```
$firstElement = ($t = functionThatReturnsAnArray()) ? $t[0] : false;
```
and for strings you could use
```
$string = (($t = functionThatReturnsAnArray())==0) . $t[0];

.. Interesting problem
Draco | Sometimes I'll change the function, so it can optionally return an element instead of the entire array:

return ($n === NULL ? $myArray : $myArray[$n]);

This is because bread with lots of rye rises due to polysaccharates called "pentosans" (if i remember correctly) being sticky and holding in the carbon dioxide bubbles. With heat, an enzyme in rye called "amylase" will start ea... | I've found that a lower pH (more acidity) weakens the gluten and makes the crumb less chewey or less rubbery.
Certainly one thing to try before taking the step of adding vinegar to a bread recipe is to replace any bread flour with general purpose flour instead -- it should have the same effect. |

You asked how to upload SVG in WordPress 4.9.8 (the current version at the time of writing). You mention that you "tried uploading after installing different plugins". You don't say which plugins, no... | ```
//add SVG to allowed file uploads
function add_file_types_to_uploads($file_types){
$new_filetypes = array();
$new_filetypes['svg'] = 'image/svg+xml';
$file_types = array_merge($file_types, $new_filetypes );
return $file_types;
}
add_action('upload_mimes', 'add_file_types_to_uploads');
