[PHP] Explain that function!

[Jackboy]

Well its very boring at the moment, and i can see a few web programmers are online

So i thought (to some peoples displeasure) that it would be fun to make a thread, letting people explain some functions etc.

And of course YES you can go to php.net, but some people find the site of it scary (although its a fit resource).

There are many functions that some people may know which others may have never heard of.

YOU MAY POST DEFINITIONS OFF OTHER SITES, BUT YOU MUST CREDIT THEM.


I will start off nice and easy

echo();

<?PHP
echo "Hello world!";
?>

Outputs all parameters.
echo() is not actually a function (it is a language construct), so you are not required to use parentheses with it. echo() (unlike some other language constructs) does not behave like a function, so it cannot always be used in the context of a function. Additionally, if you want to pass more than one parameter to echo(), the parameters must not be enclosed within parentheses.

TAKEN FROM PHP.NET

Should be echo 'hello' unless you need literal newlines etc.

<?php
echo "<a href=\"http://php.net\">Click here for all definitions, then we dont need this thread </a>";
?>

Wahey. Nicely done.

[Agnostic Bear]

<?php
echo "<a href=\"http://php.net\">Click here for all definitions, then we dont need this thread </a>";
?>

negative:

echo( '<a href="http://www.php.net/en/manual">Click</a>' );

() are my personal preference.

Yeah i like brackets too

Doing ""; just makes it confusing lol.

[Jackboy]

Woah sorry, u lot were at skool and i was bored.

I used to use () but i thought it was improper syntax or w/e..

was i wrong?

[L?KE]

I always thought brackets was proper syntax. They wouldn't be there for nothing.

I swear
echo "Hello";

is out dated compared to

echo("Hello");

Or am I just being an idiot
