Need a loop for this code

I have this code:
Code: Select all
$findTd = '<td colspan="2">';
$start_td_pos = strpos($extract, $findTd); //73
$find_end_td = '</td></tr>';
$end_td_pos = strpos($extract, $find_end_td); //105
$length_grab1 = $end_td_pos - $start_td_pos;
$extract_hour_channel = substr($extract, $start_td_pos, $length_grab1);
echo $extract_hour_channel.'<br />'; //hour and name of the channel
But I want a loop to display all the strings that are inside $findTd and $find_end_td.
Any help would be appreciated

What do the strings that are inside $extract, $findTd and $find_end_td look like? Examples please.

$extract holds a large html file.
But I solved the thing, here is my code:
Code: Select all
while($i==0) {
$findTd = '<td colspan="2">';
$start_td_pos = strpos($extract, $findTd); //73
$find_end_td = '</td></tr>';
$end_td_pos = strpos($extract, $find_end_td); //105
$length_grab1 = $end_td_pos - $start_td_pos;
$value = substr($extract, $start_td_pos, $length_grab1);
echo $value.'<br />'; //hour and name of the channel
$start_new_extract = $end_td_pos + strlen($find_end_td);
$extract = substr($extract, $start_new_extract);
if(strstr($extract,$findTd)==FALSE) {
$i=1;
}
}
This finds all strings that are inside <td colspan="2"> </td>

Not an answer to your original question, but...
Code: Select all
preg_match_all('#<td colspan="2">(.+?)</td>#s', $extract, $matches);
print_r($matches[1]);

How can I print just the values?

With this code:
1. preg_match_all('#<td colspan="2">(.+?)</td>#s', $extract, $matches);
2. print_r($matches[1]);
you will get not just the things inside the td's but also the td's.
How can I just get the strings inside the td's?

$matches[0] contains the tds with values, $matches[1] contains just the values inside the tds.
