php di - PHP-DI - Differences between Factories and Objects -


php-di allows methods define injections, including factories , objects: http://php-di.org/doc/php-definitions.html.

factories:

testclass::class => function () {    return new testclass('param'); }

the testclass instance created lazily, when needed.

objects:

testclass::class => di\object()->constructor('param')

if use objects, instance created lazily?

if yes, what's difference between factories , objects?

php-di author here, seems there confusion (given question , how wrong other answer is). have improved documentation, clear things up: ec8120ee.

to answer questions:

if use objects, instance created lazily?

yes, definitions resolved lazily, object() too.

if yes, what's difference between factories , objects?

just syntax. in cases it's more practical write closure, in other cases may want avoid boilerplate using object().

it's syntax preference honestly.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
