PHP Versions Question

[monkeybidz]

Will certain versions of PHP read this differently or not read at all?

 

$sample[mine]

and

$sample['mine']

[hostfreak]

No, not that I am aware of, but it is always best to use quotes (whether it be single or double), like in your second example.

How about line 1 of a php page, will this matter?

<?

vs.

<?php

You will even note in this forum code i posted the color difference. I feel it is read differently.

[monkeybidz]

Any takers?

This i pasted from the php.ini setting

 

; Allow the <? tag.  Otherwise, only <?php and <script> tags are recognized.

; NOTE: Using short tags should be avoided when developing applications or

; libraries that are meant for redistribution, or deployment on PHP

; servers which are not under your control, because short tags may not

; be supported on the target server. For portable, redistributable code,

; be sure not to use short tags.

short_open_tag = on

 

If it is set on <? and <?php will work, but <? is not recommended read the quote above.

The difference between <? and <?php is a configuration option (short_open_tag), best to use the long one as it can confuse the paser seeing as xml also using <? as its opening tag.

 

The difference between $arr[var] and $arr['var'] is the first one is invalid syntax, no matter what version your using it will produce a notice. Once again, notices can be turned off within the php.ini but its best to use the correct syntax in the first place.
