标签: register-tick-function

我想用来register_tick_function()挂钩以下调用并打印他们的堆栈跟踪debug_backtrace().

如果我运行以下代码.

<?php

function dump() {
  // Replace this with var_dump(debug_backtrace()); to print the entire trace.
  foreach (debug_backtrace() as $trace)
    echo("Function ${trace['function']}() has been called" . PHP_EOL);
}

declare(ticks = 1);
register_tick_function('dump');

print("");
array_search('green', Array());

它只打印dump()功能.

Function dump() has been called
Function dump() has been called
Function dump() has been called

为什么我没有看到print()和array_search()跟踪数据？就像堆栈在调用之前已经重置一样dump().我也很确定它在过去是否正常工作.
