //$r = oci_fetch_array($ora_test, OCI_BOTH);

    foreach($r as $rows){
        echo "";echo '<br>';
        foreach($rows as $col_values){
            echo $col_values.'/';
        }
    }
    echo '<br>';echo '<br>';
    var_dump($r);
    //var_dump($rr);

    //釋放資源
    oci_free_statement($ora_test);
    oci_close($conn);
}

public function add1(){
    $conn = oci_connect('scott','Wcs123456','127.0.0.1/orcl');
    $query="insert into or_student(S_ID,S_NAME,S_SEX) values(:S_ID,:S_NAME,:S_SEX)";
    $statement=oci_parse($conn,$query);

    $S_ID='8';
    $S_NAME='qq';
    $S_SEX='';

    oci_bind_by_name($statement,":s_id",$S_ID);
    oci_bind_by_name($statement,":s_name",$S_NAME);
    oci_bind_by_name($statement,":s_sex",$S_SEX);



    //執行語句，設置執行模式為自動提交
    oci_execute($statement,OCI_COMMIT_ON_SUCCESS);
    //檢查影響的行數

    echo "插入成功：".oci_num_rows($statement);


    //釋放資源
    oci_free_statement($statement);
    oci_close($conn);

}

public function add2(){
    $conn = oci_connect('scott','Wcs123456','127.0.0.1/orcl');
    $query="insert into or_student(s_id,s_name,s_sex) values(9,'第七','')";
    $statement=oci_parse($conn,$query);

    //執行語句，設置執行模式為自動提交
    oci_execute($statement,OCI_COMMIT_ON_SUCCESS);
    //檢查影響的行數

    echo "插入成功：".oci_num_rows($statement);

    //釋放資源
    oci_free_statement($statement);
    oci_close($conn);

}



public function delete(){

    $conn = oci_connect('scott','Wcs123456','127.0.0.1/orcl');
    $query="delete from or_student where S_ID=5";
    $statement=oci_parse($conn,$query);


    //執行語句，設置執行模式為自動提交
    oci_execute($statement,OCI_COMMIT_ON_SUCCESS);
    //檢查影響的行數

    echo "刪除成功：".oci_num_rows($statement);


    //釋放資源
    oci_free_statement($statement);
    oci_close($conn);
