    <p>I've created a function to overlay text onto images, but I'm scratching my head to find a way of outputting the image in a way in which it can be utilised within another script or outputted to the screen.</p> <p>I can call this function from a php script, passing it the image and the text to use, but when the function returns the data - it takes over the page due to the header - all I get as output is the image.</p> <p>I suspect this is an easy one and just shows a hole in my PHP knowledge - can someone set me straight here?</p> <p>Thanks!</p> <p>function makeimage($file, $text) { ob_start(); $x = getimagesize($file); $width = $x[0]; $height = $x[1]; $type = $x[2];</p> <pre><code> //header('Content-type: $type'); if ($type == 1) { $im = imagecreatefromgif($file); } elseif ($type==2) { $im = imagecreatefromjpeg($file); } elseif ($type==3) { $im = imagecreatefrompng($file); } // Create some colors $white = imagecolorallocate($im, 255, 255, 255); $grey = imagecolorallocate($im, 128, 128, 128); $black = imagecolorallocate($im, 0, 0, 0); // Replace path by your own font path $font = 'arial.ttf'; // Add some shadow to the text imagettftext($im, 20, 0, 11, 21, $grey, $font, $text); // Add the text imagettftext($im, 20, 0, 10, 20, $black, $font, $text); ob_clean(); //to be sure there are no other strings in the output buffer imagepng($im); $string = ob_get_contents(); ob_end_clean(); return $string; </code></pre> <p>}</p> <p>I want to create this image, and then have it outputted in such a way as I can display it on screen in amongst all the other output.</p>

    1. COI don't understand what you mean by "inserted back into a string", which part do you want returned as a string and for what purpose?

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.
