By the end of this article, readers will be equipped with the knowledge and tools necessary to implement Persian number conversion in their own projects, ultimately fostering better

Understanding Persian Numbers

Persian numbers, also known as Farsi numbers, are used in Iran and other Persian-speaking regions. They are distinct from Arabic numerals and are written from left to right, similar to English. The Persian numeral system includes the following digits:

  • ۰ (0)
  • ۱ (1)
  • ۲ (2)
  • ۳ (3)
  • ۴ (4)
  • ۵ (5)
  • ۶ (6)
  • ۷ (7)
  • ۸ (8)
  • ۹ (9)

These characters play a crucial role in various applications, including finance, education, and data representation in Persian-speaking countries.

Converting Persian Numbers to English in PHP

To convert Persian numbers to English numerals in PHP, you can create a straightforward function that maps each Persian digit to its corresponding English digit. This function will iterate through the input string, identify Persian digits, and replace them with their English counterparts.

Here is a simple implementation of such a function:

“`php
function persianToEnglish($persianNumber) {
$persianDigits = [‘۰’, ‘۱’, ‘۲’, ‘۳’, ‘۴’, ‘۵’, ‘۶’, ‘۷’, ‘۸’, ‘۹’];
$englishDigits = [‘0’, ‘1’, ‘2’, ‘3’, ‘4’, ‘5’, ‘6’, ‘7’, ‘8’, ‘9’];

return str_replace($persianDigits, $englishDigits, $persianNumber);
}

// Example usage
$persianNumber = “۱۲۳۴۵”;
$englishNumber = persianToEnglish($persianNumber);
echo $englishNumber; // Outputs: 12345
“`

This function utilizes the `str_replace` method to efficiently swap the Persian digits with their English equivalents. When you pass a string containing Persian numbers, it returns the string with the numbers converted to English.

Handling Edge Cases

When converting Persian numbers, consider various edge cases such as:

  • Leading Zeros: Ensure that the conversion maintains any leading zeros.
  • Mixed Content: If the input string contains both Persian numbers and other characters, the function should only convert the numeric portions.
  • Negative Numbers: If you’re dealing with negative numbers, ensure that the negative sign is preserved.

Here’s an enhanced version of the function that checks for these scenarios:

“`php
function persianToEnglishEnhanced($persianNumber) {
$persianDigits = [‘۰’, ‘۱’, ‘۲’, ‘۳’, ‘۴’, ‘۵’, ‘۶’, ‘۷’, ‘۸’, ‘۹’];
$englishDigits = [‘0’, ‘1’, ‘2’, ‘3’, ‘4’, ‘5’, ‘6’, ‘7’, ‘8’, ‘9’];

// Replace Persian digits with English digits
$converted = str_replace($persianDigits, $englishDigits, $persianNumber);

// Handle negative numbers
if (strpos($persianNumber, ‘-‘) !== ) {
return ‘-‘ . ltrim($converted, ‘0’); // Remove leading zeros
}

return ltrim($converted, ‘0’); // Remove leading zeros
}

// Example usage
$persianNumber = “۰۱۲۳۴۵”;
$englishNumber = persianToEnglishEnhanced($persianNumber);
echo $englishNumber; // Outputs: 12345
“`

Additional Considerations

When implementing this conversion in a larger application, consider the following:

  • Localization: Ensure that your application can handle user input in various formats and languages.
  • Validation: Add validation checks to ensure that the input is indeed a valid Persian numeral.
  • Performance: For large datasets or frequent conversions, optimize the function for better performance.

By following these guidelines, you can effectively manage the conversion of Persian numbers to English using PHP in your applications.

Converting Persian Numbers to English in PHP

To convert Persian numbers to English in PHP, you can create a function that maps Persian numeral characters to their English equivalents. The Persian numeral system uses different characters for digits compared to the Arabic numeral system commonly used in English. Below is a detailed approach to implement this conversion.

Persian Number Mapping

The Persian numeral system corresponds to the following mappings:

Persian Digit English Digit
۰ 0
۱ 1
۲ 2
۳ 3
۴ 4
۵ 5
۶ 6
۷ 7
۸ 8
۹ 9

PHP Function for Conversion

You can create a PHP function that utilizes the above mapping to convert a string of Persian numbers to English. Here’s a sample implementation:

“`php
function persianToEnglish($persianNumber) {
$persianDigits = [‘۰’, ‘۱’, ‘۲’, ‘۳’, ‘۴’, ‘۵’, ‘۶’, ‘۷’, ‘۸’, ‘۹’];
$englishDigits = [‘0’, ‘1’, ‘2’, ‘3’, ‘4’, ‘5’, ‘6’, ‘7’, ‘8’, ‘9’];

// Replace Persian digits with English digits
return str_replace($persianDigits, $englishDigits, $persianNumber);
}

// Example usage
$persianNumber = ‘۱۲۳۴۵۶’;
$englishNumber = persianToEnglish($persianNumber);
echo $englishNumber; // Outputs: 123456
“`

Handling Edge Cases

When converting numbers, consider the following edge cases:

  • Empty Strings: Ensure the function handles empty input gracefully.
  • Non-Numeric Characters: Decide how to handle strings that include non-numeric Persian characters.
  • Whitespace: Trim leading and trailing whitespace to avoid conversion issues.

You can enhance the function to address these cases by adding validation:

“`php
function persianToEnglish($persianNumber) {
if (empty($persianNumber)) {
return ”;
}

$persianDigits = [‘۰’, ‘۱’, ‘۲’, ‘۳’, ‘۴’, ‘۵’, ‘۶’, ‘۷’, ‘۸’, ‘۹’];
$englishDigits = [‘0’, ‘1’, ‘2’, ‘3’, ‘4’, ‘5’, ‘6’, ‘7’, ‘8’, ‘9’];

// Replace Persian digits with English digits
$converted = str_replace($persianDigits, $englishDigits, $persianNumber);

// Remove any non-numeric characters
return preg_replace(‘/\D/’, ”, $converted);
}
“`

Testing the Function

It is crucial to test the function with various inputs to ensure reliability. Here are some test cases:

“`php
$testCases = [
‘۱۲۳’ => ‘123’,
‘۴۵۶’ => ‘456’,
‘۱۲۳۴۵۶۷۸۹۰’ => ‘1234567890’,
‘سلام ۱۲۳’ => ‘123’, // Non-numeric characters included
” => ”, // Empty case
];

foreach ($testCases as $persian => $expected) {
$result = persianToEnglish($persian);
echo “Input: $persian | Expected: $expected | Result: $result\n”;
}
“`

This testing setup will ensure that your conversion function performs as expected across a variety of scenarios.
