• Are there any Parsing Expression Grammar (PEG) libraries for Javascript or PHP?

  - by Peter J. Wasilko

  I find myself drawn to the Parsing Expression Grammar formalism for describing domain specific languages, but so far the implementation code I've found has been written in languages like Java and Haskell that aren't web server friendly in the shared hosting environment that my organization has to live with. Does anyone know of any PEG libraries or PackRat Parser Generators for Javascript or PHP? Of course code generators in any languages that can produce Javascript or PHP source code would do the trick.

• Variable scope difference between PHP and C: block scope is not exactly the same?

  - by powerboy

  The following PHP code will output 3. function main() { if (1) { $i = 3; } echo $i; } main(); But the following C code will raise a compile error. void main() { if (1) { int i = 3; } printf("%d", i); } So variables in PHP are not strictly block-scoped?

• How important is it to unset variables in PHP?

  - by dd0x

  I am somewhat new to PHP and I am wondering: How important is it to unset variables in PHP? I know in languages like C we free the allocated memory to prevent leaks, etc. By using unset on variables when I am done with them, will this significantly increase performance of my applications? Also is there a benchmark anywhere that compares difference between using unset and not using unset?

• What is faster: write PHP code using "functions" or writing it as pure script?

  - by Ole Jak

  What is faster: writing PHP code using functions or writing it as pure script? So, as I see it Apache or any other server will create from PHP code using functions a pure script... I mean we had: function foo($a, $b){ return ($a + $b); echo foo(4, 5)} and Apache will turn it into something like: echo (5 + 4) Or will it?

• PHP 5 functioning returning an array- interaction without assignment?

  - by Lee

  I'm wondering if this kind of thing will ever be possible in PHP (and whether it already is and I'm just missing something...) <?php function test() { return array( 'id'=>10, 'name'=>'John' ); } echo 'Your name is: '.test()['name']; ?> I'd really like to be able to use returned arrays directly instead of first assigning them to a var... possible?

• how to scan a LAN for live hosts using PHP and SNMP?

  - by aag

  I would like to have a quick script listing all active hosts in a LAN, and I am a bit lost. From other posts I figured that this can be done most effectively by polling the DHCP server (in my case a Lancom router) using SNMP. However, I am not familiar with the SNMP commands in PHP. Is snmpwalk() the correct function? Can I get snmpwalk() or any other php function to return an array that contains a list of all live hosts?

• Is it possible to pass an array as a command line argument to a PHP script?

  - by Manos Dilaverakis

  I'm maintaining a PHP library that is responsible for fetching and storing incoming data (POST, GET, command line arguments, etc). I've just fixed a bug that would not allow it to fetch array variables from POST and GET and I'm wondering whether this is also applicable to the part that deals with the command line. Can you pass an array as a command line argument to PHP?
