If value exists in array, end, and restart with next array value - php

Question

All day I've been trying to achieve the following with PHP:
Update: This is the code I'm using, please read the message in between
<?php
include ('acs_params.php');
$acs_value_based = array(25, 30, 35, 40, 45, 50, 60, 70);
$acs_types = array("$add_total","$done_total");
print_r($acs_id);
foreach ( $acs_value_based as &$value ) {
foreach ( $acs_types as &$counters) {
if ($counters >= $value) {
if ($acs_types[0] == $counters) {$acs_types1 = '1'; $acs_name = 'Tasker'; $acs_action = 'adding';}
if ($acs_types[1] == $counters) {$acs_types1 = '2'; $acs_name = 'Completer'; $acs_action = 'completing';}
if ($value == '25') { $acs_lvl = '1'; $acs_id = '25';}
if ($value == '30') { $acs_lvl = '2'; $acs_id = '30';}
if ($value == '35') { $acs_lvl = '3'; $acs_id = '35';}
$acs_exists = $acs_types1 . $acs_id;
Over here it should check if this array print_r($acs_id); contains the value of
$acs_exists. if the value already exists the following code should not be executed,
instead, the script should start again at the beginning but then with the second value of
the array print_r($acs_id);. It the value is not existing yet, then continue with the queries. (I hope my goal is clear).
mysql_query("INSERT INTO users_log(id, log, userid, date, points, action) VALUES
(id, 'achievement 1', '$username', '$currenttime', '0', '8') ");
mysql_query("INSERT INTO users_achievements(id, userid, acs_id, date) VALUES
(id, '$username', '$acs_types1$acs_id', '$currenttime') ");
?>

Answer 1

foreach ($acs_id as $item) {
if ($item == $acs_exist) continue;
// continue with the script (query etc)
}
Is that what you're after?

Answer 2

This sounds to simple, but I'll give it a shot:
// if $acs_exist is not in the array $acs_id, execute script, otherwise do nothing
if(!in_array($acs_exist, $acs_id)) {
// do whatever you want
}
I'm still poking in the dark here …
foreach($acs_id => $id) {
if($acs_id == $acs_exist) { // already exists
} else { // does not exist yet, insert into db
// your code: INSERT INTO table (column, …) VALUES(:acs_id, …)
}
}
