IntlChar::getNumericValue — Get the numeric value for a Unicode code point
Gets the numeric value for a Unicode code point as defined in the Unicode Character Database.
For characters without any numeric values in the Unicode Character Database, this function will return
IntlChar::NO_NUMERIC_VALUE
.
Numeric value of codepoint
,
or IntlChar::NO_NUMERIC_VALUE
if none is defined. This
constant was added in PHP 7.0.6, prior to this version the literal value
(float)-123456789
may be used instead. Returns null
on failure.
Example #1 Testing different code points
<?php
var_dump(IntlChar::getNumericValue("4"));
var_dump(IntlChar::getNumericValue("x"));
var_dump(IntlChar::getNumericValue("\u{216C}"));
?>
The above example will output:
float(4) float(-123456789) float(50)
