IntlChar::getPropertyEnum — Get the property constant value for a given property name

### 说明

public static function IntlChar::getPropertyEnum(string `$alias`): int

Returns the property constant value for a given property name, as specified in the Unicode database file PropertyAliases.txt. Short, long, and any other variants are recognized.

In addition, this function maps the synthetic names "gcm" / "General_Category_Mask" to the property `IntlChar::PROPERTY_GENERAL_CATEGORY_MASK`. These names are not in PropertyAliases.txt.

This function complements IntlChar::getPropertyName().

### 参数

`alias`

  The property name to be matched. The name is compared using "loose matching" as described in PropertyAliases.txt.

### 返回值

Returns an `IntlChar::PROPERTY_` constant value, or `IntlChar::PROPERTY_INVALID_CODE` if the given name does not match any property.

### 示例

示例 #1 Testing different properties

    <?php
    var_dump(IntlChar::getPropertyEnum('Bidi_Class') === IntlChar::PROPERTY_BIDI_CLASS);
    var_dump(IntlChar::getPropertyEnum('script') === IntlChar::PROPERTY_SCRIPT);
    var_dump(IntlChar::getPropertyEnum('IDEOGRAPHIC') === IntlChar::PROPERTY_IDEOGRAPHIC);
    var_dump(IntlChar::getPropertyEnum('Some made-up string') === IntlChar::PROPERTY_INVALID_CODE);
    ?>

以上示例会输出：

    bool(true)
    bool(true)
    bool(true)
    bool(true)
