> it was never the language
That's just, not correct. I programmed web sites primarily in PHP back in the PHP3-5 days (and have had some jobs and contracts since, in PHP7+).
PHP, pre-5.3ish, was a bad language. It had terrible design decisions, a polluted global space, bad default configurations, weird scoping rules, function/objects with massive security holes that the developer had to patch around (the MySQL functions, being notorious) and a terrible object model. PHP5-5.3 did a lot to fix that, and 5.3+ became a usable language. PHP7 finally did a ton of work to clean up the global environment, deprecate and toss out old/buggy libraries, clean up the ABI and improve performance. They also reworked the object model completely. It is now a genuinely decent language. But it was not "always great".
