Is replace after < sign on echo but var_dump shows the correct length

Question

I have to generate a string using a given word, let's say "wheel" for full-text boolean mode search. But the second appearance of that word is replace after "<" sign when I'm trying to set the priority:

$word = 'wheel';
$x = '+(>' . $word . ' <' . $word . '*)';
echo $x;

The desired result should look like this:

+(>wheel <wheel*)

But instead the result is looking like this:

+(>wheel

But when I'm using var_dump I get the right length which is 17

I'm using PHP 5.6.40 Any idea why?

Have you tried `$x = '+(>' . $word . ' <(' . $word . '*))';` ? — Rakesh Jakhar, Oct 20 '19 at 09:25

If you are still using PHP 5 I strongly recommend to upgrade as soon as possible. This version is no longer supported. [Let Rasmus Lerdorf explain it to you](https://youtu.be/wCZ5TJCBWMg?t=2434) — Dharman, Oct 20 '19 at 11:26

Not sure why it's happening but if you add a space after < and single comma it's working fine. like this

$word = 'wheel';
$x = '+(>' . $word . ' < ' . $word . '*)';
echo $x;

Note: The extra space between < Symbol and ' Symbol

you didn't read the question @BlackXero, i need the < operator for full-text search, adding an extra space removes its purpose – Melody Oct 20 '19 at 09:04
