 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

so i really go crazy and i dont know what to do now ?! the thing i dont want to the the most is "remove all and install from scratch" as i said i got a working system with lots of sites involved, so if you have any idea let me know, sure i tried restarting httpd

i know i probably did not provide all required information but i didnt want to tldr;

after all php -m | grep image php -m | grep image

returns nothing

heres the full output of php -m

Answer 1

Just disable remi-test (which have some 5.6 packages, so create conflicts).

yum-config-manager --disable remi-test
yum install php-pecl-imagick

BTW 5.5 is now EOL , so I strongly recommend you update to a maintained version .

php55-php-pecl-imagick is an SCL package for multiple versions installed simultaneously, you probably don't need this.

See the Wizard instructions .
