Is there a way to redirect the output behaviour of a php function like "echo" and make it so that it's new output when called anytime points to the file descriptor I provide?

There is. You can use output buffering.
<?php function callback($buffer) { return $buffer; } ob_start("callback"); ?>
Then when you
echo
anything, yourcallback()
function will be called, and you can do whatever you want with the output.本回答被题主选为最佳回答 , 对您是否有帮助呢?解决 无用评论 打赏 举报
