I am attempting to clean up my URLS in the database, however I am literally having a brain-fart. This is PHP 101 level stuff, but I seriously cannot figure out what’s wrong with the following snip:
<?php $domain = 'http://www.example.com'; echo "nne[31mBeginning Domain is: $domainn"; if (strpos($domain, '//')){ $domain = explode( '//', $domain)[1]; echo "ne[33mRemoving HTTPn"; } echo "nne[35mAfter first IF domain is: $domainn"; if (strpos($domain, "www.")){ echo "ne[33mREMOVING WWWn"; $domain = explode( "www.", $domain)[1]; } echo "nne[35mAfter second IF domain is: $domainn"; die("nne[31m$domainnn");
When run .. I am expecting a “clean” example.com
— However my output looks like:
Beginning Domain is: http://www.example.com Removing HTTP After first IF domain is: www.example.com After second IF domain is: www.example.com www.example.com
Why is if (strpos($domain, "www.")){
not entering the if
?

Answer
Why not debug the code properly? strpos($domain, "www.")
returns 0
as long as $domain
starts with www
, and that evaluates to false
.
By properly checking whether strpos($domain, "www.")
returns exactly false
, you can fix your algorithm
