<h1>sparqllib.php</h1>
<p>Simple library to query SPARQL from PHP.</p>

<h2><a name='intro'></a>Intro</h2>
<p>This is a very simple RDF library to query SPARQL from PHP. It currently ignores language and datatype information to make it feel as similar as possible to the normal PHP SQL libraries.</p>
<ul>
<li>Download: <a href='/download.php/sparqllib.php'>sparqllib.php</a> (LGPL)</li>
</ul>
<p>If you want to get started really quickly, the following command line will install sparqllib.php. You should run it in the same directory as where your PHP code resides.</p>
<div class='example_code'>
curl -s http://graphite.ecs.soton.ac.uk/download.php/sparqllib.php -o sparqllib.php
</div>
<p>Or get the <a href='https://github.com/cgutteridge/PHP-SPARQL-Lib'>latest version from Github</a>.</p>
<p>Also hosted on this site is <a href='/'>Graphite</a>, a simple PHP library for querying RDF data.</p>

<?php
#<h2 style='clear:both'><a name='quick'></a>Really Quick Interface</h2>
#<p>If you just want to get the damn data, use this style.</p>
#render_example( "examples/quick.php" );
?>
<h2 style='clear:both'><a name='classic'></a>Classic mysql_query style</h2>
<p>The library provides functions very similar to mysql_* for comfort.</p>
<?php
render_example( "examples/basic.php" );
?>

<h2 style='clear:both'><a name='object'></a>Object style</h2>
<p>The object-based interface is a bit tidier than the sparql_ style methods.</p>
<?php
render_example( "examples/object.php" );
?>

<h2 style='clear:both'><a name='quick'></a>Quick and dirty</h2>
<p>The quickest way to get at some data.</p>
<?php
render_example( "examples/quick.php" );
?>

<h2 style='clear:both'><a name='rows'></a>Rows, Values and Datatypes</h2>
<p>All the interfaces end up giving you an array of values, one per field. They also define the type of each value and, if available, the datatype or language of a literal value.</p>
<table class='info_table'>
<tr><th style='padding-right:1em'>$row["myfield"]</th><td>The value of the field in this row of results.</td></tr>
<tr><th style='padding-right:1em'>$row["myfield.type"]</th><td>The type of the value. Either 'uri','bnode' or 'literal'.</td></tr>
<tr><th style='padding-right:1em'>$row["myfield.datatype"]</th><td>This <i>may</i> be set for literal values.</td></tr>
<tr><th style='padding-right:1em'>$row["myfield.language"]</th><td>This <i>may</i> be set for literal values.</td></tr>
</table>
<?php
render_example( "examples/types.php" );
?>
<h2 style='clear:both'><a name='caps'></a> Endpoint Capabilities Tests</h2>

<p>This allows you to test if an endpoint supports and allows certain SPARQL features. It doesn't currently cache, so every test results in a query. I have been trying to write software which runs against multiple endpoints and it's really frustrating not knowing what an endpoint can/can't do.</p>
<p>I'm very open to suggestions for useful additional tests (with example SPARQL which runs in some endpoints, but not others)</p>

<?php
render_example( "examples/capabilities.php" );
