Zend Studio 13 中未定义的内置函数

Question

我在 Zend Studio 13 中创建了 PHP7 项目，但收到这样的警告 Call to undefined function 'dba_open'。为什么 Zend Studio 不识别这些函数？

dba_open
dba_close
dba_fetch
mhash

有什么解决办法吗？

Answer 1

Zend 并未为 Zend Studio 中的所有扩展提供语言支持。

为不受支持的扩展提供的语言实体添加支持的最有效方法无疑是创建存根。 所有受支持的 PHP 实体的描述 "stub" 文件可在此目录中找到： /.metadata/.plugins/org.eclipse.php.core/语言 这也是您应该放置存根文件的位置。

Answer 2

从下面复制 PHP 代码。创建文件 DBA.php 并将其放入文件夹 workspace/.metadata/.plugins/org.eclipse.php.core/__language__/languagecode/DBA.php

语言代码 - 8 位十六进制数字名称

您将无法调试具有这些功能的代码，但至少不再有警告。

/**
dba_open() establishes a database instance for path with mode using handler.

@param path string <p>Commonly a regular path in your filesystem.</p>

@param mode string <p>It is r for read access, w for read/write access to an already existing database,
c for read/write access and database creation if it doesn't currently exist, and n for create,
truncate and read/write access. The database is created in BTree mode, other modes (like Hash or Queue)
are not supported.<br>
<strong>Note:</strong><br>
There can only be one writer for one database file. When you use dba on a web server and more than
one request requires write operations they can only be done one after another. Also read during write
is not allowed. The dba extension uses locks to prevent this.
</p>

@param handler string <p>The name of the handler which shall be used for accessing path. It is passed all
optional parameters given to dba_open() and can act on behalf of them.</p>
