Search Problem

[Schlo_50]

Hey guys,

 

I have a problem and am in need of some assistance. I want to make a search facility to search for people by their telephone number. I have had a go but am running into problems with the results. Using the code below what happens is, if I search for '07' to find all mobile numbers I actually get every number with the combination '07' within it. E.g: '07' might find 07795986251 and 01207456658, but i only want the first.

 

Can somebody help?

 

                          $lines = file("data/vacancies.DAT");
	foreach ($lines as $line) { 
		$data[$key] = explode("|", $line);

		$number = str_replace(' ', '', $data[$key][7]);
		$searchb = str_replace(' ', '', $_POST['c']);
		if (preg_match("/$searchb/i", $number)) {

		print "match.<br />";
		}

		}

 

Thanks in advance!

change

if (preg_match("/$searchb/i", $number)) {

to

if (preg_match("/^$searchb/i", $number)) {

Thank-you so much.

 

What does the ^ mean?

[MadTechie]

in this case (being at the very start) ^ means starts with

 

but don't get confused with [^123] which would mean exclude 1,2 & 3

If say I wanted to search both of the following:

 

$number = str_replace(' ', '', $data[$key][9]);
$numberb = str_replace(' ', '', $data[$key][11]);

 

How would I incorporate that into preg_match?

 

if (preg_match("/^$searchb/i", $number, $numberb)) {

 

Is that correct?

[MadTechie]

do you mean

$number AND $numberb

or

$number OR $numberb

an examples would help

[Schlo_50]

Number AND Numberb please.
