How to supprest PHP warning?

Question

0.00/5 (No votes)

See more:

The warning is:
PHP Notice: Array to string conversion
When encountering an array instead of a string, implode function replaces "Array" and this is enough for me. So, the output of the function is as I want. I just want it not to issue a warning message in error.log.
How to suppress it?

details:
as an example when i run the following code:

PHP

#!/usr/bin/php

<?php
$ar = array(0, array(0, 1), 1);
$str = implode(', ', $ar);
error_log($str);
?>

i get the following output:

PHP Notice:  Array to string conversion in /home/behnama/test/php/implode.php on line 5
0, Array, 1

my question again is: how can i suppress the error message while the output is as i expect?

What I have tried:

I searched for it everywhere and found no clue.

Please edit your question and add the code that raises the error, and post the exact message and explain when it occurs.

In order to remove the secret warning, you have to do a secret correction in your secret code.

sorry, i thought it was clear enough. now i've updated it with an example.

Why would you think it is clear if we cannot see your code or the complete message? Those are the two most important pieces of information.

I just ran that code and did not receive the message.

so maybe something is different in php config file(s)?

You can reproduce it for example by pasting it in http://phptester.net/

NOTICE Array to string conversion on line number 5

what is your expected output?

ilostmyid2 9-Jun-18 10:36am

the line below it:
0, Array, 1

My suggestion would be, do not change warning level. Instead add @ at the begining of the fuction.

Since your question is specifically to suppress the error message, rather than fix the issue, you could use error_reporting to turn off notices:

error_reporting(E_ALL & ~E_NOTICE);

I wouldn't recommend it, but you can do it if you want to.

thx, looked for this.
after implode, i may call the function again:
error_reporting(E_ALL);
so that other errors won't be suppressed.
but essentially why this should have been an error?!...

It's not actually an error, just a notice :)
It informs you that the sub-array array(0, 1) was converted to the string as "Array", which might be unexpected.

ilostmyid2 9-Jun-18 10:48am

i expect it anyway... :)
