errorCode
is a value that returned by functions: intl_get_error_code(), collator_get_error_code() .
true if it the code indicates some failure, and false

示例 #1 intl_is_failure() example
<?php
function check( $err_code )
{
var_export( intl_is_failure( $err_code ) );
echo "\n";
}
check( U_ZERO_ERROR );
check( U_USING_FALLBACK_WARNING );
check( U_ILLEGAL_ARGUMENT_ERROR );
?>
以上例程的输出类似于：
false false true
