Modified files:

/php-src/ext/standard php_string.h string.c
Log:
MFH: explode() stuff:
- Fixed bug #47560 (explode()'s limit parameter odd behaviour) by reverting
change for bug #47546
- Changed int to long where needed (should fix memory errors from overflow
seen in bug #47854)
- Simplified logic a bit with limit and its default value
- php_explode_negative_limit(): removed safe_emalloc (not needed; plain
erealloc is used later)
- Moved declarations/allocation to optimize if the delimiter isn't found
- Changed ALLOC_STEP size for less realloc's (and maybe better memory block
alignment?)
