php - I can't add IPs to my database. Why? -


so want able add different ips database. is:

if ($stmt = $conn->prepare("update csgo_servers set ips = ips + '$anip' + '|' id = ?")) {     $stmt->bind_param("s", $id);     $stmt->execute();     $stmt->close();     echo "ip added!"; }

i want have different ips in longtext column that: 32.12.53.12|42.12.41.2|42.1.6.3.7. problem when it adds first let's 32.12 of ip , without |. help?

structure of table
mentioned in comments, having character-separated values in database (in case, separator |), bad idea. should normalize database - have more rows instead of doing that. it'll way easier work with!

why won't work is
mysql can't add strings + (like in javascript). that's telling mysql want mathematics (adding integers, e.g 1+1). means you're silently converting integers, why you're seeing first part of ip (the first part before period . integer, rest turnicated).

solution
can use concat() function achieve want - although mentioned above, i advise against structure, add last ip separator |.

with adding new ip bounded placeholder (like bind id), new code this. should bind every variable going query, otherwise it's little pointless. 

if ($stmt = $conn->prepare("update csgo_servers set ips = concat(ips, '|', ?) id = ?")) {     $stmt->bind_param("ss", $anip, $id);     if ($stmt->execute())         echo "ip added!";     $stmt->close(); }

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
