What is the best way to echo?

[kristen]

<?php echo $row['id']; ?>

OR

<? echo $row['id']; ?>

OR

<?=$row['id']; ?>

[trq]

The first is the only one guaranteed to be supported.

since there is a topic about echo...

 

i wanna ask... how to call all data from table

 

<? echo ......<what should i put here>.......; ?>

kristen: it depends on you, 3 of them will work, but the third once can save you some times.

for my own preference, i use the second one.

 

bubblebla: call data from table? i assume you mean from database's table..

not sure if my explanation is correct,

 

normally, when u make a query, you will have something like..

$row = mysql_fetch_array($query);

 

if you don't know the column name, you can echo the data like $row[0], $row[1]....

if you know the column name, you can echo the data like $row['id'], $row['name']...

if you use extract($row), you can straight away use it according to the column name, $id, $name...

 

cheers...

hi kevin..

 

yes.. table i mentioned is from the database..

 

thank you for your explanation.

[kristen]

Thanks, I've always been curious about this. I've seen it all three ways, but I normally use the 2nd.

Both the second and third options rely on the short_open_tag setting being turned on in your php.ini

 

I prefer the first - a couple extra characters is worth the fact that it will definitely work. It's also worth the fact that we get syntax highlighting on the forum with those tags.

I will second GingerRobot and thorpe.

 

The only time you should use the second or third option is if the script is designed for one server, and you know it will always have short_open_tag on.

 

If, for any reason, it gets turn off, anything using <? or <?= to begin parsing PHP will NOT be parsed. This can reveal sensitive variable information, vulnerabilities in your code, or simply allow someone to copy your source.

 

In my opinion, the guarantee that PHP will parse is worth the few extra characters.

I'll 3rd that. The second and third methods aren't reliable unless you personally manage the server that the script lies on.
