How we fix CodeIgniter a PHP error was encountered

Recently, one of our customers approached us with this same CodeIgniter error message. Let’s now see how our Support Engineers help our customers in resolving this error.

Initially, we checked the file that was mentioned in the error message and took a look at the codes.

We then could see that the Query Builder Pattern was incorrectly added. It was in the below pattern.

$query = $db->table->get['table_name'];

We then updated the Query Builder Pattern as below.

$query = $db->table->get('table_name');

This finally, fixed the error. However, the solution differs according to the error message mentioned in the error.

Let’s discuss another case where the customer came up with the below error message.

A PHP Error was encountered
Severity: Notice
Message: Use of undefined constant user_array - assumed ‘user_array’
Filename: xxx/xxx.php
Line Number: x

Here we added a $ symbol at the beginning of the variable name. This fixed the issue.

Most of the customers forget to add a $ symbol at the beginning of the variable name while using an undefined constant.

How we solved CodeIgniter a PHP error was encountered

To fix this error, you have to analyze and follow the error message to get a solution. In a recent experience with one of our client’s application, we observed that a wrong SQL code was imputed in the SQL Query Box. Take a look at this sql pattern;

$query = $db->table->get['table_name'];

You will see that there is an error in the use of box brackets instead of round brackets.

To fix this issue, use the correct format below;

$query = $db->table->get('table_name');

In another case, a client kept getting the following error message;

A PHP Error was encountered
Severity: Notice
Message: Use of undefined constant user_array - assumed ‘web_array’
Filename: directory/filename.php
Line Number: 12

By mere observing the code, you will see the constant web_array is not in the correct variable form.

To fix this we simply put an «$» symbol as a prefix to get a defined constant ($web_array).
