Regular php expression between tags

In case the only way to get that number is by the styles of the td try this:

$texto = 'xxxxxx <td style="background-color:#b0c400;border-bottom:1px solid #ffffff;text-align:right;padding:0px 5px 0px 5px;color:#000000;">2769</td> xxxxxx';

$expr_reg = '%<td style="background-color:#b0c400;border-bottom:1px solid #ffffff;text-align:right;padding:0px 5px 0px 5px;color:#000000;">(\d*?)</td>%si';
if (preg_match($expr_reg, $texto, $coincidencias)) {
    # Successful match
    print_r($coincidencias);
} else {
    # Match attempt failed
    echo "Mala suerte";
}

In $ matches [1] you have your number

You should not use regular expressions to process HTML. Just a small change in the HTML would make your regex fail. A space of more, a change in the attributes of the tag, a comment, or more complex structures, would make even a gigantic regex not follow the rules.

It's very easy to process HTML with DOM , they are the tools that They are designed for that.

The DOM is simply generated as follows:

$html = '<td style="background-color:#b0c400;border-bottom:1px solid #ffffff;text-align:right;padding:0px 5px 0px 5px;color:#000000;">2769</td>';

//Generar el DOM
$dom = new DOMDocument;
$dom->loadHTML($html, LIBXML_COMPACT | LIBXML_HTML_NOIMPLIED | LIBXML_NONET);

And we can get all the text without tags:

//Eliminar todos los tags
$sin_tags = $dom->textContent;

echo "Contenido de texto de toda la página:\n" . $sin_tags;    // => 2769

Or, if the HTML has more tags and you're only interested in the first <td> :

//Obtener todos los TD
$td_nodelist = $dom->getElementsByTagName('td');
//Obtener el primer TD
$td = $td_nodelist->item(0);

//Obtener el contenido de texto del tag
$numero = $td->textContent;

echo "\n\nContenido del TD:\n" . $numero;    // => 2769

Result:

Contenido de texto de toda la página:
2769

Contenido del TD:
2769
