    <p>I am creating a file using PHP but I am unable to create a new file in every execution of the application. I am generating an XML file using a database. I want a new file in every execution of my code, how can I do that?</p> <p>This is my code:</p> <pre><code>&lt;?php $config['mysql_host'] = "localhost"; $config['mysql_user'] = "root"; $config['mysql_pass'] = "root"; $config['db_name'] = "dcu"; $config['table_name'] = "readingsThreePhase"; //$config['table_name1'] = "miosD1"; mysql_connect($config['mysql_host'],$config['mysql_user'],$config['mysql_pass']); @mysql_select_db($config['db_name']) or die( "Unable to select database"); function writeMsg() { //echo "Hello world!"; $xml = "&lt;?xml version=\"1.0\" encoding=\"UTF-8\"?&gt;"; $root_element = $config['table_name']."D1"; $xml .= "&lt;$root_element&gt;"; $sql = "SELECT * FROM dcu.readingsThreePhase where meterId=3 order by recordTime DESC limit 1"; $result = mysql_query($sql); if (!$result) { die('Invalid query: ' . mysql_error()); } if(mysql_num_rows($result)&gt;0) { while($result_array = mysql_fetch_assoc($result)) { //$xml .= "&lt;".$config['table_name']."&gt;\n"; $xml .= "&lt;".$config['miosD1']."&gt;\n"; foreach($result_array as $key =&gt; $value) { if($value==NULL) { continue; } $xml .= "&lt;$key&gt;"; $xml .= "$value"; $xml .= "&lt;/$key&gt;\n"; } $xml.="&lt;/".$config['miosD1']."&gt;"; } } $xml .= "&lt;/$root_element&gt;"; header ("Content-Type:text/xml"); echo $xml; $file=fopen("xmlfilefirst.xml","a"); fwrite($file,$xml); fclose($file); } writeMsg(); $xml = "&lt;?xml version=\"1.0\" encoding=\"UTF-8\"?&gt;"; $root_element = $config['table_name']."s"; $xml .= "&lt;$root_element&gt;"; $sql = "SELECT * FROM dcu.readingsThreePhase where meterId=3 order by recordTime DESC limit 1"; $result = mysql_query($sql); if (!$result) { die('Invalid query: ' . mysql_error()); } if(mysql_num_rows($result)&gt;0) { while($result_array = mysql_fetch_assoc($result)) { $xml .= "&lt;".$config['table_name']."&gt;\n"; foreach($result_array as $key =&gt; $value) { if($value==NULL) { continue; } $xml .= "&lt;$key&gt;"; $xml .= "$value"; $xml .= "&lt;/$key&gt;\n"; } $xml.="&lt;/".$config['table_name']."&gt;"; } } $xml .= "&lt;/$root_element&gt;"; header ("Content-Type:text/xml"); echo $xml; $file=fopen("xmlfilefirst.xml","a"); fwrite($file,$xml); fclose($file); ?&gt; </code></pre>

    1. CO`fopen($new_filename, 'a')` instead of your hardcoded filename.

    2. COEverything in `writeMsg()` seems to have been duplicated after the function is called - you'll probably want to fix that.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
