A class to make it very easy to deal with database connections.

This is version 4 that has many modern programming practices in which will break users of version 3.

Version 3 broke version 2.1.7 in one major way, it required PHP 5.6. Which drop mysql extension support, other than that, nothing as far using the library was changed, only additional features.

This library has an Database class, an combination of the Factory pattern with an Dependency Injection container hosting. This library now is following many OOP principles, one in which, the methods properties public access has been removed. This library also following PSR-2, PSR-4, PSR-11 conventions, and mostly PSR-1, that's still an work in progress.

  • More Todo...

For an full overview see documentation Wiki, which is not completely finish.

Installation

composer require ezsql/ezsql

Usage

require 'vendor/autoload.php';

// **** is one of mysqli, pgsql, sqlsrv, sqlite3, or Pdo.
use ezsql\Database;

$db = Database::initialize('****', [$dsn_path_user, $password, $database, $other_settings], $optional_tag);

// Is same as:
use ezsql\Config;
use ezsql\Database\ez_****;

$setting = new Config('****', [$dsn_path_user, $password, $database, $other_settings]);

$db = new ez_****($settings);

This library will assume the developer is using some sort of IDE with intellisense enabled. The comments/doc-block area will hold any missing documentations. For additional examples see phpunit tests, The tests are fully functional integration tests, meaning the are live database tests, no mocks.

The following has been added since version 2.1.7.

General Methods

to_string($arrays, $separation = ',');
clean($string);
create_cache(string $path = null);
secureSetup(string $key = 'certificate.key',
    string $cert = 'certificate.crt',
    string $ca = 'cacert.pem',
    string $path = '.'._DS
);
secureReset();
createCertificate(string $privatekeyFile = certificate.key,
    string $certificateFile = certificate.crt,
    string $signingFile = certificate.csr,
    string $ssl_path = null, array $details = [commonName => localhost]
);

Shortcut Table Methods

create(string $table = null, ...$schemas);// $schemas requires... column()
column(string $column = null, string $type = null, ...$args);
primary(string $primaryName, ...$primaryKeys);
index(string $indexName, ...$indexKeys);
drop(string $table);

Example

// Creates an database table
create('profile',
    // and with database column name, datatype
    // data types are global CONSTANTS
    // SEQUENCE|AUTO is placeholder tag, to be replaced with the proper SQL drivers auto number sequencer word.
    column('id', INTR, 11, AUTO, PRIMARY), // mysqli
    column('name', VARCHAR, 50, notNULL),
    column('email', CHAR, 25, NULLS),
    column('phone', TINYINT)
);
innerJoin(string $leftTable = null, string $rightTable = null,
    string $leftColumn = null, string $rightColumn = null, string $tableAs = null, $condition = EQ);

leftJoin(string $leftTable = null, string $rightTable = null,
    string $leftColumn = null, string $rightColumn = null, string $tableAs = null, $condition = EQ);

rightJoin(string $leftTable = null, string $rightTable = null,
    string $leftColumn = null, string $rightColumn = null, string $tableAs = null, $condition = EQ);

fullJoin(string $leftTable = null, string $rightTable = null,
    string $leftColumn = null, string $rightColumn = null, string $tableAs = null, $condition = EQ);
prepareOn(); // When activated will use prepare statements for all shortcut SQL Methods calls.
prepareOff(); // When off shortcut SQL Methods calls will use vendors escape routine instead. This is the default behavior.

Shortcut SQL Methods

  • having(...$having);
  • groupBy($groupBy);
  • union(string $table = null, $columnFields = '*', ...$conditions);
  • unionAll(string $table = null, $columnFields = '*', ...$conditions);
  • orderBy($orderBy, $order);
  • limit($numberOf, $offset = null)
  • where( ...$whereConditions);
  • selecting(string $table = null, $columnFields = '*', ...$conditions);
  • create_select(string $newTable, $fromColumns, $oldTable = null, ...$conditions);
  • select_into(string $newTable, $fromColumns, $oldTable = null, ...$conditions);
  • update(string $table = null, $keyAndValue, ...$whereConditions);
  • delete(string $table = null, ...$whereConditions);
  • replace(string $table = null, $keyAndValue);
  • insert(string $table = null, $keyAndValue);
  • insert_select(string $toTable = null, $toColumns = '*', $fromTable = null, $fromColumns = '*', ...$conditions);
// The variadic ...$whereConditions, and ...$conditions parameters,
//  represent the following global functions.
// They are comparison expressions returning an array with the given arguments,
//  the last arguments of _AND, _OR, _NOT, _andNOT will combine expressions
eq('column', $value, _AND), // combine next expression
neq('column', $value, _OR), // will combine next expression again
ne('column', $value), // the default is _AND so will combine next expression
lt('column', $value)
lte('column', $value)
gt('column', $value)
gte('column', $value)
isNull('column')
isNotNull('column')
like('column', '_%?')
notLike('column', '_%?')
in('column', ...$value)
notIn('column', ...$value)
between('column', $value, $value2)
notBetween('column', $value, $value2)
// The above should be used within the where( ...$whereConditions) clause
// $value will protected by either using escape or prepare statement
// To allow simple grouping of basic $whereConditions,
// wrap the following around a group of the above comparison
// expressions within the where( ...$whereConditions) clause
grouping( eq(key, value, combiner ), eq(key, value, combiner ) )
// The above will wrap beginning and end grouping in a where statement
// where required to break down your where clause.
// Supply the the whole query string, and placing '?' within
// With the same number of arguments in an array.
// It will determine arguments type, execute, and return results.
query_prepared(string $query_string, array $param_array);
// Will need to call to get last successful query result, will return an object array
queryResult();

Example for using prepare statements indirectly, with above shortcut SQL methods

// To get all shortcut SQL methods calls to use prepare statements
$db->prepareOn(); // This needs to be called at least once at instance creation

$values = [];
$values['name'] = $user;
$values['email'] = $address;
$values['phone'] = $number;
$db->insert('profile', $values);
$db->insert('profile', ['name' => 'john john', 'email' => 'john@email', 'phone' => 123456]);

// returns result set given the table name, column fields, and ...conditions
$result = $db->selecting('profile', 'phone', eq('email', $email), between('id', 1, $values));

foreach ($result as $row) {
    echo $row->phone;
}

$result = $db->selecting('profile', 'name, email',
    // Conditionals can also be called, stacked with other functions like:
    //  innerJoin(), leftJoin(), rightJoin(), fullJoin()
    //      as (leftTable, rightTable, leftColumn, rightColumn, tableAs, equal condition),
    //  where( eq( columns, values, _AND ), like( columns, _d ) ),
    //  groupBy( columns ),
    //  having( between( columns, values1, values2 ) ),
    //  orderBy( columns, desc ),
    //  limit( numberOfRecords, offset ),
    //  union(table, columnFields, conditions),
    //  unionAll(table, columnFields, conditions)
    $db->where( eq('phone', $number, _OR), neq('id', 5) ),
    //  another way: where( array(key, operator, value, combine, combineShifted) );
    //  or as strings double spaced: where( "key  operator  value  combine  combineShifted" );
    $db->orderBy('name'),
    $db->limit(1)
);

foreach ($result as $row) {
    echo $row->name.' '.$row->email;
}

Example for using prepare statements directly, no shortcut SQL methods used

$db->query_prepared('INSERT INTO profile( name, email, phone) VALUES( ?, ?, ? );', [$user, $address, $number]);

$db->query_prepared('SELECT name, email FROM profile WHERE phone = ? OR id != ?', [$number, 5]);
$result = $db->queryResult(); // the last query that has results are stored in `last_result` protected property

foreach ($result as $row) {
    echo $row->name.' '.$row->email;
}
