PHP regex find and replace in text and numbers

I have input in that format:

Text number1: 12.3456°, text number2: 78.9012°.

I want replace this to here with PHP:

GPS:12.3456,78.9012: Text number1: 12.3456°, text number2: 78.9012°.

So, again, the input in big text:

"

Bla bla bla, random text, bla bla... Text number1: 12.3456°, text number2: 78.9012°. And more text...

"

This output needed:

"

Bla bla bla, random text, bla bla... GPS:12.3456,78.9012: Text number1: 12.3456°, text number2: 78.9012°. And more text...

"

Output need to append this BEFORE what I searching: "GPS:12.3456,78.9012:"

The 2 numbers also in all line different: 12.3456 and 78.9012 All others are fixed. (Spaces, other characters.)

If you just now how to detect and get this line from big text: "Text number1: 12.3456°, text number2: 78.9012°." Also helps. If I have this line, I can find numbers and replace. I will use explode to detect numbers (finding space before and ° after the number) and str_replace to replace the input to output. I know not this is the best way but I know that functions.

(Sorry, text formatting not working as I want. I fixed the input, output, changed "," to space)

Thanks!

$text = 'Bla bla bla, random text, bla bla... Text,number1: 12.3456°, text,number2: 78.9012°. And more text...  ';

echo preg_replace('%([\w\s,]+:\s(\d+\.\d+)°,\s[\w\s,]+:\s(\d+\.\d+)°)%ui', ' GPS:$2,$3: $1', $text);



//Output: Bla bla bla, random text, bla bla... GPS:12.3456,78.9012: Text,number1: 12.3456°, text,number2: 78.9012°. And more text...

$text = 'Bla bla bla, random text, bla bla...
Text number1: 12.3456°, text number2: 78.9012°.
And more text';
$pattern = '#[a-zá-úàü\d ,]+:\s?([\d.]+)°[^:]+:\s?([\d.]+)°#i';
return preg_replace_callback($pattern, function($match) {
    return sprintf("GPS:%s,%s:\n%s.",
        $match[1],
        $match[2],
        $match[0]
    );
}, $text);

It's not pretty but I'm late for dinner!

<?
$text = 'Bla bla bla, random text, bla bla...
Text,number1: 12.3456°, text,number2: 78.9012°.
And more text...';

$lines = array();
foreach(explode("\r\n",$text) as $line){
    $match = array();
    preg_match_all('/\d{0,3}\.?\d{0,20}°/', $line, $result, PREG_PATTERN_ORDER);
    for ($i = 0; $i < count($result[0]); $i++) {
        $match[] = $result[0][$i];
    }
    if(count($match)>0){
        $lines[] = 'GPS:'.str_replace('°','',implode(',',$match));
    }
    $lines[] = $line;

}
echo implode('<br>',$lines);
?>

Bla bla bla, random text, bla bla...
GPS:12.3456,78.9012
Text,number1: 12.3456°, text,number2: 78.9012°.
And more text...
