<h2>EDITED 01</h2> If what you need is the number of lines inside the file: <pre><code><?php $path = tempnam(sys_get_temp_dir(), '').'.txt'; $fileInfo = new SplFileInfo($path); $fileObject = $fileInfo->openFile('a+'); $fileObject->fwrite("Foo".PHP_EOL); $fileObject->fwrite("Bar".PHP_EOL); echo count(file($path)); // outputs 2 ?> </code></pre> <hr> <h2>EDITED 02</h2> This is your code above, but without entering into infinite loops due to the file pointer: <pre><code><?php $path = tempnam(sys_get_temp_dir(), '').'.txt'; $fileInfo = new SplFileInfo($path); $fileObject = $fileInfo->openFile('a+'); $fileObject->fwrite("Foo".PHP_EOL); $fileObject->fwrite("Bar"); foreach($fileObject as $line_num => $line) { echo 'Line: '.$line_num.' "'.$line.'"'." "; } echo 'Total Lines:' . $fileObject->key(); ?> </code></pre> Outputs <blockquote> Line: 0 "Foo " Line: 1 "Bar" Total Lines:2 </blockquote> <hr> <h2>ORIGINAL ANSWER</h2> The logic applied was a bit off. I simplified the code: <pre><code><?php // set path to tmp with random file name echo $path = tempnam(sys_get_temp_dir(), '').'.txt'; echo " "; // new object $fileInfo = new \SplFileInfo($path); // open to write $fileObject = $fileInfo->openFile('a'); // write two lines $fileObject->fwrite("Foo".PHP_EOL); $fileObject->fwrite("Bar".PHP_EOL); // open to read $fileObject2 = $fileInfo->openFile('r'); // output contents echo "File Exists: " .file_exists($path); echo " "; echo "File Contents: " . file_get_contents($path); echo " "; // foreach line get line number and line contents foreach($fileObject2 as $line_num => $line) { echo 'Line: '.$line_num; echo ' With: "'.$line.'" is the end? '.($fileObject2->eof()?'yes':'no')." "; } ?> </code></pre> Outputs: <blockquote> /tmp/EAdklY.txt File Exists: 1 File Contents: Foo Bar Line: 0 With: "Foo " is the end? no Line: 1 With: "Bar " is the end? no Line: 2 With: "" is the end? yes </blockquote>

Guidance

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.
