我有一个php脚本，由于某种原因，它在mysqli执行后跳过了一些打印语句，但在循环后打印。有任何想法吗？我将脚本移至其他服务器。 DB（仍然）在阿肯色州的小石城中。脚本服务器位于阿肯色州的小石城，现在位于宾夕法尼亚州。可以。我看到了：
PING littlerock db (ip...) 56(84) bytes of data.
64 bytes from littlerock (ip...): icmp_seq=1 ttl=56 time=36.5 ms
它继续运行，几分钟后我按ctrl-c退出。
当我在旧服务器上运行脚本时，需要5分钟。在新服务器上，它需要一个小时，并且会在一段时间内丢失最后几个打印语句。 （请参见//缺少）
我听说绑定错误，然后脚本在绑定之后停止，但是在这种情况下，它在while循环之后继续。但是我没有更改查询或绑定，所以应该没问题。我不确定该如何调试或在线搜索什么。我尝试注释掉并逐渐取消注释，发现在stmt4在while循环中执行之后，脚本变得很慢。
我做了
php -i | grep max_execution_time
然后查看
max_execution_time => 0 => 0
我认为这意味着没有最大值，因此不应超时。
我做了一个strace php script.php，看到了这种东西：
write(9, "\17\0\0\0\27\1\0\0\0\0\1\0\0\0\0\0\2AR", 19) = 19
read(9, "\1\0\0\1\0017\0\0\2\3def\7netcool\7domains\7do"..., 16384) = 93
poll([{fd=6, events=POLLIN|POLLPRI}], 1, 0) = 0 (Timeout)
poll([{fd=6, events=POLLIN|POLLPRI}], 1, 0) = 0 (Timeout)
write(6, "\210\0\0\0\27\1\0\0\0\0\1\0\0\0\4\20\0\0\f10.66.46.141\17"..., 140) = 140
read(6, "\7\0\0\1\0\0\0\2\0\4\0", 16384) = 11
poll([{fd=8, events=POLLIN|POLLPRI}], 1, 0) = 0 (Timeout)
poll([{fd=8, events=POLLIN|POLLPRI}], 1, 0) = 0 (Timeout)
write(8, "\32\0\0\0\27\1\0\0\0\0\1\0\0\0\0\0\6Adtran\6TA5000", 30) = 30
read(8, "\1\0\0\1\3M\0\0\2\3def\7netcool\22vendor_mod"..., 16384) = 286
poll([{fd=9, events=POLLIN|POLLPRI}], 1, 0) = 0 (Timeout)
poll([{fd=9, events=POLLIN|POLLPRI}], 1, 0) = 0 (Timeout)
write(9, "\17\0\0\0\27\1\0\0\0\0\1\0\0\0\0\0\2AR", 19) = 19
，但随后却是ctrl-c / z。

答案 0 :(得分：1)
请参见下循环：
while($row = oci_fetch_array($ora_stmt, OCI_ASSOC+OCI_RETURN_NULLS))
当循环开始时，$ i为0，因此您可以看到文本“ 5 b” ...
然后由于表达式$ i ++，$ i将为1。因此，关于if语句的任何其他条件都不正确。
