I want to fetch only the numbers (957119941) from this string using preg_match.

This shouldn't be too hard.
这应该不会太难。
$str = '<div id="post_message_957119941">';
if ( preg_match ( '/post_message_([0-9]+)/', $str, $matches ) )
{
print_r($matches);
}
Output:
输出：
Array ( [0] => post_message_957119941 [1] => 957119941 )
Array ( [0] => post_message_957119941 [1] => 957119941 )
So the desired result will always be in: $matches[1]
所以想要的结果总是在： $matches[1]
Is that what you need?
那是你需要的吗？
