Why do you presume this is "hearsay PHP hatred"? I (not parent) have PHP hatred. It is fuelled by decades of PHP development and -exposure. My hatred is based on failing projects, missed deadlines, burnouts, money stolen, severe downtime, and companies going bankrupt. PHP had a role (not the primary, mind you!) in all of them.
It had a role because PHP is the most used web technology in the world.
I'll admit that in all cases, the humans involved where the actual root cause, but that is silly, because it always is. What PHP lacked in all these cases, was guidance, support or limitations to direct these humans to better architecture, or guide them away from bad decisions.
I'm not disliking PHP for silly designs inconsistencies, or hard-to-deprecate insecure functions. I'm disliking it for how it has taught generations of developers to not care about quality, to avoid software design and architecture, to work around hacks, to ignore failing tests, to "it's not a bug, its documented", etc.
To take a more famous, public example: MtGox, the primary Bitcoin Exchange, was hacked, BTC crashed, millions were stolen. Because adversaries breached a poorly written PHP backend service. Yes. MtGox was a bitcoin exchange moving millions a day, written in mostly PHP.
