php can't execute a perl script via exec -

-

i'm trying execute perl script php. perl script reading webpage , producing xml file data. if exec via shell works expected when i'm trying automate whole thing via php nothing works.

i've tried this:

exec("perl /absolute/path/to/perl/script/parser.pl", $output, $result);

when echo $result variable displays 2. i've switched php safe_mode on , off several times nothing changed. tried set safe_mode_exec_dir without positive results.

when exec simple ls

exec("ls", $output, $result);

everything goes well, list of files , $result 0.

the perl script has chmod 777 not problem of permission. folder has 777.

i'm sure issue server i'm not able find out what.

any appreciated.

thanks

you need specify full path perl executable.

try typing which perl see full path is, place full path in exec call.

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
