API Documentation

PersianConverterBuilder Class

The PersianConverterBuilder class provides a fluent interface to create a PersianConverter with customizable strategies for text normalization and number conversion.

Methods

• static create(): self

  • Creates and returns a new instance of the builder.

  • Example:

    $builder = PersianConverterBuilder::create();

• withNumberConversion(bool $keepEnglishNumbers = false): self

  • Enables number conversion. By default, converts English and Arabic numbers to Persian numbers.

  • Parameters:

    • bool $keepEnglishNumbers (default: false): Whether to keep English numbers.

    • If $keepEnglishNumbers is true, only Arabic numbers are converted.

  • Example:

    $builder->withNumberConversion(true);

• withTextNormalization(bool $keepPersianDiacritic = true): self

  • Enables text normalization. Optionally keeps Persian diacritics.

  • Parameters:

    • bool $keepPersianDiacritic (default: true): Whether to keep Persian diacritics.

  • Example:

    $builder->withTextNormalization(false);

• build(): PersianConverter

  • Builds and returns a PersianConverter instance with the configured strategies.

  • Throws:

    • MissingStrategyException If no strategies are enabled, i.e., both text normalization and number conversion are disabled.

  • Example:

    $converter = $builder->build();

PersianConverter Class

The PersianConverter class applies various conversion strategies to normalize Persian text and convert numbers.

Methods

• static createDefault(): self

  • Creates a default PersianConverter with text normalization and Persian number conversion enabled.

  • Example:

    $converter = PersianConverter::createDefault();

• convert(string $input): string

  • Applies all strategies to the input string and returns the converted text.

  • Throws:

    • TextConversionException on conversion failure.

  • Example:

    $convertedText = $converter->convert("متن فارسی 123");

PersianTextService Class

The PersianTextService class provides utility methods for text normalization using PersianConverter with various configurations.

Methods

• static normalize(string $input): string
  Normalizes the text with default settings (text normalization and Persian number conversion).

  • Example:

    $normalizedText = PersianTextService::normalize("متن فارسی 123");

• static normalizeTextWithEnglishNumbers(string $input): string

  • Normalizes the text while keeping English numbers.

  • Example:

    $normalizedText = PersianTextService::normalizeTextWithEnglishNumbers("متن فارسی 123");

• static normalizeTextWithoutNumbers(string $input): string

  • Normalizes the text without converting numbers.

  • Example:

    $normalizedText = PersianTextService::normalizeTextWithoutNumbers("متن فارسی 123");

Examples

1. Simple Text Normalization

   echo PersianTextService::normalize("𞸮ﻼم 123 يوﺱ𞺰");
   // Outputs: "سلام ۱۲۳ یوسف"

2. Normalization with English Numbers

   echo PersianTextService::normalizeTextWithEnglishNumbers("𞸮ﻼم 123 يوﺱ𞺰");
   // Outputs: "سلام 123 یوسف"

3. Normalization without Number Conversion

   echo PersianTextService::normalizeTextWithoutNumbers("𞸮ﻼم 123 يوﺱ𞺰");
   // Outputs: "سلام 123 یوسف"

4. Custom Converter: Combining Multiple Conversions

   The library allows chaining multiple conversion rules in one go:

   $converter = PersianConverterBuilder::create()
       ->withTextNormalization(false)
       ->withNumberConversion()
       ->build();
   echo $converter->convert("𞸮ﻼم 123 يوﺱ𞺰");
   // Outputs: "سلام ۱۲۳ یوسف"

5. Removing Diacritics

   You can also remove diacritics from Persian text using the following approach:

   $converter = PersianConverterBuilder::create()
       ->withTextNormalization(keepPersianDiacritic: false)
       ->build();
   
   $input = "حَتماً";
   echo $converter->convert($input);
   // Outputs: حتما
