  $ MYVAR =阵列（）;
$ MYVAR ['VAR1'] ='你好';
$ MYVAR ['VAR2'] ='你好';
$ MYVAR ['VAR3'] ='你好';
$ MYVAR ['VAR4'] ='你好';
$ MYVAR ['VAR5'] ='你好';的print_r（memory_get_usage（））;

I have a question, what is more faster ...

1. I make many variables that contain all of my data, or
2. I make one array in one variable that contain all of my data and access it

解决方案

Just a try :)

Test 1

With 5 variables

$myvar1 = 'hello';
$myvar2 = 'hello';
$myvar3 = 'hello';
$myvar4 = 'hello';
$myvar4 = 'hello';

print_r(memory_get_usage());

Resut : 618600

Test 2

with 5 array keys

$myvar = array();
$myvar['var1'] = 'hello';
$myvar['var2'] = 'hello';
$myvar['var3'] = 'hello';
$myvar['var4'] = 'hello';
$myvar['var5'] = 'hello';

print_r(memory_get_usage());

Resut : 620256
