I am little confused with try catch concepts.
I have this code in PHP.
<?php
while (true) {
try {
foreach ($data as $message) {
$functionToCall = new functions();
$functionToCall->remove($data);
}
} catch (Exception $e) {
echo "This is inside catch";
echo 'Message: ' . $e->getMessage();
}
}
class functions
{
public function __construct()
{
$this->dbConnection = pg_pconnect("host = $hostname port=$port dbname = $database user = $username password = $password")
or die("Can't connect to database" . pg_last_error());
}
public function remove($data)
{
$query = "UPDATE table
SET isDeleted = true;
$res = pg_query($this->dbConnection, $query);
if (!$res) {
print_r(error_get_last());
throw new Exception(error_get_last(), 1);
}
}
}
I made a slight change with code to throw an exception I added
unset($this->dbconnection);
after
$query = "UPDATE table
SET isDeleted = true;
to throw an exception. Exception is thrown but My catch is not catching this exception.
How can I catch this error?
Thanks

Looks like a syntax issue if that's the actual code, try this edit:
public function remove($data)
{
$query = "UPDATE table SET 'isDeleted'= true";
$res = pg_query($this->dbConnection, $query);
if (!$res) {
print_r(error_get_last());
throw new Exception(error_get_last(), 1);
}
}
Notice the quote mark changes around: $query = "UPDATE table SET 'isDeleted'= true";
Your exception logic was being parsed as a string it seems.
Notice your code doesn't close the string on $query ...
$query = "UPDATE table
SET \"isDeleted\" = true;
$res = pg_query($this->dbConnection, $query);
if (!$res) {
print_r(error_get_last());
throw new Exception(error_get_last(), 1);
}
