Question

I have problem echo’ing an array.

$test = 'one two three four';
$arr = explode(' ', $test);

echo '<br />+'.$arr[0].' +(>'.$arr[1].' <'.$arr[2].'';

It stops echoing at $arr[1], and I need this for a special query in mysql.

What I need to achieve is:

('+one +(>two <three)

Also, I would like to know how can I use “<” character from $arr[2] to ~. So in short, what I’m tring to achieve is:

('+one +(>two <three <four ... <infinite)

Answer 1

It doesn’t stop echoing, the browser just mistakes the < character for the start of a tag and acts accordingly.

If you want to display this output, you should call htmlspecialchars on it first. Otherwise (e.g. for the query) no special treatment is needed.

For your last question: you ‘d do something like

$test = 'one two three four five'; 
$arr = explode(' ', $test); 

$out = '+'.$arr[0].' +(>'.$arr[1].' <'.implode(' <', array_slice($arr, 2)).')';
echo htmlspecialchars($out); // only for echoing!
