That is, some hints, things, and playing with github.
See path-array.php
PathArray class - enables working on 'dot notation' like:
$exampleInputData = ['user' => ['name' => 'John', 'sex' => 'male'] ];
echo PathArray::get($exampleInputData, 'user.name');// (We can use different separators than '.')
Working example: https://3v4l.org/kYeN9
See typed-array.php
TypedArray class - A very simple implementation of 'typed array', like this:
$stringArray = new TypedArray('string');
and now only strings can be added to the above $stringArray. Works with objects as well.
More examples below the class.
Ah, and here is a working example: https://3v4l.org/kHocv (can be outdated though)
See check-stuff.php
Overcomplicated script checking your PHP's error logging configuration. just copy and paste the above code to some file and run it.
Returns an execution time in microseconds (one millionth (0.000001 or 1/1,000,000) of a second).
Example: this should take about 4 seconds, because we repeat it 2 times:
echo benchmark (function(){
sleep(1);
sleep(1);
}, 2);
How to make PHP errors/warning to log/display
"Named parameters" in PHP. There is no such thing, but we can "simulate" it with arrays.
In Python we can do:
def info(x = 1, y = 2, z = 3):
and then call it like this:
info(x = 100)
We can't do that in PHP, but we can simply pass an array with key => value pairs.
This is a working code - https://3v4l.org/Yj8vT
See var-dump-str.php
var_dump returning a string, in case we need it, for example to log it to a file, example:
error_log("Something something: ", var_dump_str($someArray));
