Zabbix 1.8 MBstring?

[mucknet]

I'm trying a new install of zabbix 1.8, and during the pre requesite check, I'm getting a failure of: PHP MB String support

I was also getting a failure of PHP MB String overload until I changed php.ini to include: mbstring.func_overload = 2

I'm on CentOS 5.3, and in installed php-mbstring. Any suggestions on what I need to change to get zabbix to detect it?

[root@admin3-test zabbix]# rpm -qa | grep php
php-pdo-5.1.6-23.2.el5_3
php-cli-5.1.6-23.2.el5_3
php-mysql-5.1.6-23.2.el5_3
php-gd-5.1.6-23.2.el5_3
php-mbstring-5.1.6-23.2.el5_3
php-common-5.1.6-23.2.el5_3

I'm having this same problem, also with CentOS. Everything tells me that mbstrings is installed and enabled, but the pre-req check won't clear me for takeoff.

Same problem

Its a problem with 2 functions, i'm comment them in:
grep "mb_" zabbix/include/locales.inc.php function_exists('mb_strlen') &&
function_exists('mb_strtoupper') &&
function_exists('mb_strpos') &&
function_exists('mb_substr'); # &&
# function_exists('mb_stristr') &&
# function_exists('mb_strstr');

And zabbix setup was done without problem.
I can't explain this - may be developers could?

I commented out the entry in include/setup.inc.php which worked and got me past the installation screen.

I confirm this problem. The problem exists only for PHP 5.0.x and 5.1.x. PHP 5.2 and later versions will work fine.

Removing or commenting these two lines is absolutely correct workaround as these functions are not used anywhere in the front-end.

Sorry for this problem.

As documentation says PHP version 5.2 or later is required.

How to install PHP 5.2.6 on Centos 5.3 ?

[root@zabbix ~]# rpm --import http://dev.centos.org/centos/RPM-GPG-KEY-CentOS-testing
[root@zabbix ~]# cd /etc/yum.repos.d
[root@zabbix ~]# wget http://dev.centos.org/centos/5/CentOS-Testing.repo
[root@zabbix ~]# yum --disablerepo=* --enablerepo=c5-testing update php

As documentation says PHP version 5.2 or later is required.

Zabbix 1.8 requires PHP 5.0 or later. The documentation is not correct, we will review and fix it shortly.

Yes, I'm use PHP 5.1.6.

mbsring.func_overload

Zabbix 1.8 requires PHP 5.0 or later. The documentation is not correct, we will review and fix it shortly.

Web frontend installer checks "mbstring.func_overload 2" in php.ini file.
Then, strstr and stristr function is overloaded by mb_strstr and mb_stristr.

I checked source code.

- strstr function is not used
- stristr function is used in include/db.inc.php only

case 'ORACLE':
        if(ocifetchinto($cursor, $row, (OCI_ASSOC+OCI_RETURN_NULLS))){
                $result = array();
                foreach($row as $key => $value){
                        $field_type = strtolower(oci_field_type($cursor,$key));
                        $value = (str_in_array($field_type,array('varchar','varchar2','blob','clob')) && is_null($value))?'':$value;

                        if(is_object($value) && ([B][COLOR="red"]stristr[/COLOR][/B]($field_type, 'lob') !== false)){
                                $value = $value->load();
                        }

                        $result[strtolower($key)] = $value;
                }
        }
        break;

mb_strstr and mb_stristr function is include PHP 5.2 or later.
