 |
|
hi
best way for limitation memory usage or manage output length for users is using ticks in smarty.(what your solution ?)
but have a problem with ticks in smarty.
if i using tick like this example :
| Code: |
$GLOBALS['SmartyStartTick'] = false;
register_tick_function(function(){
if($GLOBALS['SmartyStartTick'])
{
//my code for verify limitation
}
});
declare(ticks=1);
$GLOBALS['SmartyStartTick'] = true;
$smarty->display('eval:tpl');
$GLOBALS['SmartyStartTick'] = false;
//some code php
|
this example included proccess smarty and template but i want only include proccess template.(ticks only for template)
Is it enforceable?

I think you are missing one small point.
Smarty processing include 3 steps, not 2.
1. Template compilation.
2. Template substitution.
3. Template output.
The first step is cached by default, unless you request force recompilation.
The second step may be cached.
The third step is the output itself and of course can not be cached. |

I did not know. thanks.
i want all the ticks fire in user template.
for example :
| Code: |
{$a = 1} // tick 1 start
{$b = 2} // tick 2 start
{$b = 3} // tick 3 start
|
this code include 3 ticks. i want this 3 tick ! it's possible ? |

Sorry, but from your description it is not very clear for me, what you want to do.
May be someone else will be able to assist you. |

no problem please executed this php code :
| Code: |
$GLOBALS['tickStart'] = false;
register_tick_function(function($maxUsage){
if(!$GLOBALS['tickStart']) return;
$realMemoryUsageOfUser = memory_get_usage() - $GLOBALS['tickStart'];
echo 'Memory Usage : '.$realMemoryUsageOfUser.' Byte !<br>';
if($realMemoryUsageOfUser > $maxUsage)
exit('<span style="color:red">Warning : Allowed Memory is '.$maxUsage.' byte !</span>');
/*
for example :
in between timestamp 1 and 2 user allowed memory is 10 kb (in microsecond)
*/
},376);
declare(ticks=1){
$GLOBALS['tickStart'] = memory_get_usage();
$a = 1; echo '<span style="color:green">line 1 executed.</span><br>';
$b = 'abcdef'; echo '<span style="color:green">line 2 executed.</span><br>';
$c = rand(1,9); echo '<span style="color:green">line 3 executed.</span><br>';
for($i=0; $i<1000; $i++); echo '<span style="color:green">line 4 executed.</span><br>';
$GLOBALS['tickStart'] = false;
};
|
in above example in line 4 (real line is 19) execution is stop and this way can be effective in ddos attack !
example of smarty php compile file in compile directory (in my think):
| Code: |
register_tick_function('myfunc');
declare(ticks=1){
// php code in template after compile with smarty
}
unregister_tick_function('myfunc');
|
ok ? |
