Runtime Configuration
The behaviour of these functions is affected by settings in php.ini.
For further details and definitions of the
INI_* modes, see the
Where a configuration setting may be set.
Here's a short explanation of
the configuration directives.

int
-
PCRE's backtracking limit. Defaults to 100000 for PHP < 5.3.7.
-
pcre.recursion_limit
int
-
PCRE's recursion limit. Please note that if you set this value to a high
number you may consume all the available process stack and eventually
crash PHP (due to reaching the stack size limit imposed by the Operating
System).
-
pcre.jit
bool
-
Whether PCRE's just-in-time compilation is going to be used.
