Question print the name of variable

How can I pass the name of the variable inside a for statment
I have a script something like below:

classA=12
classB=14
classC=16
# classD = 20

all_class="classA classB classC"

for i in $all_class
do
echo $i = $($i) #<---- this one not work
#echo $i = $(echo $i) # <---- this one not work too
#echo classA = $classA # <----- it can pass the classA = 12
done

Also, how can i do if i don't know how many class will be there and i don't want to change the all_class value ?

IGNORE_USER_ABORT(3)							 1						      IGNORE_USER_ABORT(3)

ignore_user_abort - Set whether a client disconnect should abort script execution

SYNOPSIS
int ignore_user_abort ([string $value]) DESCRIPTION
Sets whether a client disconnect should cause a script to be aborted. When running PHP as a command line script, and the script's tty goes away without the script being terminated then the script will die the next time it tries to write anything, unless $value is set to TRUE PARAMETERS
o $value - If set, this function will set the ignore_user_abort ini setting to the given $value. If not, this function will only return the previous setting without changing it. RETURN VALUES
Returns the previous setting, as an integer. EXAMPLES
Example #1 A ignore_user_abort(3) example <?php // Ignore user aborts and allow the script // to run forever ignore_user_abort(true); set_time_limit(0); echo 'Testing connection handling in PHP'; // Run a pointless loop that sometime // hopefully will make us click away from // page or click the "Stop" button. while(1) { // Did the connection fail? if(connection_status() != CONNECTION_NORMAL) { break; } // Sleep for 10 seconds sleep(10); } // If this is reached, then the 'break' // was triggered from inside the while loop // So here we can log, or perform any other tasks // we need without actually being dependent on the // browser. ?> NOTES
PHP will not detect that the user has aborted the connection until an attempt is made to send information to the client. Simply using an echo statement does not guarantee that information is sent, see flush(3). SEE ALSO
connection_aborted(3), connection_status(3), Connection Handling for a complete description of connection handling in PHP. . PHP Documentation Group IGNORE_USER_ABORT(3)
