Class Phalcon\Db\Index

implements Phalcon\Db\IndexInterface

Source on GitHub

Allows to define indexes to be used on tables. Indexes are a common way to enhance database performance. An index allows the database server to find and retrieve specific rows much faster than it could do without an index

<?php

// Define new unique index
$index_unique = new \Phalcon\Db\Index(
    'column_UNIQUE',
    [
        'column',
        'column'
    ],
    'UNIQUE'
);

// Define new primary index
$index_primary = new \Phalcon\Db\Index(
    'PRIMARY',
    [
        'column'
    ]
);

// Add index to existing table
$connection->addIndex("robots", null, $index_unique);
$connection->addIndex("robots", null, $index_primary);
