I have a HTML-Code. The structure is always the same. But i don't know, how i can extract all numbers from the brackets.
Example-Code:
<table align="left" border="0" cellpadding="0" cellspacing="1">
<tbody><tr>
<td style="padding-right:0.5em;padding-bottom:1px;white-space:nowrap;font-size:10px;" align="left">
5 Sterne:
</td>
<td style="min-width:60; background-color: #eeeecc" class="tiny" title="73%" align="left" width="60"><div style="background-color:#FFCC66; height:13px; width:73%;"></div></td>
<td style="font-family:Verdana,Arial,Helvetica,Sans-serif;;font-size:10px;" align="right"> (96)</td>
</tr>
<tr>
<td style="padding-right:0.5em;padding-bottom:1px;white-space:nowrap;font-size:10px;" align="left">
4 Sterne:
</td>
<td style="min-width:60; background-color: #eeeecc" class="tiny" title="11%" align="left" width="60"><div style="background-color:#FFCC66; height:13px; width:11%;"></div></td>
<td style="font-family:Verdana,Arial,Helvetica,Sans-serif;;font-size:10px;" align="right"> (15)</td>
</tr>
<tr>
<td style="padding-right:0.5em;padding-bottom:1px;white-space:nowrap;font-size:10px;" align="left">
3 Sterne:
</td>
<td style="min-width:60; background-color: #eeeecc" class="tiny" title="7%" align="left" width="60"><div style="background-color:#FFCC66; height:13px; width:7%;"></div></td>
<td style="font-family:Verdana,Arial,Helvetica,Sans-serif;;font-size:10px;" align="right"> (10)</td>
</tr>
<tr>
<td style="padding-right:0.5em;padding-bottom:1px;white-space:nowrap;font-size:10px;" align="left">
2 Sterne:
</td>
<td style="min-width:60; background-color: #eeeecc" class="tiny" title="3%" align="left" width="60"><div style="background-color:#FFCC66; height:13px; width:3%;"></div></td>
<td style="font-family:Verdana,Arial,Helvetica,Sans-serif;;font-size:10px;" align="right"> (4)</td>
</tr>
<tr>
<td style="padding-right:0.5em;padding-bottom:1px;white-space:nowrap;font-size:10px;" align="left">
1 Stern<span style="color:#FFFFFF">e</span>:
</td>
<td style="min-width:60; background-color: #eeeecc" class="tiny" title="4%" align="left" width="60"><div style="background-color:#FFCC66; height:13px; width:4%;"></div></td>
<td style="font-family:Verdana,Arial,Helvetica,Sans-serif;;font-size:10px;" align="right"> (6)</td>
</tr>
<tr><td> </td><td><div style="width:60px;"> </div></td><td> </td></tr>
</tbody></table>
In this case i need this numbers: 96, 15, 10, 4 and 6.
Please give me a tip, which function is good for it.

Answer 1

You can use a DOM parser such as DOMDocument class to parse the HTML document. Since the structure is always the same, you can simply traverse the DOM using an XPath expression and grab the text from the third <td> node. Once you have the node value, you can use a simple preg_replace() to get the number:
$doc = new DOMDocument;
$doc->loadHTML($html);
$xpath = new DOMXPath($doc);
foreach ($xpath->query('//table/tbody/tr/td[3]/text()') as $node) {
$number = preg_replace('~\D~', '', $node->nodeValue);
echo $number . '<br/>';
}
Demo.

Answer 2

preg_match_all('~\((\d+)\)~',$content,$numbers);
print_r($numbers); // example to print results
output:
Array
(
[0] => Array
(
[0] => (96)
[1] => (15)
[2] => (10)
[3] => (4)
[4] => (6)
)
[1] => Array
(
[0] => 96
[1] => 15
[2] => 10
[3] => 4
[4] => 6
)
)
