Finding part of a string from arrays values and parsing values that contain them

[john_doemoor]

So my issue is, that i have this function:

	public function parseLogLines($logLines, $householdId) {
	$logLinesArray = array();
	foreach(preg_split("/\n|\r/", $logLines) as $logLine) {
		if (preg_match("/$householdId/", $logLine) > 0) {
			$logLineArray = preg_split("/,/",$logLine, 2, PREG_SPLIT_NO_EMPTY);

			$index = (int)$logLineArray[0];
			$content = $logLineArray[1];
			$logLinesArray[$index] = $content;
		}		
	}
	return $logLinesArray;
}

which goes thru loglines and if they match stores them to array.

then i have this function:

	public function getUserLogLines($logLines, $householdId) {
	$this->userLogLines = $this->userLogLines + $this->parseLogLines($logLines, $householdId);

	return $this->userLogLines;
}

which goes thru new log entries and remembers them.

 

How can i make that last function to find a part of a string from value?

Other issue is how to make the first function to parse also those loglines which include the part of string parsed from value?
