Apache/1.3.29 Server at www.faraah.com.sa Port 80

==============================================

this is the .htaccess file that i write

php_value max_execution_time 1200 // seconds
php_value memory_limit 300M // MB
php_value post_max_size 300M // MB
php_value upload_max_filesize 250M // MB

LimitRequestBody 0

i write this file so i can upload more the 300MB

can anyone help me

assuming that comments like // are allowed: did your hoster allow you to change these values via .htaccess?

my hoster won't let me change these values, any attempt to do so results in an internal server error

[ramez_sever]

I think i can because i try to change global variable before

[mrhappiness]

you change which global variable where and before what?

[ramez_sever]

In the past other directory

[mrhappiness]

which variable?

if you change a variable inside a php-script you change it for that very script only

[ramez_sever]

set global_variable off

[mrhappiness]

well, if i were your hoster, i surely would have foreseen such attempts so that this statement wouldn't have any effect at all...

did you mail your hoster and ask them what you can do about this?
