Example of simple exception handling class implemented by PHP

This article describes the simple exception handling class implemented by PHP. Share it for your reference, as follows:

&lt;?php
header('content-type:text/html;charset=UTF-8');
// Create an email exception handling classclass emailException extends exception
{
}
// Create pwd exception handling classclass pwdException extends exception
{
  public function __tostring(){
    return $this-&gt;getMessage().'in file:'.$this-&gt;getFile().'on line:'.$this-&gt;getLine();
  }
}
function reg($reginfo = null)
{
  // Throw different exceptions according to different errors  if (empty($reginfo) || !isset($reginfo)) {
    throw new Exception('The parameter is illegal');
  }
  if (empty($reginfo['email'])) {
    throw new emailException('The email is empty');
  }
  if ($reginfo['pwd'] != $reginfo['repwd']) {
    throw new pwdException('The passwords were inconsistent twice!  ');
  }
}
// Receive different exceptions and handle them in a targeted manner!try {
  reg(array('email' =&gt; '1078789950@', 'pwd' =&gt; '123', 'repwd' =&gt; '1231' ));
} catch (Exception $e) {
  echo $e -&gt;getMessage();
} catch (emailException $ee) {
  echo $ee -&gt;getMessage();
} catch (pwdException $ep) {
  echo $ep;
}
