# base_convert should throw a ValueError on characters not valid in number base

**[externals.io](https://daily.dev/sources/externals)** · 1 min read · 0 upvotes · 0 comments

## Summary

A proposal to the PHP internals mailing list suggests that base conversion functions (bindec, octdec, hexdec, base_convert) should throw a ValueError when given characters invalid for the specified number base. Previously these were silently ignored; PHP 7.4 added deprecation notices. The proposal targets PHP 8.6 and is part of the Grouped ValueError Conversions RFC.
