Also affects 7.3 and 7.4 branches. Test script: --------------- <?php $x=json_decode('+123.4'); var_export($x); print("\n"); $x=json_decode('123.4'); var_export($x); print("\n"); Expected result: ---------------- 123.4 123.4 Actual result: -------------- NULL 123.4 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=80678&edit=1
