Go vs PHP Syntax Comparison

Data types PHP types:

bool
string
int //Integer 
float
array
object
NULL
resource

Go types:

string
bool
int int8  int16  int32  int64
uint uint8 uint16 uint32 uint64 uintptr
byte //uint8 
rune //int32
float32 float64
complex64 complex128
array
slices
map
struct

Variables Variable declarations

Go PHP
var i int $i = 0 // integer
var f float64 $f = 0.0 // float
var b bool $b = false // boolean
var s string $s = "" // string
var a [2]string $a = [] // array

Short variable declarations

Go PHP
i := 0 $i = 0 // integer
f := 0.0 $f = 0.0 // float
b := false $b = false // boolean
s := "" $s = "" // string
a := [1]string{"hello"} $a = [] // array

Type conversions Go

i := 42             // Signed integer
f := float64(i)     // Float
u := uint(f)        // Unsigned integer

PHP

$i = 1;
$f = (float) $i;    // 1.0
$b = (bool) $f      // true
$s = (string) $b    // "1"

Arrays Go

var a [2]string
a[0] = "Hello"
a[1] = "World"
// OR
a := [2]string{"hello", "world"}

PHP

$a = [
    "hello",
    "world"
];

Maps Go

m := map[string]string{
    "first_name": "Foo",
    "last_name": "Bar",
}

PHP

$m = [
    "first_name" => "Foo",
    "last_name" => "Bar"
];

Objects Go

package main
import "fmt"
type Person struct {
    Name string
    Address string
}
func main() {
    person := Person{"Foo bar", "Sydney, Australia"}
    fmt.Println(person.Name)
}

PHP

$person = new stdClass;
$person->Name = "Foo bar";
$person->Address = "Sydney, Australia";
echo $person->Name;
// Or using type casting
$person = (object) [
    'Name' => "Foo bar",
    'Address' => "Sydney, Australia"
];
echo $person->Name;

Functions Go

package main
import "fmt"
func fullname(firstName string, lastName string) (string) {
    return firstName + " " + lastName
}
func main() {
    name := fullname("Foo", "Bar")
    fmt.Println(name)
}

PHP

function fullname(string $firstName, string $lastName) : string {
    return $firstName . " " . $lastName;
}
$name = fullname("Foo", "Bar");
echo $name;

** Returning multiple results** Go

package main
import "fmt"
func swap(x, y string) (string, string) {
    return y, x
}
func main() {
    a, b := swap("hello", "world")
    fmt.Println(a, b)
}

PHP Returning an array to get multiple results

function swap(string $x, string $y): array {
    return [$y, $x];
}
[$a, $b] = swap('hello', 'world');
echo $a, $b;

** Control Statements** **If-Else** Go

package main
import (
    "fmt"
)
func compare(a int, b int) {
    if a > b {
        fmt.Println("a is bigger than b")
    } else {
        fmt.Println("a is NOT greater than b")
    }
}
func main() {
    compare(12, 10);
}

PHP

function compare(int $a, int $b) {
    if ($a > $b) {
        echo "a is bigger than b";
    } else {
        echo "a is NOT greater than b";
    }
}
compare(12, 10);

Switch Go

package main
import (
    "fmt"
    "runtime"
)
func main() {
    fmt.Print("Go runs on ")
     
    os := runtime.GOOS;
     
    switch os {
    case "darwin":
        fmt.Println("OS X.")
    case "linux":
        fmt.Println("Linux.")
    default:
        fmt.Printf("%s.\n", os)
    }
}

PHP

echo "PHP runs on ";
         
switch (PHP_OS) {
    case "darwin":
        echo "OS X.";
        break;
    case "linux":
        echo "Linux.";
        break;
    default:
        echo PHP_OS;
}

For loop Go

package main
import "fmt"
func main() {
    sum := 0
     
    for i := 0; i < 10; i++ {
        sum += i
    }
     
    fmt.Println(sum)
}

PHP

$sum = 0;
     
for ($i = 0; $i < 10; $i++) {
    $sum += $i;
}
echo $sum;

While loop Go

package main
import "fmt"
func main() {
    sum := 1
     
    for sum < 100 {
        sum += sum
    }
     
    fmt.Println(sum)
}

PHP

$sum = 1;
while ($sum < 100) {
    $sum += $sum;
}
echo $sum;

Foreach/Range Go

package main
import "fmt"
func main() {
    colours := []string{"Maroon", "Red", "Green", "Blue"}
     
    for index, colour := range colours {
        fmt.Printf("index: %d, colour: %s\n", index, colour)
    }
}

PHP

$colours = ["Maroon", "Red", "Green", "Blue"];
     
foreach($colours as $index => $colour) {
    echo "index: {$index}, colour: {$colour}\n";
}
