PHP 5.5 - try, catch and finally psedocode

gistfile1.txt

lock tables

// attempt to write to the database, then unlock the tables.

try {
  writing to db
  unlock tables
}
catch exception {

If there’s a problem, report the problem and unlock the tables. Notice that I have to manually unlock the tables in both steps.

  report problem
  unlock tables
}

In 5.5, a new block is now available, called “finally”. Finally executes after a try/catch block and before normal execution resumes, which allows cleanup operations to be run even if there was a problem.

Here’s how the same functionality would look in PHP 5.5, with less redundant code.

lock tables
try {
  writing to db
}
catch {
  report problem
}
finally {
  unlock tables
}
