[SOLVED] searching for consecutive six 0-9 numbers in a string

[hammadtariq]

Hello Guys,

          I have a task in hand in which I am getting strings which are in fact subjects of emails and they are like

 

"This should be done! 568975/12/tinup"

"456789 is your reference"

"I am in 456789 area"

 

All I need is to take out consecutive six matching numbers and that will be my reference number. Reference number is always in six digits and I need to take out any occurance of six digit numbers and stripping out everything else. I considered using strspn() but thats not working I guess that is not for search like this and I am really bad in using preg_match, can any one help me please?

$s = 'This should be done! 568975/12/tinup';
preg_match('/([0-9]){6}/', $s, $m);
echo $m[0];
