An alias can be used internally to a phar archive to ensure that use of the <i>phar</i> stream wrapper to access internal files always works regardless of the location of the phar archive on the filesystem. Another alternative is to rely upon Phar's interception of <b>include()</b> or to use <a href="phar.interceptfilefuncs.html" class="function">Phar::interceptFileFuncs()</a> and use relative paths. </p> </div> <div class="refsect1 parameters"> <h3 class="title">Parameters</h3> <p class="para"> <dl> <dt> <span class="term"><i><tt class="parameter">alias</tt></i></span> <dd> <p class="para"> A shorthand string that this archive can be referred to in <i>phar</i> stream wrapper access. </p> </dd> </dt> </dl> </p> </div> <div class="refsect1 returnvalues"> <h3 class="title">Return Values</h3> <p class="para"> </p> </div> <div class="refsect1 errors"> <h3 class="title">Errors/Exceptions</h3> <p class="para"> Throws <b class="classname">UnexpectedValueException</b> when write access is disabled, and <a href="class.PharException.html" class="classname">PharException</a> if the alias is already in use or any problems were encountered flushing changes to disk. </p> </div> <div class="refsect1 examples"> <h3 class="title">Examples</h3> <p class="para"> <div class="example"> <p><b>Example #1 A <b>Phar::setAlias()</b> example</b></p> <div class="example-contents"><div class="phpcode"><code><span style="color: #000000"><span style="color: #0000BB"><?php<br /></span><span style="color: #007700">try {<br /> </span><span style="color: #0000BB">$phar </span><span style="color: #007700">= new </span><span style="color: #0000BB">Phar</span><span style="color: #007700">(</span><span style="color: #DD0000">'myphar.phar'</span><span style="color: #007700">);<br /> </span><span style="color: #0000BB">$phar</span><span style="color: #007700">-></span><span style="color: #0000BB">setAlias</span><span style="color: #007700">(</span><span style="color: #DD0000">'myp.phar'</span><span style="color: #007700">);<br />} catch (</span><span style="color: #0000BB">Exception $e</span><span style="color: #007700">) {<br /> </span><span style="color: #FF8000">// handle error<br /></span><span style="color: #007700">}<br /></span><span style="color: #0000BB">?></span></span></code></div> </div> </div> </p> </div> <div class="refsect1 seealso"> <h3 class="title">See Also</h3> <p class="para"> <ul class="simplelist"> <li class="member"><a href="phar.construct.html" class="function" rel="rdfs-seeAlso">Phar::__construct()</a></li> <li class="member"><a href="phar.interceptfilefuncs.html" class="function" rel="rdfs-seeAlso">Phar::interceptFileFuncs()</a></li> </ul> </p> </div></div><hr /><div style="text-align: center;"> <div class="prev" style="text-align: left; float: left;"><a href="phar.running.html">Phar::running</a></div> <div class="next" style="text-align: right; float: right;"><a href="phar.setdefaultstub.html">Phar::setDefaultStub</a></div> <div class="up"><a href="class.Phar.html">Phar</a></div> <div class="home"><a href="index.html">PHP Manual</a></div></div></body></html>⌨️ 快捷键说明
