[英]ini_set(“memory_limit”) in PHP 5.3.3 is not working at all
I had this working before : 我以前有这个工作:
echo ini_get("memory_limit")."\n";
ini_set("memory_limit","256M");
echo ini_get("memory_limit")."\n";
That would input this : 那将输入:
32M
256M
on a php script executed by command line. 在命令行执行的php脚本上。 I updated from 5.2 to 5.3, and from now, this directive is not working at all : this gives me :
我从5.2更新到5.3,从现在开始,此指令完全不起作用:这给了我:
32M
32M
and then make my script fail with a fatal Error... 然后让我的脚本因致命错误而失败...
I checked the php documentation, and googled it, and I didn't find anywhere that "memory_limit" had been deprecated. 我检查了php文档,并对其进行了谷歌搜索,没有发现“ memory_limit”已被弃用的任何地方。
Does anyone have a solution? 有没有人有办法解决吗?
If you have the suhosin extension enabled, it can prevent scripts from setting the memory limit beyond what it started with or some defined cap. 如果启用了suhosin扩展名,它可以防止脚本将内存限制设置为超出其开头或某些定义的上限。
http://www.hardened-php.net/suhosin/configuration.html#suhosin.memory_limit http://www.hardened-php.net/suhosin/configuration.html#suhosin.memory_limit
Most likely your sushosin updated, which changed the default of suhosin.memory_limit from disabled to 0 (which won't allow any updates to memory_limit). 最有可能是您的sushosin已更新,从而将suhosin.memory_limit的默认值从Disabled更改为0(不允许对memory_limit进行任何更新)。
On Debian, change /etc/php5/conf.d/suhosin.ini 在Debian上,更改/etc/php5/conf.d/suhosin.ini
;suhosin.memory_limit = 0
; suhosin.memory_limit = 0
to 至
suhosin.memory_limit = 2G
suhosin.memory_limit = 2G
Or whichever value you are comfortable with. 或您满意的任何价值。 You can find the changelog of Sushosin at http://www.hardened-php.net/hphp/changelog.html , which says:
您可以在http://www.hardened-php.net/hphp/changelog.html上找到Sushosin的变更日志,其中显示:
Changed the way the memory_limit protection is implemented
更改了memory_limit保护的实现方式
Here's a list of things that are worth checking: 以下是值得检查的事项列表:
Is Suhosin installed? 是否安装了Suhosin?
ini_set ini_set
ini_set('memory_limit', '512'); // DIDN'T WORK ini_set('memory_limit', '512MB'); // DIDN'T WORK ini_set('memory_limit', '512M'); // OK - 512MB ini_set('memory_limit', 512000000); // OK - 512MB
ini_set('memory_limit', '512'); // DIDN'T WORK ini_set('memory_limit', '512MB'); // DIDN'T WORK ini_set('memory_limit', '512M'); // OK - 512MB ini_set('memory_limit', 512000000); // OK - 512MB
ini_set('memory_limit', '512'); // DIDN'T WORK ini_set('memory_limit', '512MB'); // DIDN'T WORK ini_set('memory_limit', '512M'); // OK - 512MB ini_set('memory_limit', 512000000); // OK - 512MB
When an integer is used, the value is measured in bytes.
使用整数时,该值以字节为单位。 Shorthand notation, as described in this FAQ , may also be used.
也可以使用本常见问题解答中所述的速记符号。

Sets the value of the specified directive.
设置指定指令的值。 This can not be used in .htaccess files.
这不能在.htaccess文件中使用。 Any directive type set with php_admin_value can not be overridden by .htaccess or ini_set().
.htaccess或ini_set()不能覆盖任何用php_admin_value设置的指令类型。 To clear a previously set value use none as the value.
要清除先前设置的值,请不使用任何值。

Works for me, has nothing to do with PHP 5.3. 对我有效,与PHP 5.3无关。 Just like many such options it cannot be overriden via
ini_set()
when safe_mode is enabled. 与许多此类选项一样,启用safe_mode时不能通过
ini_set()
覆盖它。 Check your updated php.ini
(and better yet: change the memory_limit there too). 检查您更新的
php.ini
(更好的是:也在那里更改memory_limit)。
Ubuntu 10.04 comes with the Suhosin patch only, which does not give you configuration options. Ubuntu 10.04仅随附Suhosin补丁,该补丁不提供配置选项。 But you can install php5-suhosin to solve this:
但是您可以安装php5-suhosin来解决此问题:
apt-get update
apt-get install php5-suhosin
Now you can edit /etc/php5/conf.d/suhosin.ini and set: 现在,您可以编辑/etc/php5/conf.d/suhosin.ini并设置:
suhosin.memory_limit = 1G
Then using ini_set will work in a script: 然后使用ini_set将在脚本中工作:
ini_set('memory_limit', '256M');
Let's do a test with 2 examples: 让我们用两个示例进行测试:
<?php
$memory = (int)ini_get("memory_limit"); // Display your current value in php.ini (for example: 64M)
echo "original memory: ".$memory."<br>";
ini_set('memory_limit','128M'); // Try to override the memory limit for this script
echo "new memory:".$memory;
}
// Will display:
// original memory: 64
// new memory: 64
?>
The above example doesn't work for overriding the memory_limit value. 上面的示例不适用于覆盖memory_limit值。 But This will work:
但这将起作用:
<?php
$memory = (int)ini_get("memory_limit"); // get the current value
ini_set('memory_limit','128'); // override the value
echo "original memory: ".$memory."<br>"; // echo the original value
$new_memory = (int)ini_get("memory_limit"); // get the new value
echo "new memory: ".$new_memory; // echo the new value
// Will display:
// original memory: 64
// new memory: 128
?>
You have to place the ini_set('memory_limit','128M');
您必须放置
ini_set('memory_limit','128M');
at the top of the file or at least before any echo . 在文件的开头或至少在回声之前 。
As for me, suhosin wasn't the solution because it doesn't even appear in my phpinfo(), but this worked: 对于我来说, suhosin并不是解决方案,因为它甚至都没有出现在我的phpinfo()中,但是这样做有效:
<?php
ini_set('memory_limit','2048M'); // set at the top of the file
(...)
?>
