Question

I’m very new to php and I’m trying to concatenate three strings. And this works, if I do so:

echo Test::getBaseUrl() , '/' , $append_url;

But this happens inside the method and I wish to return this to the callee, but when I add return instead of echo like this:

return Test::getBaseUrl() , '/' , $append_url;

I get an error like this :

PHP Parse error:  syntax error, unexpected ',' in /home/ubuntu/Test.php on line 31

Where I’m making the mistake?

Answer 1

echo is a language construct and it supports a special syntax, that allows to chain several echo-“actions”. This means

echo $a, $b;

is in fact

echo $a; echo $b;

(not really, it’s a little bit different, but thats not important)

What you are really looking for is the concatenation

echo $a . $b;

which (because this is a regular operator) works with everything, that can handle a string

return $a . $b;
