106 <p>To display the array representing the data saved in
<code>data/datastore.php
</code>, use the following snippet:
</p>
107 <div class=
"sourceCode"><pre class=
"sourceCode php"><code class=
"sourceCode php"><span class=
"kw">$data
</span> =
<span class=

108 <span class=

</span> =
<span class=
"fu">unserialize
</span><span class=
"ot">(
</span><span class=
"fu">gzinflate
</span><span class=
"ot">(
</span><span class=
"fu">base64_decode
</span><span class=

</span><span class=

</span><span class=

</span>
111 <span class=

>"</span><span class=
"ot">;
</span>
112 <span class=
"fu">exit
</span><span class=
"ot">;
</span></code></pre></div>
113 <p>This will output the internal representation of the datastore,
"unobfuscated
" (if this can really be considered obfuscation).
</p>
114 <p>Alternatively, you can transform to JSON format (and pretty-print if you have
<code>jq
</code> installed):
</p>
115 <pre><code>php -r
'print(json_encode(unserialize(gzinflate(base64_decode(preg_replace(
"!.*/\* (.+) \*/.*!
",
"$
1", file_get_contents(
"data/datastore.php
")))))));
' | jq .
</code></pre>
116 <h3 id=
"changing-the-timestamp-for-a-link">Changing the timestamp for a link
</h3>
118 <li>Look for
<code><input type=
"hidden
" name=
"lf_linkdate
" value=
"{$link.linkdate}
"></code> in
<code>tpl/editlink.tpl
</code> (line
14)
</li>
119 <li>Replace
<code>type=
"hidden
"</code> with
<code>type=
"text
"</code> from this line
</li>
120 <li>A new date/time field becomes available in the edit/new link dialog.
</li>
121 <li>You can set the timestamp manually by entering it in the format
<code>YYYMMDD_HHMMS
</code>.
