This question already has an answer here: When is optimisation premature? 20 answers PHP has to parse the WHOLE file, creates some bytecode from it that represents the source code, and then executes that bytecode. It does not matter where you place your function - it will always be parsed and made into bytecode. Once it is bytecode, the execution path may differ, ie the function may not
这个问题在这里已经有了答案: 何时优化过早? 20个答案 PHP必须解析WHOLE文件,从它创建一些表示源代码的字节码,然后执行该字节码。 放置函数的位置并不重要 - 它将始终被解析并制作为字节码。 一旦它是字节码,执行路径可能会有所不同,即该函数可能不会被调用,但是我没有看到这会产生任何细微的差别。 总而言之,你在问微型优化。 如果您可以编写明确证明一种方法比另一种更好的代码,并且速度差异显着(即它们
The PHP array is one of PHP's core features. It is sparse, allows multi-typed keys in the same array, and supports set, dictionary, array, stack/queue and iterative functionality. But after working with PHP for a while now, I've found that quite a few of the array_* functions are much slower than you'd think at first glance. Like in the case of array_rand on a very large array (10
PHP array是PHP的核心功能之一。 它很稀疏,允许在同一个数组中使用多类型键,并且支持集合,字典,数组,堆栈/队列和迭代功能。 但是现在使用PHP一段时间后,我发现相当array_*函数比乍看起来要慢得多。 就像array_rand在一个非常大的数组(10000+)上一样。 array_rand实际上很慢,在使用php数组作为索引数组的情况下,类似rand( 0, array_length( $array ) - 1 )的函数比array_rand运行速度快得多。 现在到我的问题。
I started by googling, and found this article which talks about mutex tables. I have a table with ~14 million records. If I want to add more data in the same format, is there a way to ensure the record I want to insert does not already exist without using a pair of queries (ie, one query to check and one to insert is the result set is empty)? Does a unique constraint on a field guarantee the
我开始用google搜索,并找到了这篇谈论互斥表的文章。 我有一张约有1400万条记录的表格。 如果我想以相同的格式添加更多的数据,有没有办法确保我想插入的记录不存在,而不使用一对查询(即,一个查询来检查,一个要插入的结果集是空)? 一个字段上的unique约束是否保证insert将会失败,如果它已经在那里? 似乎只有一个约束,当我通过php发布插入时,脚本就会呱呱叫。 使用INSERT IGNORE INTO table 请参阅http://b

I have a breadcrumb in my website that's not working properly. When I go to a product like Equipment» Products» Railing» Heavy Railing» Waterproof» Superrail 2000 it shows me this breadcrumb properly as it should.

I've had a look over here but didn't find any details on the best file permissions. I also took a look at some of WordPress's form's questions over here too but anybody that suggests 777 obviously needs a little lesson in security. In short my question is this. What permissions should I have for the following: root folder storing all the WordPress content wp-admin wp-con
我已经看过这里,但没有找到关于最佳文件权限的任何细节。 我也在这里看了一些关于WordPress表单的问题,但是任何暗示777的人都明显需要一些安全方面的教训。 总之我的问题是这样的。 我应该具备以下哪些权限: 根文件夹存储所有的WordPress内容 可湿性粉剂管理员 WP-内容 WP-包括 然后在每个文件夹中的所有文件? 当您设置WP时,您(网络服务器)可能需要对文件进行写入访问。 所以访问权限可能需要宽松。 cho
