Include these methods into my class - php

Question

These are my two methods, I need to include them in my class but am unsure how to do it since I'm not an OO programmer
function gcd($x,$y)
{
do {
$rest=$x%$y;
$x=$y;
$y=$rest;
} while($rest!==0);
return $x;
}
function testCommonality($a)
{
$keys = array_keys($a[1]);
$common = array();
foreach ($keys as $key) {
$v1 = $a[0][$key];
$v2 = $a[1][$key];
if ((gcd($v1, $v2)) != 1) $a[0]['m'] *= 1.5;
}
return $a;
}
print_r($parser->algorithm->testCommonality());
I need to include those in this class, and have them operate on the output of $parser->algorithm Help is greatly GREATLY appreciated
class CSVParser
{
public $output = NULL;
public $digits = NULL;
public function __construct($file)
{
if (!file_exists($file)) {
throw new Exception("$file does not exist");
}
$this->contents = file_get_contents($file);
$this->output = array();
$this->digits = array();
}
public function parse($separatorChar1 = ',', $separatorChar2 = ';', $enclosureChar = '"', $newlineChar = "\n")
{
$lines = explode($newlineChar, $this->contents);
foreach ($lines as $line) {
if (strlen($line) == 0) continue;
$group = array();
list($part1, $part2) = explode($separatorChar2, $line);
$group[] = array_map(array($this, "trim_value"), explode($separatorChar1, $part1), array("$enclosureChar \t"));
$group[] = array_map(array($this, "trim_value"), explode($separatorChar1, $part2), array("$enclosureChar \t"));
$this->output[] = $group;
}
}
private function trim_value($value, $chars)
{
return preg_replace("#^( |" . $chars . ")+#", '', $value);
}
public function algorithm()
{
$alpha = array(
'c' => str_split('bcdfghjklmnpqrstvwxz'),
'v' => str_split('aeiouy')
);
$i = 0;
$k = 0;
foreach ($this->output as $item) {
$cnt = 0;
$this->digits[$i] = array();
foreach ($item as $part) {
$this->digits[$i][$cnt] = array();
$new = array();
foreach ($part as $str) {
$v = count(array_intersect(str_split($str), $alpha['v']));
$c = count(array_intersect(str_split($str), $alpha['c']));
$t = strlen(str_replace(' ', '', $str));
$new = array('v' => $v, 'c' => $c, 't' => $t);
$this->digits[$i][$cnt][] = $new;
}
$cnt++;
}
$i++;
}
}
}
$parser = new CSVParser("file.txt");
$parser->parse();
print_r($parser->output);
$parser->algorithm();
print_r($parser->digits);
Thanks for the help!

I know very little of PHP, but, if I understand correctly, what you are asking appears to be straight forward enough. I would have thought somebody would have already answered this.
The following may be something like what you are after:
class CSVParser
{
public $output = NULL;
public $digits = NULL;
public function __construct($file)
{
if (!file_exists($file)) {
throw new Exception("$file does not exist");
}
$this->contents = file_get_contents($file);
$this->output = array();
$this->digits = array();
}
public function parse($separatorChar1 = ',', $separatorChar2 = ';', $enclosureChar = '"', $newlineChar = "\n")
{
$lines = explode($newlineChar, $this->contents);
foreach ($lines as $line) {
if (strlen($line) == 0) continue;
$group = array();
list($part1, $part2) = explode($separatorChar2, $line);
$group[] = array_map(array($this, "trim_value"), explode($separatorChar1, $part1), array("$enclosureChar \t"));
$group[] = array_map(array($this, "trim_value"), explode($separatorChar1, $part2), array("$enclosureChar \t"));
$this->output[] = $group;
}
}
private function trim_value($value, $chars)
{
return preg_replace("#^( |" . $chars . ")+#", '', $value);
}
public function algorithm()
{
$alpha = array(
'c' => str_split('bcdfghjklmnpqrstvwxz'),
'v' => str_split('aeiouy')
);
$i = 0;
$k = 0;
foreach ($this->output as $item) {
$cnt = 0;
$this->digits[$i] = array();
foreach ($item as $part) {
$this->digits[$i][$cnt] = array();
$new = array();
foreach ($part as $str) {
$v = count(array_intersect(str_split($str), $alpha['v']));
$c = count(array_intersect(str_split($str), $alpha['c']));
$t = strlen(str_replace(' ', '', $str));
$new = array('v' => $v, 'c' => $c, 't' => $t);
$this->digits[$i][$cnt][] = $new;
}
$cnt++;
}
$i++;
}
return $this->digits;
}
private function gcd($x,$y)
{
do {
$rest=$x%$y;
$x=$y;
$y=$rest;
} while($rest!==0);
return $x;
}
public function testCommonality($a)
{
$keys = array_keys($a[1]);
$common = array();
foreach ($keys as $key) {
$v1 = $a[0][$key];
$v2 = $a[1][$key];
if ((gcd($v1, $v2)) != 1) $a[0]['m'] *= 1.5;
}
return $a;
}
}
$parser = new CSVParser("file.txt");
$parser->parse();
print_r($parser->output);
$parser->algorithm();
print_r($parser->digits);
print_r( $parser->testCommonality( $parser->digits() ) );
