IntlChar::getPropertyEnum — Get the property constant value for a given property name
$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().

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

<?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);
