Functionality:
This script uses ~80 URL requests and writes ~8000 arrays to a file (~50Mb-150Mb).
Performance:
The only goal is making this script as fast/efficient as possible (performance). There are alternative methods (such as this relevant question copied below), which I'm not so sure how to implement the alternative getSymbols method.
Would you be so kind and review my modified working code and kindly help me with the goal?
Alternative getSymbols():
public static function getSymbols()
return array_map(function($line) return str_getcsv($line, "t"); , file(__DIR__ . self::SYMBOLS_PATH));
Modified Code (Version II):
date_default_timezone_set("UTC");
ini_set('max_execution_time', 0);
ini_set('memory_limit', '-1');
set_time_limit(0);
// EquityRecords::allEquitiesSignleJSON(new EquityRecords());

Functionality:
This script uses ~80 URL requests and writes ~8000 arrays to a file (~50Mb-150Mb).
Performance:
The only goal is making this script as fast/efficient as possible (performance). There are alternative methods (such as this relevant question copied below), which I'm not so sure how to implement the alternative getSymbols method.
Would you be so kind and review my modified working code and kindly help me with the goal?
Alternative getSymbols():
public static function getSymbols()
return array_map(function($line) return str_getcsv($line, "t"); , file(__DIR__ . self::SYMBOLS_PATH));
Modified Code (Version II):
date_default_timezone_set("UTC");
ini_set('max_execution_time', 0);
ini_set('memory_limit', '-1');
set_time_limit(0);
// EquityRecords::allEquitiesSignleJSON(new EquityRecords());
class EquityRecords
const NUMBER_OF_STOCKS_PER_REQUEST = 100;
const NEW_LINE = "n";
/**
*
* @var a string of iextrading symbols
*/
const SYMBOLS_PATH = '/../../config/z-iextrading-symbs.md';
/**
*
* @var a string of our symbols json directory
*/
const SYMBOLS_DIR = "/../../data/equities/real-time-60sec/z-raw-equilibrium-estimation";
/**

*/
const TARGET_QUERY = "stock/market/batch?symbols=";
/**
*
* @var a string of iextrading base URL
*/
const BASE_URL = "https://api.iextrading.com/1.0/";
/**
*
* @var a string of iextrading end point
*/
const END_POINT = "&types=quote,chart&range=1m&last=10";
/**
*
* @var an integer for maximum number of stocks per URL on each call
*/

Could you let your IDE format the code consistently? That would free us from mentioning this boring topic in the code review.

@RolandIllig Hi Roland, Thanks for your comment, actually, I'm not a developer/programmer, never used an IDE before. Sometimes, I write on a paper or a text-editor such as Sublime. Not really know much about formatting. I surely understand, this is just a small project. Thank You!

I googled for "sublime format php" and found phpfmt, which looks promising. On that web page you just need to read the "Installation" and the "What does it do" sections. You can skip the long list of features if that looks frightening to you.

@Emma, Can you change the title to represent business requirement and not what you are doing. Ex: Creating Equity Dump?

Functionality:
This script uses ~80 URL requests and writes ~8000 arrays to a file (~50Mb-150Mb).
Performance:
The only goal is making this script as fast/efficient as possible (performance). There are alternative methods (such as this relevant question copied below), which I'm not so sure how to implement the alternative getSymbols method.
Would you be so kind and review my modified working code and kindly help me with the goal?
Alternative getSymbols():
public static function getSymbols()
return array_map(function($line) return str_getcsv($line, "t"); , file(__DIR__ . self::SYMBOLS_PATH));
Modified Code (Version II):
date_default_timezone_set("UTC");
ini_set('max_execution_time', 0);
ini_set('memory_limit', '-1');
set_time_limit(0);
// EquityRecords::allEquitiesSignleJSON(new EquityRecords());
class EquityRecords
const NUMBER_OF_STOCKS_PER_REQUEST = 100;
const NEW_LINE = "n";
/**
*
* @var a string of iextrading symbols
*/
const SYMBOLS_PATH = '/../../config/z-iextrading-symbs.md';
/**
*
* @var a string of our symbols json directory
*/
const SYMBOLS_DIR = "/../../data/equities/real-time-60sec/z-raw-equilibrium-estimation";
/**
*
* @var a string of target path and query
*/
const TARGET_QUERY = "stock/market/batch?symbols=";
/**
*
* @var a string of iextrading base URL
*/
const BASE_URL = "https://api.iextrading.com/1.0/";
/**
*
* @var a string of iextrading end point
*/
const END_POINT = "&types=quote,chart&range=1m&last=10";
/**
*
* @var an integer for maximum number of stocks per URL on each call
*/

Functionality:
This script uses ~80 URL requests and writes ~8000 arrays to a file (~50Mb-150Mb).
Performance:
The only goal is making this script as fast/efficient as possible (performance). There are alternative methods (such as this relevant question copied below), which I'm not so sure how to implement the alternative getSymbols method.
Would you be so kind and review my modified working code and kindly help me with the goal?
Alternative getSymbols():
public static function getSymbols()
return array_map(function($line) return str_getcsv($line, "t"); , file(__DIR__ . self::SYMBOLS_PATH));
Modified Code (Version II):
date_default_timezone_set("UTC");
ini_set('max_execution_time', 0);
ini_set('memory_limit', '-1');
set_time_limit(0);
// EquityRecords::allEquitiesSignleJSON(new EquityRecords());

const NEW_LINE = "n";

const SYMBOLS_DIR = "/../../data/equities/real-time-60sec/z-raw-equilibrium-estimation";
/**

Could you let your IDE format the code consistently? That would free us from mentioning this boring topic in the code review.

@RolandIllig Hi Roland, Thanks for your comment, actually, I'm not a developer/programmer, never used an IDE before. Sometimes, I write on a paper or a text-editor such as Sublime. Not really know much about formatting. I surely understand, this is just a small project. Thank You!

I googled for "sublime format php" and found phpfmt, which looks promising. On that web page you just need to read the "Installation" and the "What does it do" sections. You can skip the long list of features if that looks frightening to you.

@Emma, Can you change the title to represent business requirement and not what you are doing. Ex: Creating Equity Dump?
