🚀 Quick Start

Basic Usage

Parse an OFX file and access account transactions:

<?php

require 'vendor/autoload.php';

use CihanSenturk\OfxParser\Parser;

// Create parser instance
$parser = new Parser();

// Load OFX file
$ofx = $parser->loadFromFile('/path/to/statement.ofx');

// Or load from string
$ofxContent = file_get_contents('/path/to/statement.ofx');
$ofx = $parser->loadFromString($ofxContent);

// Access bank account
$bankAccount = reset($ofx->bankAccounts);

// Get account information
echo "Account Number: " . $bankAccount->accountNumber . "\n";
echo "Routing Number: " . $bankAccount->routingNumber . "\n";
echo "Account Type: " . $bankAccount->accountType . "\n";
echo "Balance: $" . number_format($bankAccount->balance, 2) . "\n";

// Get statement date range
$statement = $bankAccount->statement;
echo "Statement Period: " . $statement->startDate->format('Y-m-d') . " to " . $statement->endDate->format('Y-m-d') . "\n";

// Loop through transactions
foreach ($statement->transactions as $transaction) {
    echo sprintf(
        "%s | %s | $%s | %s\n",
        $transaction->date->format('Y-m-d'),
        $transaction->type,
        number_format($transaction->amount, 2),
        $transaction->name
    );
}

Working with Multiple Accounts

// Access all bank accounts
foreach ($ofx->bankAccounts as $account) {
    echo "Account: " . $account->accountNumber . "\n";
    echo "Balance: $" . number_format($account->balance, 2) . "\n";
    echo "Transactions: " . count($account->statement->transactions) . "\n\n";
}

Transaction Properties

Each transaction object contains:

$transaction->uniqueId;      // string - Unique transaction ID (FITID)
$transaction->date;          // DateTime - Transaction date
$transaction->amount;        // float - Transaction amount (negative for debits)
$transaction->name;          // string - Transaction description/payee
$transaction->memo;          // string - Additional transaction notes
$transaction->sic;           // string - Standard Industrial Classification code
$transaction->checkNumber;   // string - Check number (if applicable)
$transaction->type;          // string - Transaction type (DEBIT, CREDIT, etc.)

📅 Supported Date Formats

This library automatically detects and parses multiple date formats:

1. YYYYMMDD (OFX Standard)

<DTPOSTED>20231015</DTPOSTED>

2. YYYYMMDDHHMMSS (With Timestamp)

<DTPOSTED>20231015143025</DTPOSTED>

3. MM/DD/YYYY (US Format)

<DTPOSTED>10/15/2023</DTPOSTED>

4. DD/MM/YYYY (European Format)

<DTPOSTED>15/10/2023</DTPOSTED>

5. ISO 8601 (International Standard)

<DTPOSTED>2023-10-15</DTPOSTED>
<DTPOSTED>2023-10-15T14:30:25</DTPOSTED>
<DTPOSTED>2023-10-15T14:30:25Z</DTPOSTED>
<DTPOSTED>2023-10-15T14:30:25+05:00</DTPOSTED>

The parser uses smart detection to differentiate between MM/DD/YYYY and DD/MM/YYYY formats based on which component exceeds 12.

💰 Amount Parsing

Correctly handles all numeric formats:

// Integer amounts (fixed bug: "100" now correctly becomes 100.0, not 1.0)
<TRNAMT>100</TRNAMT>        // → 100.0

// Decimal amounts
<TRNAMT>123.45</TRNAMT>     // → 123.45

// Negative amounts (debits)
<TRNAMT>-50.00</TRNAMT>     // → -50.0

// Large amounts
<TRNAMT>1000000</TRNAMT>    // → 1000000.0

// Zero amounts
<TRNAMT>0</TRNAMT>          // → 0.0

🏦 Bank Account Data Structure

// Bank Account Object
$bankAccount->accountNumber;  // string
$bankAccount->accountType;    // string (CHECKING, SAVINGS, etc.)
$bankAccount->balance;        // float
$bankAccount->balanceDate;    // DateTime
$bankAccount->routingNumber;  // string
$bankAccount->statement;      // Statement object

// Statement Object
$statement->currency;         // string (USD, EUR, etc.)
$statement->startDate;        // DateTime
$statement->endDate;          // DateTime
$statement->transactions;     // array of Transaction objects

📊 Sign-On Response

Access server information:

$signOn = $ofx->signOn;

echo "Server Date: " . $signOn->date->format('Y-m-d H:i:s') . "\n";
echo "Language: " . $signOn->language . "\n";
echo "Institute: " . $signOn->institute . "\n";
echo "Status Code: " . $signOn->status->code . "\n";
echo "Status Severity: " . $signOn->status->severity . "\n";

💼 Investment Account Support

This library supports parsing investment/brokerage account transactions from QFX/OFX files:

Basic Investment Usage

use CihanSenturk\OfxParser\Parsers\Investment;
use CihanSenturk\OfxParser\Entities\Investment as InvEntities;

// Create investment parser
$parser = new Investment();
$ofx = $parser->loadFromFile('/path/to/investment_statement.qfx');

// Loop through investment accounts
foreach ($ofx->bankAccounts as $account) {
    echo "Account: " . $account->accountNumber . "\n";
    
    // Loop through investment transactions
    foreach ($account->statement->transactions as $transaction) {
        $nodeName = $transaction->nodeName;
        
        // Handle different transaction types
        switch ($nodeName) {
            case 'BUYSTOCK':
                echo "Buy Stock: " . $transaction->securityId . "\n";
                echo "Shares: " . $transaction->units . "\n";
                echo "Price: $" . $transaction->unitPrice . "\n";
                echo "Total: $" . abs($transaction->total) . "\n";
                break;
                
            case 'SELLSTOCK':
                echo "Sell Stock: " . $transaction->securityId . "\n";
                break;
                
            case 'INCOME':
                echo "Income: $" . $transaction->total . "\n";
                break;
        }
    }
}

Investment Transaction Types

The parser supports various investment transaction types:

BUYSTOCK - Stock purchase
SELLSTOCK - Stock sale
BUYMF - Mutual fund purchase
SELLMF - Mutual fund sale
REINVEST - Dividend reinvestment
INCOME - Dividend/interest income
INVEXPENSE - Investment expenses

Type-Safe Investment Handling

foreach ($account->statement->transactions as $transaction) {
    // Use instanceof for type-safe handling
    if ($transaction instanceof InvEntities\Transaction\BuyStock) {
        $cusip = $transaction->securityId;
        $shares = $transaction->units;
        $price = $transaction->unitPrice;
        $commission = $transaction->commission;
        // ...
    }
    
    if ($transaction instanceof InvEntities\Transaction\Income) {
        $incomeType = $transaction->incomeType; // DIV, INTEREST, etc.
        $amount = $transaction->total;
        // ...
    }
}

Note: This implementation focuses on transaction data (INVSTMTTRN). Investment positions (INVPOSLIST) and security definitions (SECINFO) are not currently supported but may be added in future versions.

🔒 Security Features

XXE Attack Protection

This library is hardened against XML External Entity (XXE) attacks:

// Automatic protection - no configuration needed
$parser = new Parser();
$ofx = $parser->loadFromFile($filepath); // Safe from XXE attacks

The parser automatically:

Disables external entity loading (libxml_disable_entity_loader(true))
Sets secure XML parsing flags (LIBXML_NOENT | LIBXML_DTDLOAD | LIBXML_DTDATTR)
Prevents malicious XML from accessing server files

Null Safety

All properties use null coalescing operators to prevent null reference errors:

// Safe defaults for missing data
$currency = $statement->currency ?? 'USD';
$language = $signOn->language ?? 'ENG';
$balance = $account->balance ?? 0;

Previous Versions (Legacy)

This package builds upon earlier work by multiple contributors. Version 1.0.0 represents a complete modernization for PHP 8.1+ with breaking changes for improved security and reliability.

⚠️ Breaking Changes from Previous Versions:

Namespace changed from OfxParser\ to CihanSenturk\OfxParser\
Minimum PHP version: 8.1+ (was 5.6+)
PSR-4 autoloading (was PSR-0)
Directory structure: src/ (was lib/OfxParser/)

🔧 Advanced Usage

Custom Date Handling

// Access raw date strings if needed
$transaction->date; // Already parsed as DateTime object

// Format dates as needed
$formattedDate = $transaction->date->format('m/d/Y'); // US format
$formattedDate = $transaction->date->format('d/m/Y'); // EU format
$formattedDate = $transaction->date->format('Y-m-d'); // ISO format

Working with Timezones

// ISO 8601 dates with timezone are automatically handled
$transaction->date->getTimezone(); // Get timezone info

// Convert to different timezone
$utcDate = $transaction->date->setTimezone(new \DateTimeZone('UTC'));
$nyDate = $transaction->date->setTimezone(new \DateTimeZone('America/New_York'));

Filtering Transactions

// Filter by date range
$startDate = new DateTime('2023-01-01');
$endDate = new DateTime('2023-12-31');

$filteredTransactions = array_filter(
    $statement->transactions,
    function($transaction) use ($startDate, $endDate) {
        return $transaction->date >= $startDate && $transaction->date <= $endDate;
    }
);

// Filter by amount
$largeTransactions = array_filter(
    $statement->transactions,
    function($transaction) {
        return abs($transaction->amount) > 1000;
    }
);

// Filter by type
$debits = array_filter(
    $statement->transactions,
    function($transaction) {
        return $transaction->type === 'DEBIT';
    }
);

Calculating Totals

// Calculate total debits
$totalDebits = array_reduce(
    $statement->transactions,
    function($carry, $transaction) {
        return $carry + ($transaction->amount < 0 ? $transaction->amount : 0);
    },
    0
);

// Calculate total credits
$totalCredits = array_reduce(
    $statement->transactions,
    function($carry, $transaction) {
        return $carry + ($transaction->amount > 0 ? $transaction->amount : 0);
    },
    0
);

echo "Total Debits: $" . number_format(abs($totalDebits), 2) . "\n";
echo "Total Credits: $" . number_format($totalCredits, 2) . "\n";
