Here's a short explanation of the configuration directives.

`assert.active` boolean

  Enable assert() evaluation.

`assert.bail` boolean

  Terminate script execution on failed assertions.

`assert.warning` boolean

  Issue a PHP warning for each failed assertion.

`assert.callback` string

  user function to call on failed assertions

`assert.quiet_eval` boolean

  Use the current setting of error_reporting() during assertion expression evaluation. If enabled, no errors are shown (implicit error_reporting(0)) while evaluation. If disabled, errors are shown according to the settings of error_reporting()

`enable_dl` boolean

  This directive is really only useful in the Apache module version of PHP. You can turn dynamic loading of PHP extensions with dl() on and off per virtual server or per directory.

  The main reason for turning dynamic loading off is security. With dynamic loading, it's possible to ignore all open_basedir restrictions. The default is to allow dynamic loading, except when using safe mode. In safe mode, it's always impossible to use dl().

`max_execution_time` integer

  This sets the maximum time in seconds a script is allowed to run before it is terminated by the parser. This helps prevent poorly written scripts from tying up the server. The default setting is 30. When running PHP from the command line the default setting is 0.

  The maximum execution time is not affected by system calls, stream operations etc. Please see the set_time_limit() function for more details.

  You can not change this setting with ini_set() when running in safe mode. The only workaround is to turn off safe mode or by changing the time limit in the php.ini.

  Your web server can have other timeout configurations that may also interrupt PHP execution. Apache has a Timeout directive and IIS has a CGI timeout function. Both default to 300 seconds. See your web server documentation for specific details.

`max_input_time` integer

  This sets the maximum time in seconds a script is allowed to parse input data, like POST and GET. It is measured from the moment of receiving all data on the server to the start of script execution.

`max_input_nesting_level` integer

  Sets the max nesting depth of input variables (i.e. $_GET, $_POST..)

`max_input_vars` integer

  How many input variables may be accepted. Use of this directive mitigates the possibility of denial of service attacks which use hash collisions. If there are more input variables than specified by this directive, an `E_WARNING` is issued, and further input variables are truncated from the request. This limit applies only to each nesting level of a multi-dimensional input array.

`magic_quotes_gpc` boolean
  Aviso

  Esta funcionalidade tornou-se OBSOLETA desde o PHP 5.3.0 e foi REMOVIDA desde o PHP 5.4.0.

  Sets the magic_quotes state for GPC (Get/Post/Cookie) operations. When magic_quotes are on, all ' (single-quote), " (double quote), \ (backslash) and NUL's are escaped with a backslash automatically.

  > Nota:

  > In PHP 4, also $_ENV variables are escaped.

  > Nota:

  > If the magic_quotes_sybase directive is also ON it will completely override magic_quotes_gpc. Having both directives enabled means only single quotes are escaped as ''. Double quotes, backslashes and NUL's will remain untouched and unescaped.

  See also get_magic_quotes_gpc()

`magic_quotes_runtime` boolean
  Aviso

  Esta funcionalidade tornou-se OBSOLETA desde o PHP 5.3.0 e foi REMOVIDA desde o PHP 5.4.0.

  If `magic_quotes_runtime` is enabled, most functions that return data from any sort of external source including databases and text files will have quotes escaped with a backslash. If magic_quotes_sybase is also on, a single-quote is escaped with a single-quote instead of a backslash.

  Functions affected by `magic_quotes_runtime` (does not include functions from PECL):

  - get_meta_tags()
  - file_get_contents()
  - file()
  - fgets()
  - fwrite()
  - fread()
  - fputcsv()
  - stream_socket_recvfrom()
  - exec()
  - system()
  - passthru()
  - stream_get_contents()
  - bzread()
  - gzfile()
  - gzgets()
  - gzwrite()
  - gzread()
  - exif_read_data()
  - dba_insert()
  - dba_replace()
  - dba_fetch()
  - ibase_fetch_row()
  - ibase_fetch_assoc()
  - ibase_fetch_object()
  - mssql_fetch_row()
  - mssql_fetch_object()
  - mssql_fetch_array()
  - mssql_fetch_assoc()
  - mysqli_fetch_row()
  - mysqli_fetch_array()
  - mysqli_fetch_assoc()
  - mysqli_fetch_object()
  - pg_fetch_row()
  - pg_fetch_assoc()
  - pg_fetch_array()
  - pg_fetch_object()
  - pg_fetch_all()
  - pg_select()
  - sybase_fetch_object()
  - sybase_fetch_array()
  - sybase_fetch_assoc()
  - SplFileObject::fgets()
  - SplFileObject::fgetcsv()
  - SplFileObject::fwrite()
`zend.enable_gc` boolean

  Enables or disables the circular reference collector.
