在请求之间apc_store不起作用

如何解决在请求之间apc_store不起作用

$bar = \'BAR\';
apc_store(\'foo\',$bar);
var_dump(apc_fetch(\'foo\'));

一项要求之内。现在，如果我尝试在另一个请求上执行var_dump(apc_fetch(\'foo\'));，它将打印：

bool(false)

有什么帮助吗？我在gentoo上使用PHP 5.2，APC-3.1.9 这里PHPinfo（）关于APC的知识：

如果您需要其他信息，请告诉我这是我的安装方式：https://serverfault.com/questions/274261/Failed-installing-apc 我注意到一件事：在PHPinfo \'Configure命令中，我没有找到apc \'./ configure \'\'-disable-cli \' \'-disable-discard-path \' \'-disable-force-cgi-redirect \' \'-prefix = / usr / local / PHP5 \' \'-with-config-file-path = / usr / local / lib / PHP5 \'\'-with-pear = / usr / share / PHP5 \' \'-enable-exif \'\'-enable-ftp \' \'-enable-bcmath \'\'-enable-calendar \' \'-with-gd \'\'-enable-gd-native-ttf \' \'-with-freetype-dir \'\'-with-gettext \' \'-with-zlib-dir \'\'-with-imap \' \'-with-imap-ssl \' \'-with-png-dir = / usr \' \'-with-jpeg-dir = / usr \' \'-with-xpm-dir = / usr \'\'-with-openssl \' \'-with-kerberos \'\'-enable-sysvsem \' \'-启用sysvshm \'\'-with-mcrypt \' \'-with-iconv \'\'-enable-mbstring = all \' \'-启用mbregex \'\'-with-MysqL = / usr \' \'-with-MysqLi \'\'-with-curl \' \'-with-xsl \'

解决方法

可能您是在CGI上运行PHP（而不是您应该使用的FastCGI）-在另一个问题中看到我的答案，如果PHP在CGI上运行，为什么APC不起作用。 , 您的默认ttl（apc.ttl）为0秒，这很奇怪-请在存储值时尝试指定ttl（以秒为单位）：

apc_store(\'foo\',$bar,60);

, php.ini的内容

apc.enabled=\"1\"
apc.shm_segments=\"1\"
apc.shm_size=\"128M\"
apc.ttl=\"7200\"
apc.user_ttl=\"7200\"
apc.file_update_protection=\"3\"
apc.cache_by_default=\"0\"
apc.max_file_size=\"1M\"
apc.stat=\"0\"
apc.write_lock=\"1\"
apc.report_autofilter=\"0\"
apc.include_once_override=\"0\"
apc.localcache=\"1\"
apc.localcache.size=\"1024\"
apc.coredump_unmap=\"0\"
; Optional,Comment out them later on
apc.num_files_hint=\"5000\"
apc.user_entries_hint=\"5000\"
apc.gc_ttl=\"3600\"
apc.stat_ctime=\"0\"

apctest.php的内容

<?php
$bar = \'BAR\';
apc_store(\'foo\',$bar);
var_dump(apc_fetch(\'foo\'));
?>

apctest.php的结果

string \'BAR\' (length=3)

apctest2.php的内容

<?php
var_dump(apc_fetch(\'foo\'));
?>

apctest2.php的结果

string \'BAR\' (length=3)
