Membangun dan memodifikasi string

 use ChromaXStringBuilderStringBuilder;

$builder = new StringBuilder('rolod muspi meroL');
$builder
	->reverse()
	->append(' sit amet, consetetur')
	->append(12)
	->append(false)
	->prepend('b')
	->append(true)
	->insert(1, 'qäs')
	->replace(6, 2, 'wertz')
	->setCharAt(4, '2')
	->delete(0, 2)
	->delete(40)
	->deleteCharAt(3);

$result = $builder->build();
fwrite(STDOUT, ' 1. Built string                                          ' . $result . PHP_EOL);

$result = $builder->buildSubstring(5, 2);
fwrite(STDOUT, ' 2. Built substring                                       ' . $result . PHP_EOL);

$result = $builder->buildSubstring(5);
fwrite(STDOUT, ' 3. Built substring                                       ' . $result . PHP_EOL);

$result = $builder->charAt(5);
fwrite(STDOUT, ' 4. Character at position 5                               ' . $result . PHP_EOL);

$result = $builder->firstChar();
fwrite(STDOUT, ' 5. First character                                       ' . $result . PHP_EOL);

$result = $builder->lastChar();
fwrite(STDOUT, ' 6. Last character                                        ' . $result . PHP_EOL);

akan menampilkan yang berikut ini

 1. Built string                                          ä2wertzem ipsum dolor sit amet, conset
 2. Built substring                                       rt
 3. Built substring                                       rtzem ipsum dolor sit amet, conset
 4. Character at position 5                               r
 5. First character                                       ä
 6. Last character                                        t

Mendapatkan properti string

 $result = $builder->length();
fwrite(STDOUT, ' 7. String length                                         ' . $result . PHP_EOL);

$result = $builder->size();
fwrite(STDOUT, ' 8. Number of bytes                                       ' . $result . PHP_EOL);

$result = $builder->indexOf('e');
fwrite(STDOUT, ' 9. First occurence of "e"                                ' . $result . PHP_EOL);

$result = $builder->indexOf('e', 5);
fwrite(STDOUT, '10. First occurence of "e" after position 5               ' . $result . PHP_EOL);

$result = $builder->lastIndexOf('e');
fwrite(STDOUT, '11. Last occurence of "e"                                 ' . $result . PHP_EOL);

$result = $builder->lastIndexOf('e', 5);
fwrite(STDOUT, '12. Last occurence of "e" before the 5th last character   ' . $result . PHP_EOL);

$result = $builder->contains('ipsum');
fwrite(STDOUT, '13. Whether the string contains "ipsum"                   ' . $result . PHP_EOL);

akan menampilkan yang berikut ini

 7. String length                                         38
 8. Number of bytes                                       39
 9. First occurence of "e"                                4
10. First occurence of "e" after position 5               8
11. Last occurence of "e"                                 37
12. Last occurence of "e" before the 5th last character   29
13. Whether the string contains "ipsum"                   <TRUE>

Penanganan pengecualian

Semua metode menampilkan InvalidArgumentException jika salah dikonfigurasi kecuali indexOf dan lastIndexOf yang mengembalikan null jika subtring yang diberikan tidak ditampung oleh string yang akan dibuat.

 use ChromaXStringBuilderStringBuilder;

try {
	$builder = new StringBuilder();

	$result = $builder->indexOf('a');
	fwrite(STDOUT, '1. Result                 ' . $result . PHP_EOL);

	$result = $builder->lastIndexOf('a');
	fwrite(STDOUT, '2. Result                 ' . $result . PHP_EOL);

	$result = $builder->charAt(10);
	fwrite(STDOUT, '3. Result                 ' . $result . PHP_EOL);

} catch (InvalidArgumentException $exception) {
	fwrite(STDERR, 'Exception with message    ' . $exception->getMessage() . PHP_EOL);
}

akan menampilkan yang berikut ini

 1. Result                 <NULL>
2. Result                 <NULL>
Exception with message    Position invalid
