PHP output wrong way around

Question

Hopefully a simple one to replicate (assuming it's not my setup...)

I have the following in a PHP script:

echo('$userID:&emsp;' . var_dump($userID) . '<br>'); echo('$hashValidate:&emsp;' . var_dump($hashValidate) . '<br>');

The output is showing as:

bool(false) $userID:
bool(false) $hashValidate:

Shouldn't it be this way around though?

$userID: bool(false)
$hashValidate: bool(false)

No. var_dump() performs IMMEDIATE output, and has no return value. That means your code is running the same as if you had

var_dump($var) echo('$userID:&emsp;<br>');

You'd need this instead:

echo '$userID:' var_dump(...); echo '<br>';

I see, thanks for clarifying - and providing an alternative! I'll accept once the time limit has passed....

This code:

echo('$userID:&emsp;' . var_export($userID, true) . '<br>'); echo('$hashValidate:&emsp;' . var_export($hashValidate, true) . '<br>');

Lacks the information of MarcB's answer, but this method is arguably cleaner and at least matches more closely OP's expectations.
