php - una - ¿Acortar números largos a K/M/B?

Question

He buscado esto mucho en Google, pero no puedo encontrar ninguna función útil en función de mis consultas.

Lo que quiero es:

100 -> 100
1000 -> 1,000
142840 -> 142,840

PERO

2023150 -> 2.023M ( i still want 3 additional numbers for more accuracy )
5430120215 -> 5.430B

Apreciaría totalmente cualquier función personalizada para elegir dinámicamente el límite si es posible.

¡Gracias!

Answer 1

Use number_format() :

if ($n < 1000000) {
    // Anything less than a million
    $n_format = number_format($n);
} else if ($n < 1000000000) {
    // Anything less than a billion
    $n_format = number_format($n / 1000000, 3) . ''M'';
} else {
    // At least a billion
    $n_format = number_format($n / 1000000000, 3) . ''B'';
}

Apreciaría totalmente cualquier función personalizada para elegir dinámicamente el límite si es posible.

Si "límite" se refiere a la cantidad de decimales (la precisión), eso es fácil:

function custom_number_format($n, $precision = 3) {
    if ($n < 1000000) {
        // Anything less than a million
        $n_format = number_format($n);
    } else if ($n < 1000000000) {
        // Anything less than a billion
        $n_format = number_format($n / 1000000, $precision) . ''M'';
    } else {
        // At least a billion
        $n_format = number_format($n / 1000000000, $precision) . ''B'';
    }

    return $n_format;
}

Answer 2

CakePHP tiene un Ayudante numérico con un método para toReadableSize . Deberías poder asimilarlo y pensar en algo por tu cuenta. En él, $this->precision es básicamente como number_format() , y __n es una función singular o plural.

Answer 3

Tomé la respuesta proporcionada por BoltClock y la ajusté un poco con la facilidad de configuración en mente.

// Shortens a number and attaches K, M, B, etc. accordingly
function number_shorten($number, $precision = 3, $divisors = null) {

    // Setup default $divisors if not provided
    if (!isset($divisors)) {
        $divisors = array(
            pow(1000, 0) => '''', // 1000^0 == 1
            pow(1000, 1) => ''K'', // Thousand
            pow(1000, 2) => ''M'', // Million
            pow(1000, 3) => ''B'', // Billion
            pow(1000, 4) => ''T'', // Trillion
            pow(1000, 5) => ''Qa'', // Quadrillion
            pow(1000, 6) => ''Qi'', // Quintillion
        );    
    }

    // Loop through each $divisor and find the
    // lowest amount that matches
    foreach ($divisors as $divisor => $shorthand) {
        if (abs($number) < ($divisor * 1000)) {
            // We found a match!
            break;
        }
    }

    // We found our match, or there were no matches.
    // Either way, use the last defined value for $divisor.
    return number_format($number / $divisor, $precision) . $shorthand;
}

<?php
// Converts a number into a short version, eg: 1000 -> 1k
// Based on: http://.com/a/4371114
function number_format_short( $n, $precision = 1 ) {
    if ($n < 900) {
        // 0 - 900
        $n_format = number_format($n, $precision);
        $suffix = '''';
    } else if ($n < 900000) {
        // 0.9k-850k
        $n_format = number_format($n / 1000, $precision);
        $suffix = ''K'';
    } else if ($n < 900000000) {
        // 0.9m-850m
        $n_format = number_format($n / 1000000, $precision);
        $suffix = ''M'';
    } else if ($n < 900000000000) {
        // 0.9b-850b
        $n_format = number_format($n / 1000000000, $precision);
        $suffix = ''B'';
    } else {
        // 0.9t+
        $n_format = number_format($n / 1000000000000, $precision);
        $suffix = ''T'';
    }
  // Remove unecessary zeroes after decimal. "1.0" -> "1"; "1.00" -> "1"
  // Intentionally does not affect partials, eg "1.50" -> "1.50"
    if ( $precision > 0 ) {
        $dotzero = ''.'' . str_repeat( ''0'', $precision );
        $n_format = str_replace( $dotzero, '''', $n_format );
    }
    return $n_format . $suffix;
}

Example Usage:
number_format_short(7201); // Output: 7.2k
Demo:
echo ''<table>'';
for($d = 0; $d < 16; $d++ ) {
    $n = intval("09" . str_repeat( "0", $d ));
    $n = $n / 10;

Answer 5

Puedes intentar esto

 function number_formation($number, $precision = 3) {
        if ($number < 1000000) {

            $formatted_number = number_format($number); /* less than a million */
        } else if ($number < 1000000000) {

            $formatted_number = number_format($number / 1000000, $precision) . ''M''; /* billion */
        } else {

            $formatted_number = number_format($number  / 1000000000, $precision) . ''B''; /* for billion */
        }

        return $formatted_number;
    }

Prueba esto

function custom_number_format($n, $precision = 1) {
        if ($n < 900) {
        // Default
         $n_format = number_format($n);
        } else if ($n < 900000) {
        // Thausand
        $n_format = number_format($n / 1000, $precision). ''K'';
        } else if ($n < 900000000) {
        // Million
        $n_format = number_format($n / 1000000, $precision). ''M'';
        } else if ($n < 900000000000) {
        // Billion
        $n_format = number_format($n / 1000000000, $precision). ''B'';
        } else {
        // Trillion
        $n_format = number_format($n / 1000000000000, $precision). ''T'';
    }
    return $n_format;
    }
