I still remember how this started.
Facebook. Opera Mini. A Nokia E75.
A tiny screen, a slow connection, and one small thing that changed everything: ".php" flashing past for a second.
I had watched The Social Network around that time. It made the whole thing feel real. Maybe people actually did build something from nothing. Maybe this was not just for other people.
So I looked it up.
That was when I found out PHP was written in C.
To my younger self, the next step seemed obvious: learn C, understand what was behind PHP, and get there somehow.
Then I started.
C was not just another language to me. It was a different world. Pointers. Memory. Low-level thinking. And behind PHP, the Zend Engine.
I had no idea how much I did not understand.
I kept trying anyway.
And I failed.
That is the truth. I was frustrated, lost, and angry at myself. Some days it felt as though I was chasing something that did not even want me.
Looking back, I was not failing because I was dumb. I was trying to force my way through ideas I did not understand yet. That was frustrating as hell.
Then 2020 came, and everything got quiet.
In that silence, I had to face something: the path I was taking was not working for me.
I changed direction.
I left my job with nothing in my pocket. No degree. No safety net. Just questions from people, from family, and from myself.
And I kept going.
I learned PHP properly this time. I could build things. I could see progress. I could feel myself moving.
By 2023, there was freelance work. Then a corporate job. Then Laravel.
There was no magic moment when everything became easy. There was work, and there was showing up again, including the days when I doubted myself.
Learning to build applications gave me a way to keep moving. It did not make the original curiosity disappear.
On April 6, 2026, my pull request to php/php-src was merged.
The change was in the SNMP extension: promoting invalid-input warning paths to ValueError. It covered malformed IPv6 hosts, missing type or value entries in OID arrays, and invalid contextEngineID values, with corresponding test updates.
That is a specific, bounded change. I did not rewrite PHP.
But my code was in its source.
For someone reading the diff, it might be a small contribution. For me, it carried years.
It carried that kid scrolling Facebook on a small phone, wondering how a page worked. It carried the failed attempts and the moments when I thought maybe I was not built for this.
You do not have to understand the entire engine before building your first useful thing.
Changing the route does not mean giving up on the destination. Sometimes it gives you the experience you were missing.
Start with a problem you can reproduce. Make the example smaller. Read the surrounding code. Write the test. Accept the review. Try again.
I wish I had understood that earlier. But I cannot separate this moment from the years it took to reach it.
More than a decade after the curiosity began on Facebook, I had a merged PHP contribution to share there.
That kid actually fucking did it.
And I am still getting started.
September 13, 2026 · PHP
A spare-parts import receives the code " ax-204 ". The database expects "AX-204". This small example is a good place to understand the pipe operator before putting it into a much larger import.
Save this as pipe.php and run it with PHP 8.5 or newer. The version matters: an older PHP parser cannot understand this syntax.
<?php
$incoming = " ax-204 ";
$code = $incoming
|> trim(...)
|> strtoupper(...);
assert($code === 'AX-204');
echo $code, PHP_EOL;
Each stage receives the preceding value. The three dots create a callable; they do not execute the function immediately. Expected output: AX-204. This is a transformation of a known string, not input validation.
A function needing more than one argument needs an adapter. Parentheses around an arrow function are required here.
<?php
$label = " ax-204 "
|> trim(...)
|> (fn (string $value) => str_replace('-', '/', $value))
|> strtoupper(...);
assert($label === 'AX/204');
echo $label, PHP_EOL;
In this example the supplier changes separators, so the adapter owns that specific rule. Keeping it visible prevents an unexplained replacement from hiding inside a general-purpose helper.
I would keep database writes, network requests, and error recovery outside this particular chain. If the supplier sends an array, validate the payload and reject it before these string operations. If codes are case-sensitive, remove the uppercase stage entirely. A convenient language feature cannot decide the supplier's identifier contract.
Run the example with an empty string, a code containing two hyphens, and a value already normalized. Decide separately whether each result is acceptable. Passing the transformation test does not mean an empty code may be inserted into the catalog.
The operator is already part of PHP 8.5; it is not an upcoming PHP 8.6 feature. PHP's functional operator reference documents callable requirements and arrow-function parentheses.
