Control Structures

PHP if; else if; else → Python if; elif; else

PHP

if ($x == 1){
	// ...
} else if ($x > 2){
	// ...
} else {
	// ...
}

// Or...
if ($x == 1):
	// ...
elseif ($x > 2):
	// ...
else:
	// ...
endif;

Python

if x == 1:
	# ...
elif x > 2:
	# ...
else:
	# ...

Ternary Operator

PHP

Syntax: $variable = (condition) ? ifConditionValue : elseValue;

$y = (empty($x)) ? '$x is empty' : '$x is not empty';

Python

Syntax: variable = ifConditionValue if condition else elseValue

y = "x is empty" if len(x) == 0 else "x is not empty"

PHP Function → Python Definition

Without Parameters

PHP

function foo(){
	return true;
}

foo();

Python

def foo():
	return True

foo()

With Parameters

PHP

function foo($param1=null, $param2=null, $param3=20){
	// do something...
}

foo(null, null, 40);

Python

def foo(param1=None, param2=None, param3=20):
	# do something...

foo(param3=40)

PHP Foreach → Python For

Simple Foreach Loops

PHP

foreach ($array as $value){
	echo $value."\n";
}

Python

for value in array:
	print value
del value # Optional

Array (List) Keys Only

PHP

foreach ($array as $key => $value){
	echo '$array[\''.$key."']"."\n";
}

Python

for key in range(len(array)):
	print "array["+str(key)+"]"
del key # Optional

Associative Arrays (Dictionaries)

PHP

foreach ($array as $key => $value){
	echo '$array[\''.$key."'] => $value\n";
}

Python

for key, value in enumerate(dictionary):
	print "dictionary[%s] => %s" % (key, value)
del key, value # Optional

Variables

Declaration

PHP

$var = ""; // All variables must start with a dollar sign ($)

Python

var = "" # Variables don't start with a dollar sign

Multiple Assignment

PHP

$var1 = $var2 = "";

Python

(var1, var2) = ""

Type Casting

PHP

$var = (str) 20;
$var = (int) true;
// ...

Python

var = str(20)
var = int(True)
# ...
