php: catch exception and continue execution, is it possible?

Is it possible to catch exception and continue execution of script?

Solution 1:

Yes but it depends what you want to execute:

E.g.

try {
   a();
   b();
}
catch(Exception $e){
}

c();

c() will always be executed. But if a() throws an exception, b() is not executed.

Only put the stuff in to the try block that is depended on each other. E.g. b depends on some result of a it makes no sense to put b after the try-catch block.

Solution 2:

Sure, just catch the exception where you want to continue execution...

try
{
    SomeOperation();
}
catch (SomeException $e)
{
    // do nothing... php will ignore and continue    
}

Of course this has the problem of silently dropping what could be a very important error. SomeOperation() may fail causing other subtle, difficult to figure out problems, but you would never know if you silently drop the exception.

Solution 3:

Sure:

try {
   throw new Exception('Something bad');
} catch (Exception $e) {
    // Do nothing
}

You might want to go have a read of the PHP documentation on Exceptions.

Solution 4:

php > 7

use the new interface Throwable

    try {
        // Code that may throw an Exception or Error.
    } catch (Throwable $t) {
        // Handle exception
    }

echo "Script is still running..."; // this script will be executed.

Solution 5:

Yes.

try {
    Somecode();
catch (Exception $e) {
    // handle or ignore exception here. 
}

however note that php also has error codes separate from exceptions, a legacy holdover from before php had oop primitives. Most library builtins still raise error codes, not exceptions. To ignore an error code call the function prefixed with @:

@myfunction();
