PHP 7.1.21 Released

apd_set_session_trace

(PECL apd 0.2-0.4)

apd_set_session_traceStarts the session debugging

说明

void apd_set_session_trace ( int $debug_level [, string $dump_directory = ini_get("apd.dumpdir") ] )

Starts debugging to apd_dump_{process_id} in the dump directory.

参数

debug_level

由加上 XXX_TRACE 常量而形成的整数。

不建议使用 MEMORY_TRACE。这会很慢且似乎不精确。 ASSIGNMENT_TRACE 还未被实现。

要打开所有跟踪功能(TIMING, FUNCTIONS, ARGS SUMMARY (比如 strace -c)) 则使用 99 作为值。

dump_directory

The directory in which the profile dump file is written. If not set, the apd.dumpdir setting from the php.ini file is used.

返回值

没有返回值。

范例

Example #1 apd_set_session_trace() example

<?php
apd_set_session_trace
(99);
?>
