Difference between if and if endif

Question

Are there any differences between     if   value            and     if   value    endif

Both are the same   But  If you want to use PHP as your templating language in your view files the V of MVC  you can use this alternate syntax to distinguish between php code written to implement business-logic  Controller and Model parts of MVC  and gui-logic  Of course it is not mandatory and you can use what ever syntax you like   ZF uses that approach

Here s where you can find it in the official documentation  PHP  Alternative syntax for control structures

In the end you just don t want to be looking for the following line and then having to guess where it started    lt  php     gt    Technically and functionally they are the same

They are the same but the second one is great if you have MVC in your code and don t want to have a lot of echos in your code  For example  in my  phtml files  Zend Framework  I will write something like this    lt  php if  this- gt value     gt  Hello  lt  php elseif  this- gt asd     gt  Your name is   lt     this- gt name   gt   lt  php else    gt  You don t have a name   lt  php endif    gt

I think that it really depends on your personal coding style  If you re used to C    Javascript  etc   you might feel more comfortable using the    syntax  If you re used to Visual Basic  you might want to use the if   endif  syntax   I m not sure one can definitively say one is easier to read than the other - it s personal preference   I usually do something like this    lt  php if   foo      gt      lt p gt Foo  lt  p gt  lt  php   else     gt      lt p gt Bar  lt  p gt  lt  php       if-else   foo    gt    Whether that s easier to read than    lt  php if   foo     gt      lt p gt Foo  lt  p gt  lt  php else    gt      lt p gt Bar  lt  p gt  lt  php endif    gt    is a matter of opinion   I can see why some would feel the 2nd way is easier - but only if you haven t been programming in Javascript and C   all your life

I think this say it all      this alternative syntax is excellent   for improving legibility  for both PHP   and HTML   in situations where you   have a mix of them    http   ca3 php net manual en control-structures alternative-syntax php  When mixing HTML an PHP the alternative sytnax is much easier to read  In normal PHP documents the traditional syntax should be used

At our company  the preferred way for handling HTML is    lt   if  condition      gt     HTML content here  lt     else     gt     Other HTML content here  lt       gt    In the end  it really is a matter of choosing one and sticking with it

User · Answer

I would use the first option if at all possible  regardless of the new option   The syntax is standard and everyone knows it  It s also backwards compatible

I used to use curly brackets for  if  else  conditions  However  I found  if xxx   endif   is more semantic if the code is heavily wrapped and easier to read in any editors   Of course  lots editors are capable of recognise and highlight chunks of code when curly brackets are selected  Some also do well on  if xxx   endif  pair  eg  NetBeans   Personally  I would recommend  if xxx   endif   but for small condition check  eg  only one line of code   there are not much differences

I personally really hate the alternate syntax  One nice thing about the braces is that most IDEs  vim  etc all have bracket highlighting  In my text editor I can double click a brace and it will highlight the whole chunk so I can see where it ends and begins very easily   I don t know of a single editor that can highlight endif  endforeach  etc

User · Answer

I used to use the curly braces but now a days I prefer to use this short-hand alternative syntax because of code readability and accessibility

I think that it s particularly clearer when you re using a mix of ifs  fors and foreaches in view scripts    lt  php if    this- gt hasIterable      gt       lt h2 gt Iterable lt  h2 gt       lt ul gt       lt  php foreach    this- gt iterable as  key   gt   val     gt           lt  php for    i   0   i  lt    val   i        gt           lt li gt  lt  php echo  key   gt  lt  li gt           lt  php endfor    gt       lt  php endforeach    gt       lt  ul gt   lt  php elseif    this- gt hasScalar      gt       lt h2 gt Scalar lt  h2 gt       lt  php for    i   0   i  lt    this- gt scalar   i        gt       lt p gt Foo   Bar lt  p gt       lt  php endfor    gt   lt  php else    gt       lt h2 gt Other lt  h2 gt       lt  php if    this- gt otherVal     true      gt       lt p gt Spam lt  p gt       lt  php else    gt         lt p gt Eggs lt  p gt         lt  php endif    gt   lt  php endif    gt    as opposed to    lt  php if    this- gt hasIterable      gt       lt h2 gt Iterable lt  h2 gt       lt ul gt       lt  php foreach    this- gt iterable as  key   gt   val     gt           lt  php for    i   0   i  lt    val   i        gt           lt li gt  lt  php echo  key   gt  lt  li gt           lt  php     gt       lt  php     gt       lt  ul gt   lt  php   elseif    this- gt hasScalar      gt       lt h2 gt Scalar lt  h2 gt       lt  php for    i   0   i  lt    this- gt scalar   i        gt       lt p gt Foo   Bar lt  p gt       lt  php     gt   lt  php   else     gt       lt h2 gt Other lt  h2 gt       lt  php if    this- gt otherVal     true      gt       lt p gt Spam lt  p gt       lt  php   else     gt         lt p gt Eggs lt  p gt         lt  php     gt   lt  php     gt    This is especially useful for long control statements where you might not be able to see the top declaration from the bottom brace

Personally I prefer making it in two seperate sections  but within the same PHP like    lt  php      if  question1     variable 1   somehtml        else    variable 1   someotherhtml          if  question2             variable 2   somehtml2             else             variable 2   someotherhtml2                  etc   output  lt  lt  lt HERE htmlhtmlhtml variable1htmlhtmlhtml varianble2htmletcetcetc HERE  echo  output     gt    But maybe it is slower

There is no technical difference between the two syntaxes  The alternative syntax is not new  it was supported at least as far back as PHP 4  and perhaps even earlier   You might prefer the alternative form because it explicitly states which control structure is ending  endwhile  for example  can only terminate a while block  whereas if you encounter a brace  it could be closing anything   You might prefer the traditional syntax  though  if you use an editor that has special support for braces in other C-like syntaxes  Vim  for example  supports several keystrokes for navigating to matching braces and to the starts and ends of brace-delimited blocks  The alternative syntax would break that editor feature

User · Answer

It all depends  personally I prefer the traditional syntax with echos and plenty of indentations  since it s just so much easier to read    lt  php     if  something           doThis         else          echo   lt h1 gt Title lt  h1 gt               lt p gt This is a paragraph lt  p gt               lt p gt and another paragraph lt  p gt            gt    I agree alt syntax is cleaner with the different end clauses  but I really have a hard time dealing with them without help from text-editor highlighting  and I m just not used to seeing  condensed  code like this    lt  php if   this- gt isEnabledViewSwitcher        gt   lt p class  view-mode  gt       lt  php   modes    this- gt getModes      gt       lt  php if   modes  amp  amp  count   modes  gt 1     gt       lt label gt  lt  php echo  this- gt     View as     gt   lt  label gt       lt  php foreach   this- gt getModes   as   code  gt   label     gt           lt  php if  this- gt isModeActive   code      gt               lt strong title   lt  php echo   label   gt   class   lt  php echo strtolower   code     gt   gt  lt  php echo   label   gt  lt  strong gt  amp nbsp           lt  php else    gt               lt a href   lt  php echo  this- gt getModeUrl   code    gt   title   lt  php echo   label   gt   class   lt  php echo strtolower   code     gt   gt  lt  php echo   label   gt  lt  a gt  amp nbsp           lt  php endif    gt       lt  php endforeach    gt       lt  php endif    gt   lt  p gt   lt  php endif    gt

They are indeed both the same  functionally   But if the endif is getting too far from the correspondent if I think it s much better practice to give a referencing comment to it  Just so you can easily find where it was open  No matter what language it is   if  my horn is red or her umbrella is yellow                        let s pretend this is a lot of code in the middle      foreach  day in week            sing a different song day                           if my horn is red   That actually applies to any analogous  closing thing       Also  in general  editors deal better with curly brackets  in the sense they can point you to where it was open  But even that doesn t make the descriptive comments any less valid

I feel that none of the preexisting answers fully identify the answer here  so I m going to articulate my own perspective  Functionally  the two methods are the same  If the programer is familiar with other languages following C syntax  then they will likely feel more comfortable with the braces  or else if php is the first language that they re learning  they will feel more comfortable with the if endif syntax  since it seems closer to regular language   If you re a really serious programmer and need to get things done fast  then I do believe that the curly brace syntax is superior because it saves time typing  if   condition           body        compared to  if   condition           body   endif    This is especially true with other loops  say  a foreach where you would end up typing an extra 10 chars  With braces  you just need to type two characters  but for the keyword based syntax you have to type a whole extra keyword for every loop and conditional statement
