Named typed constants and predicates — give meaning to magic literals.
A raw '', [], '{}', 0, true, or null carries an unstated intent and
gets re-checked defensively all over a codebase (if ($this->delimiter === '')).
These tiny static classes give that intent a name and the check a single home.
use JesseGall\PhpTypes\T_String; $prefix = T_String::empty(); // '' with a name if (T_String::isEmpty($delimiter)) { … } // reads as intent // as a first-class callable $nonEmpty = array_filter($parts, T_String::isNotEmpty(...));
Types
| Class | Constant(s) | Factory | Predicates |
|---|---|---|---|
T_String |
EMPTY, SPACE, NEWLINE, PARAGRAPH, CARRIAGE_RETURN, CRLF, TAB, NULL_BYTE, COMMA, COMMA_SPACE, SLASH, DOT, DASH |
empty() |
isEmpty(), isNotEmpty(), isBlank(), isNotBlank() |
T_Array |
EMPTY, MATRIX |
empty(), matrix() |
isEmpty(), isNotEmpty() |
T_Json |
EMPTY_OBJECT, EMPTY_ARRAY |
emptyObject(), emptyArray() |
isEmptyObject(), isEmptyArray() |
T_Int |
ZERO, ONE, MINUS_ONE |
zero() |
isZero(), isNotZero() |
T_Float |
ZERO |
zero() |
isZero(), isNotZero() |
T_Bool |
TRUE, FALSE |
— | isTrue(), isFalse() |
T_Null |
— | — | isNull(), isNotNull() |
T_Json predicates are semantic — isEmptyObject('{ }') and isEmptyObject("{\n}")
are true (they decode to an empty object), while isEmptyObject('[]') and
invalid JSON are false.
