PHP7: Unable to load dynamic library 'intl'

Question

I'm trying to upgrade my wamp server from php5 to php7 (I know I'm a little behind times) and on server startup I'm getting this error

PHP Startup: Unable to load dynamic library 'intl' (tried: C:\PHP73\ext\intl (The specified module could not be found.), C:\PHP73\ext\php_intl.dll (The specified module could not be found.)) in Unknown on line 0

I've tried searching various places on the web for an answer, but nothing seems to work.

I have apache 2.4 and php 5.6 installed and working and I'm trying to upgrade to php 7.2. I've completely commented out all references to php5 in apache httpd.conf and replaced it with php7

#LoadModule php5_module "C:/PHP56/php5apache2_4.dll"
LoadModule php7_module "C:/PHP72/php7apache2_4.dll"
...
#PHPIniDir "C:/php56"
PHPIniDir "C:/php72"

I have my php extensions in C:\PHP72\ext, and the dll file is in there:

C:\PHP72\ext>dir
Volume in drive C is TAFO
Volume Serial Number is 0C3B-1BE9

Directory of C:\PHP72\ext

01/09/2019  02:58 PM           108,032 php_mysqli.dll

I'm referencing the full path in the php.ini:

extension_dir = "C:\\PHP72\\ext"

Yet whenever I restart or start the server I get the "Unable to load dynamic library" message. I am using functions from the intl library so I can't just comment it out. All the other modules are loading fine.

How can I fix this, or even know why it isn't loading? Thanks.

Answer 1

Fixed my own problem. After hours of hacking at this I realized that I forgot to add the php7 path to my system variables. Adding that and restarting my computer fixed it.
