fopen() error handling

Question

I'm working on a script at the moment that reads in an HTML template file, populates it with data and then saves the populated HTML file as a cached copy in my cache folder.

I'm having real difficulties evaluating whether an error has occured with fopen() while runtime errors are suppressed:

$file = @fopen($location,"w+"); 

// manual states fopen() returns false on error
// though the below does not catch any errors 

if (!$file) {
    $this->doSomething();
}

Is the suppression working against me? I would really appreciate some insight into this. I have tried setting error_reporting to display no errors,

ini_set('display_errors',0);
ini_set('log_errors',1);
error_reporting(E_ALL);

and removed the supression from fopen() but to no avail.

Answer 1

You code should work. If you never enter the if statement and no errors are triggered, the file was opened successfully. Why are you sure that the fopen() call failed?
