PHP - Best Way To Store "friends" In A Database?

I am getting the following error when using composer: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"?

Just started.  I am pretty sure composer.json wasn't changed.  journalctl doesn't show anything.  Maybe Doctrine related, however, nothing seems to help.

Any ideas?

"BACK" or REFRESH: Preventing database interaction / code execution
how to prevent database interaction / code execution when user presses back or refresh button?
can i detect?
can i disable back/refresh?

I've been trying to simplify this code, let alone make it work.  It's a loop to change the different question checkboxes to "checked" if certain degree_ids are found.  All of the examples i have looked at are very strange and I'm not sure how to go about this, thought it seems to be a common question.  Everyone seems to have their own way.  Any advice would be greatly appreciated.

for($i =1; $i <= $arraycount; $i++){
$query = "SELECT degree_id FROM `user-degree` WHERE `user_id` = '".$user_id."' AND degree_id = '".$i."'";
$result = $conn->query($query) or die(mysql_error());
$row = mysqli_fetch_array($result) ;

echo $row['degree_id'];

if(!$y){
$y = 0;
}

if ($row['degree_id'] == 1){
$q4[0] = 'checked';
}
if ($row['degree_id'] == 2){
$q4[1] = 'checked';
}
if ($row['degree_id'] == 3){
$q4[2] = 'checked';
}
if ($row['degree_id'] == 4){
$q4[3] = 'checked';
}
if ($row['degree_id'] == 5){
$q4[4] = 'checked';
}
if ($row['degree_id'] == 6){
$q4[5] = 'checked';
}
if ($row['degree_id'] == 7){
$q4[6] = 'checked';
}
if ($row['degree_id'] == 8){
$q4[7] = 'checked';
}
if ($row['degree_id'] == 9){
$q4[8] = 'checked';
}

I am currently creating a form and I want to populate a drop down selection menu with data from two fields in a form. For example, I want it to pull the first and last name fields from a database to populate names in a drop down menu in a form. I want the form to submit to the email address of the person selected in the drop down. Is this possible to do? The email is already a field in the record of the person in the database.

Can anyone give me some pointers or advice on how I should go about setting up the "Select" box drop down? I am not sure how to code it to do what I am wanting. Any links to relevant help would be appreciated too.

Thanks in advance!

Hello All,

I have a custom session.set_save_handler to handler sessions for my application. It seems to work fine. The database table is of type innodb. I see some errors in my log file of the nature, "(1205) Lock wait timeout exceeded; try restarting transaction".

I have a class which contains the session handler callbacks and have made it a singleton class.

 session_set_save_handler(
        array($this, "db_open"),
        array($this, "db_close"),
        array($this, "db_read"),
        array($this, "db_write"),
        array($this, "db_destroy"),
        array($this, "db_gc")
        );

In my "db_read" method, I am doing a "SELECT FOR UPDATE" on the row with the session id. So, while performing load testing on my app. which has a lot of ajax calls, I noticed the "lock wait timeout" errors.

How do I resolve this problem? Any suggestions?

1) Should I catch these errors and issue a explicit "commit" in the read or write methods?
2) Should I specify a higher timeout value for "innodb_lock_wait_timeout"?

Thanks

I am creating a new forum software known as Iforum, it will  use php and a database.

(I am good with php, html, and CSS but I am not great with databases
Any suggestions?

Hi, I currently have an if, elseif, else program that starts off with

Code: [Select]
if( $v_name == "" || $v_msg == "" )
echo "something"
how do I turn this into a switch?

but the very next elseif I have

Code: [Select]
elseif( strcspn( $_REQUEST['msg'], '0123456789' ) == strlen( $_REQUEST['msg'] ) )
echo "something"

is it possible to turn this into a switch with 2 different strings like that to evaluate?

I was wondering how to write something like this:

if (table1.column1 + table2.column2 > table3.column3  then .....

I am confused where to put ( ) and '

If I run this:
mysql_query("CREATE DATABASE IF NOT EXISTS `{$this->db['db']}`", $this->tdb);

Will mysql_query() return true or false if the database already exists?

I can not run this on my server due to permissions.

Hey guys!
I have the following doubt:

I have a php file that does the following alongside with other code not displayed he

$fp = fopen("emails.txt", "w");

It opens a txt file called emails.txt that is in the same folder where the php is saved but how do I tell $fp = fopen("/folderbefore/emails.txt", "w"); ??

In other words, how do I write the path on the script that the emails.txt is located in a previous folder where the php file is located??

Thanks in advance for your help
Cheers!
