php – short_open_tag not working?

September 9, 2018Apache, PHPpjrfigueiredo

Some tutorials tell use to set short_open_tag on /etc/php.ini, but it might now work!
This might not be the php.ini that PHP/Apache is reading.

Use phpinfo() to get the real php.ini file.

Hope it helps anyone.

PEAR – DB Error: extension not found

September 8, 2018Linux, PHPmysqli, pearpjrfigueiredo

Yesterday I had to set up a new server for bunch of sites from 2008 using PHP Pear….

You might need to add the following line at the end of /etc/php.ini

extension=mysqli.so

codeigniter + php + mysql – emojis 😉

July 6, 2018CodeIgniter, MySQL, PHPpjrfigueiredo

This is how…

On mysql set your table(s)’s filed(s) to utf8mb4_general_ci.

codeigniter config/database.php

$db['default']['char_set'] = 'utf8mb4';
$db['default']['dbcollat'] = 'utf8mb4_general_ci';

PHP Parse error: syntax error, unexpected end of file in

October 25, 2017Apache, CentOS, PHPpjrfigueiredo

I had a script working perfectly on a server…
after moving it to another, I got PHP Parse error: syntax error, unexpected end of file.

In my case, I had to allow short_open_tag to ON in php.ini … probably located at /etc/php.ini.

php & json – Chinese characters

July 9, 2017PHP, Sh*tschinese, json, utf8pjrfigueiredo

I’m working on a site, who has a bunch of translations.
We wanna have chinese on it, ’cause its an “emerging” market for our biz market.

This will work!

$translations = file_get_contents(getcwd().'/json/translations.json');
$translations = json_decode($translations, JSON_UNESCAPED_UNICODE);

PHP 5.6 on CentOS 7

March 9, 2017CentOS, PHPcentos, php, php56pjrfigueiredo

This is how I managed to have PHP 5.6 on a fresh CentOS 7.

yum install epel-release
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
yum clean
yum update

Then…

yum install php56w php56w-opcache php56w-mcrypt php56w-pdo php56w-mysql php56w-mbstring php56w-gd php56w-dom

ImageMagick

yum install ImageMagick php56w-imagick

Restart httpd

service httpd restart

PHP – It is not safe to rely on the system’s timezone settings.

March 8, 2017CentOS, PHPdate, timezonepjrfigueiredo

Edit php.ini, mine, on CentOS 7 is located at /etc/php.ini.
Lets add the following line.

date.timezone = America/New_York

For other timezone take a look at http://www.php.net/manual/en/timezones.php

and then restart httpd

service httpd restart

If you don’t have access to the php.ini, here is another way to do it.
On our app/php…

if(!ini_get('date.timezone'))
{
    date_default_timezone_set('GMT');
}

as seen on http://stackoverflow.com/questions/16765158/date-it-is-not-safe-to-rely-on-the-systems-timezone-settings
