When a relative path is specified (a path which does not begin with /, \, \\, or a Windows drive letter) the path provided will be applied against the current working directory. In many cases this is the directory in which the script resides unless it has been changed. Using the CLI sapi, this defaults to the directory from which the script was called. </p> <p class="simpara"> With some functions, such as <a href="function.fopen.html" class="function">fopen()</a> and <a href="function.file-get-contents.html" class="function">file_get_contents()</a>, <i>include_path</i> may be optionally searched for relative paths as well. </p> <p class="para"> <table border="5"> <caption><b>Wrapper Summary</b></caption> <colgroup> <thead valign="middle"> <tr valign="middle"> <th colspan="1">Attribute</th> <th colspan="1">Supported</th> </tr> </thead> <tbody valign="middle" class="tbody"> <tr valign="middle"> <td colspan="1" rowspan="1" align="left">Restricted by <a href="filesystem.configuration.html#ini.allow-url-fopen" class="link">allow_url_fopen</a></td> <td colspan="1" rowspan="1" align="left">No</td> </tr> <tr valign="middle"> <td colspan="1" rowspan="1" align="left">Allows Reading</td> <td colspan="1" rowspan="1" align="left">Yes</td> </tr> <tr valign="middle"> <td colspan="1" rowspan="1" align="left">Allows Writing</td> <td colspan="1" rowspan="1" align="left">Yes</td> </tr> <tr valign="middle"> <td colspan="1" rowspan="1" align="left">Allows Appending</td> <td colspan="1" rowspan="1" align="left">Yes</td> </tr> <tr valign="middle"> <td colspan="1" rowspan="1" align="left">Allows Simultaneous Reading and Writing</td> <td colspan="1" rowspan="1" align="left">Yes</td> </tr> <tr valign="middle"> <td colspan="1" rowspan="1" align="left">Supports <a href="function.stat.html" class="function">stat()</a></td> <td colspan="1" rowspan="1" align="left">Yes</td> </tr> <tr valign="middle"> <td colspan="1" rowspan="1" align="left">Supports <a href="function.unlink.html" class="function">unlink()</a></td> <td colspan="1" rowspan="1" align="left">Yes</td> </tr> <tr valign="middle"> <td colspan="1" rowspan="1" align="left">Supports <a href="function.rename.html" class="function">rename()</a></td> <td colspan="1" rowspan="1" align="left">Yes</td> </tr> <tr valign="middle"> <td colspan="1" rowspan="1" align="left">Supports <a href="function.mkdir.html" class="function">mkdir()</a></td> <td colspan="1" rowspan="1" align="left">Yes</td> </tr> <tr valign="middle"> <td colspan="1" rowspan="1" align="left">Supports <a href="function.rmdir.html" class="function">rmdir()</a></td> <td colspan="1" rowspan="1" align="left">Yes</td> </tr> </tbody> </colgroup> </table> </p> </div> </div><hr /><div style="text-align: center;"> <div class="prev" style="text-align: left; float: left;"><a href="resource.html">List of Resource Types</a></div> <div class="next" style="text-align: right; float: right;"><a href="wrappers.http.html">HTTP and HTTPS</a></div> <div class="up"><a href="appendices.html">Appendices</a></div> <div class="home"><a href="index.html">PHP Manual</a></div></div></body></html>⌨️ 快捷键说明
