I was hoping that the timeout of 10 (seconds?) would force the Curl call to terminate. The code is listed below: 'Parameter 1') I tried using a curl_error, but no success. I have not used try catch statement much, and I wanted to know how to return values in a try catch statement. While that is not LITERALLY reversing your execution, it does exactly the same effect without risking a goto.How do I make a retry of three attempts on a failed PHP Curl call? I notice that my code seems to stop working. try and catch in PHP - should I return in the 'try' block Ask Question Asked 10 years, 4 months ago Modified 4 years, 9 months ago Viewed 7k times Part of PHP Collective 14 Below is my try catch statement in a function. (The variable was required prior to PHP 8.0.0.) The first catch block a thrown exception or error encounters that matches the type of the thrown object will handle the object. In php, after a bit of trial and error, I now use nested try while($resuming). A catch block defines one or more types of exception or error it can handle, and optionally a variable to which to assign the exception. If you have access to your php.ini file, you can go in there and add displayerrors on and that should allow you to see what errors your PHP code is throwing. That is what it actually does Hanky Panky. As for the 500 error, thats probably appearing because PHP errors are turned off on your server. Well if there was no way to do that then there would be no point of a try-catch block. If I were you I would use an ordinary for-loop with an iterator. It is designed to give you the next item in the iterator. The result of this is I still get the context of the original error, even though it was thrown at the top.Īnother option might be to return a custom NullObject or a UnknownProperty object and compare against that before deciding to trip the catch(), but as you can re-throw errors anyway, and if you're fully in control of the overall structure, I think this is a neat way round the issue of not being able to continue try/catches.Īn old question, but one I had in the past when coming away from VBA scipts to php, where you could us "GoTo" to re-enter a loop "On Error" with a "Resume" and away it went still processing the function. Since a short period of time Im working with Try Catch in PHP. I dont think that you can with a foreach. if we get here, $result was valid, or ignored Throw($result) // throw the original error if the result is an error, choose what to do with it this function will pass back a value, or a TemplateExecption if invalid If no catch block is found, the CLR terminates the executing thread. If the currently executed method doesnt contain such a catch block, the CLR looks at the method that called the current method, and so on up the call stack. Catching the base exception type and swallowing it is a bad practice in any language, PHP or otherwise. When an exception is thrown, the common language runtime (CLR) looks for the catch block that can handle this exception. But the example you give has less problems with do/while and more with swallowing exceptions in the try/catch block. For each try block in a PHP program, there should be a minimum of one catch block. Such exceptions are caught with PHP catch block. And, try block contains code with the feature of PHP exception handling by throwing exceptions that occurred while executing PHP scripts. Then, in the calling code, I can decide whether to throw this returned error, causing the try() to catch(), or just continue: // process the template There is no reason to avoid mixing try/catch with do/while. PHP MYSQL UPDATE not working 3 need help in. PHP try-catch is implemented with try and catch blocks, as usual. Lets quickly go through the basic exception handling flow, as shown in the following pseudo-code. You are responsible for throwing exceptions when something occurs which is not expected. If the user attempts to access a property that doesn't exist on the data, I return the error from deep within the processing function, rather than throwing it. Exceptions can be thrown and caught by using the PHP try and catch blocks. I needed to do this with a templating framework I'm writing. Another angle on this is returning an Exception, NOT throwing one, from the processing code.
