I was running this code
<img src="../graphics/g_builder.php?type=funil&interval=1"/>
<img src="../graphics/g_builder.php?type=funil&interval=3"/>
<img src="../graphics/g_builder.php?type=conversao&interval=2"/>
<img src="../graphics/g_builder.php?type=conversao&interval=3"/>
<img src="../graphics/g_builder.php?type=nps&interval=2"/>
That generates an image in a folder that the rest of the code use later, but it only works one time or pressing ctrl +f5 which clears cache if im not wrong...
So i need a way to renew this images everytime i call the php or somehow clear the cache but without using headers... what can i do?
