    SQLiteUnbuffered::fieldName

    (PHP 5 < 5.4.0, PECL sqlite >= 1.0.0)

    sqlite_field_name -- SQLiteResult::fieldName -- SQLiteUnbuffered::fieldName — 特定のフィールドの名前を返す

    説明

    sqlite_field_name ( resource $result , int $field_index ) : string

    オブジェクト指向型 (メソッド):

    SQLiteResult::fieldName ( int $field_index ) : string
    SQLiteUnbuffered::fieldName ( int $field_index ) : string

    Given the ordinal column number, field_index, sqlite_field_name() returns the name of that field in the result set result.

    パラメータ

    result

    SQLite 結果リソース。 このパラメータは、 オブジェクト指向言語型メソッドを使用する場合は不要です。

    field_index

    結果セットにおけるオリジナルのカラム番号

    返り値

    与えられたオリジナルのカラム番号での SQLite 結果セット中のフィールド名を返します。エラーの場合は、FALSE を返します。

    SQLITE_ASSOC および SQLITE_BOTH で 返されるカラム名は、設定オプション sqlite.assoc_case の値に基づき、 大文字小文字が変換されます。

    It's not the most elegant way, but it works:

    <?php
    function sqlite_field_names($db, $tablename){
            $sq5=sqlite_single_query($db, "SELECT sql FROM sqlite_master WHERE tbl_name='".$tablename."'", SQLITE_NUM);
            $kommando=$sq5[0];
            $cut=strtok($kommando,"(");
        while(    $fieldnames[]=strtok(",")) {};
            array_pop($fieldnames);
        foreach(    $fieldnames as $no => $field)
            if (    strpos($field, "PRIMARY KEY")){
                    strtok($field,"(");
                    $primary=strtok(")");
                unset(    $fieldnames[$no]);
            } else
                    $fieldnames[$no]=strtok($field, " ");
        return     $fieldnames;
    }
    ?>

    While working with SQLite using its object-oriented mode, I found need to display a column/field name without knowing what it was in advance.  I couldn't find any examples on the Internet, just this document.  So, for anyone who happens to need to do this, here's an example.

    <?php

    $db     = "db/database.sqlite";

    // create new database (OO interface)
    $dbo = new SQLiteDatabase("$db");

    // create table foo and insert sample data
    $dbo->query("
    CREATE TABLE foo(id INTEGER PRIMARY KEY, name CHAR(255));
    INSERT INTO foo (name) VALUES('Ilia1');
    INSERT INTO foo (name) VALUES('Ilia2');
    INSERT INTO foo (name) VALUES('Ilia3');
    "    );

    $query = "SELECT * FROM foo;";

    $result = $dbo->query($query) or die("Error in query");

    echo     "
    <table border='1' cellpadding='10'>
    <tr>
      <td>"    .$result->fieldName(0)."</td>
      <td>"    .$result->fieldName(1)."</td>
    </tr>"    ;

    // iterate through the retrieved rows
    while ($result->valid()) {
          // fetch current row
          $row = $result->current();
      echo     "
    <tr>
      <td>"    .$row[0]."</td>
      <td>"    .$row[1]."</td>
    </tr>"    ;
          // proceed to next row
          $result->next();
    }

    echo     "</table>";

    ?>

    This code works with SQlite version 3 databases.
    <?php
    function sqlite_field_names($dbfile, $tablename){
        try
          {
            $db = new PDO("sqlite:".$dbfile);
            $sql=$db->query("SELECT sql FROM sqlite_master WHERE tbl_name='".$tablename."'");
        foreach(    $sql as $row)
            {
                $fields = $row["sql"];
            }
            $db = NULL;
       }
       catch(    PDOException $e)
       {
        print     "Exception : ".$e->getMessage();
       }
            $cut=strtok($fields,"(");
        while(    $fieldnames[]=strtok(",")) {};
            array_pop($fieldnames);
        foreach(    $fieldnames as $no => $field)
            if (    strpos($field, "PRIMARY KEY")){
                    strtok($field,"(");
                    $primary=strtok(")");
                unset(    $fieldnames[$no]);
            } else
                    $fieldnames[$no]=strtok($field, " ");
        return     $fieldnames;
    }

    print_r(array_values(sqlite_field_names($dbfile, $tablename)));
    ?>
