While the former is usually desirable, the latter can be a security risk if used naively. Starting with PHP 5.2.0, you can allow remote file operations while disallowing the inclusion of remote files in local scripts. In fact, this is the default configuration. </span> </li> <li class="listitem"> <span class="simpara"> <a href="pcre.configuration.html#ini.pcre.backtrack-limit" class="link">pcre.backtrack_limit</a> </span> <span class="simpara"> PCRE's backtracking limit. </span> </li> <li class="listitem"> <span class="simpara"> <a href="pcre.configuration.html#ini.pcre.recursion-limit" class="link">pcre.recursion_limit</a> </span> <span class="simpara"> PCRE's recursion limit.
