For instance: class Foo {} // some code here class Foo {} That second Foo cannot redeclare class laravel migration would throw the error. share|improve this answer answered Apr 2 '09 at 3:15 whichdan 1,6061210 55 This answer is not as helpful as AaronLS's. I don't think the questioner would have asked the question if (s)he had written an obvious repetition like this (even in quite a complex situation). The include_once tip helps to clarify an obscure feature of PHP. –DavidHyogo Mar 20 '13 at 2:12 2 This error might also occur if you define the __construct method more than once. –Jack Trowbridge Sep 1 '13 at 21:27 1 AaronLS's answer is perfect.. –Krunal Panchal Feb 19 '14 at 4:13 3 Just use include_once('FooBar.php') to include your class. The name of the function is self-explanatory. –Marco Matarazzi Feb 19 '14 at 13:49 1 AaronLS's answer is much higher rated, and you can find it way down here. –qris Oct 7 '14 at 11:48 | show 2 more comments up vote 266 down vote You have a class of the same name declared more than once. Maybe via multiple includes. When including other files you need to use something like include_once "something.php"; to prevent multiple inclusions. It's very easy for this to happen, though not always obvious, since you could have a long chain of files being included by one another. share|improve this answer answered Apr 2 '09 at 3:15 AaronLS 20k1190139 8 this was really help full! –Marci-man Aug 6 '11 at 17:49 4 avoid include_once, it's slow,

It's not valid to include a class twice in any version of PHP. This has to do with somehow having two separate copies of Views being invoked in a way that shouldn't be possible. It's not really up to Views to defend against this stuff; it's a bug in whatever is including the second copy of Views.

As merlinofchaos stated, it is not Views' responsibility to make sure that a particular php file is included only once. If you're getting this error make sure
Categories: Developing Tags: Code APC stands for the Alternative PHP Cache. PHP is a dynamic language that is compiled on-demand into bytecode at execution time. To improve performance, APC stores this bytecode so that it can be reused instead of having to be recompiled each time. Pantheon provides APC by default across all plans, but the size of the APC memory cache (apc.shm_size) varies depending on the service level. Frequently Asked Questions Can APC be used as a cache backend on Pantheon? Yes, APC can be used as a cache backend or a "key-value store"; however, this is not recommended. APC lacks the ability to span multiple server environments. Instead, Pantheon provides Redis as a caching backend, which has better performance. What happens if the APC memory cache is too small? If the size of the scripts loaded exceed the size of the APC cache, the cache will be flushed and rebuilt, resulting in slow execution time. Symptoms of this will include the following message in dev environments and in watchdog logs: Warning: require_once(): Unable to allocate memory for pool. In these circumstances, either increasing the SHM size by upgrading your account, or reducing the amount of scripts read by PHP by disabling unneeded modules typically resolves the issue. To learn more about how much memory your site is using, visit the site's New Relic dashboard. How can I determine what my current APC settings are? Search for shm_size in phpinfo. See Securely Working with phpinfo. Can the shm_size be configured manually? No, as this is not a runtime configuration, the shm_size cannot be changed. If a greater shm_size is needed, then the two options available are to optimize the codebase to operate within the service level, or to upgrade the site account for a larger shm_size allocation. Troubleshooting I got a fatal error about redeclaring a class in Drupal core; what should I do? In some rare cases, there is a known issue with APC where it attempts to load a file that has already been cached. For example: Fatal error: Cannot redeclare class InsertQuery_mysql in ... on line 87 If this happens often, a workaround would be to place the following at the top of the file in question: if (!class_exists('NAMEOFCLASSBEINGREDECLARED')) { then closing the condition with the corresponding bracket at the bottom: } How do I clear the APC opcode cache? Sometimes, due to (very rare) corruption, the APC opcode cache will need to be cleared. Manual To do this manually, write a small script
