This is in fact an PHP 7.3 upgrade compatibility with older PHP scripts.
This is a quick fix for CodeIgniter.
Message: The each() function is deprecated. This message will be suppressed on further calls
Filename: core/Security.php | Line: 272
Quick fix
On line 272, of file application/system/core/Security.php there should be an ‘while’ with a ‘each’.
Make the following changes
//while (list($key) = each($str))
foreach($str as $key=>$str_values)An uncaught Exception was encountered Type: ParseError Message: syntax error, unexpected end of file
I had a closing condition with
<?}?>
had to change to
<?php }?>
This is how I’v solved this issue, in a loop….
$this->load->library('image_lib', $resize_config);
if ( ! $this->image_lib->resize() )
{
echo $this->image_lib->display_errors();
exit();
}
$this->image_lib->clear();
$this->load->library('image_lib');
$this->image_lib->initialize($resize_config);
if ( ! $this->image_lib->resize() )
{
echo $this->image_lib->display_errors();
exit();
}
$this->image_lib->clear();
A CI application was returning me the following error, after the PHP been updated to 7.3.
I had to change a few lines at config/config.php
function __autoload($class)
{
if(strpos($class, 'CI_') !== 0)
{
@include_once( APPPATH . 'core/'. $class . EXT );
}
}
to
spl_autoload_register(function($class) {
@include_once ( APPPATH . 'core/'. $class . EXT );
});Try to load the database library!
On your application/config/autoload.php
$autoload[‘libraries’] = array(‘database’,’session’);
This is how…
On mysql set your table(s)’s filed(s) to utf8mb4_general_ci.
$db['default']['char_set'] = 'utf8mb4';
$db['default']['dbcollat'] = 'utf8mb4_general_ci';https://stackoverflow.com/questions/16828197/displaying-utf8-character-on-codeigniter
This is kinda it!
$this->db->or_like(array('sender' => $k, 'msg' => $k));As seen on http://stackoverflow.com/questions/23254305/multiple-like-clause-codeigniter
I was having a 500 Internal Server Error…
nginx logs were showing me the following
2016/03/17 12:09:32 [crit] 31488#0: *11192 open() "/var/lib/nginx/tmp/client_body/0000000005" failed (13: Permission denied), client: 84.91.XXX.XXX, server: host.com, request: "POST /trades_edit/edit_trade HTTP/1.1", host: "host.com", referrer: "https://host.com/trades_edit/125"
Solution?
chown -R www-data:www-data /var/lib/nginx
On a new deployment of a Codeigniter tool that I’v made, I got the following error, after installed it in more than 10 different servers… my own servers and clients…
Severity: Notice
Message: Only variable references should be returned by reference
Filename: core/Common.php
Line Number: 257
This only happens with PHP >= 5.6….
We need to tweak /system/core/Common.php Line number 257
Change this line from
return $_config[0] =& $config;
to
$_config[0] =& $config; return $_config[0];
I’v stopped using CodeIgniter for 7 months, but I maintaining a product that was developed under CI.
Today I’v got a error saying “MySQL server has gone away” after a long time PHP execution.
I’v managed to solve it by, on the model that was getting me the error, *reconnect* to the database .
Before the *command* i’v added $this->db->reconnect();
$this->db->reconnect();
$this->db->insert('photoGallery', $data);
return $this->db->insert_id();
Hope it helps anyone out there.
