PHP loop error (unexpected = expected ;)

[borisjake]

I'm getting this error:

Parse error: syntax error, unexpected '=', expecting ';' on line 27

Heres the code:

25     words = explode(" ", $sentence);
26
27     for ($i=0; $i<=$sentenceLength; $i++)
28     {
29            wordLength = strlen($words[$i]);
30            $isdoibroi = false;
31
32            if ($wordLength <5)
33            {
34                    isdoibroi = true;
35                    echo "DOI";
35            }
36     }

Its driving me crazy and I just know its probably just a stupid mistake...

[swift and shift]

you need to put $ in front of all your variables, not just the ones you feel like

Weird, still getting the same error:

 
27 for ($i=0; $i<=$sentenceLength; $i++)
28 {
29                 $wordLength = strlen($words[$i]);
30                 $isdoibroi = false;
31
32                 if ($wordLength <5)
33                 {
34                           $isdoibroi = true;
35                           echo "DOI";
36                 }
37 }

Did you remember the variable above your for statement?

Also you should use foreach to iterate arrays in PHP, its easier to read and is sometimes faster.

foreach($words as $i => $word){
    $wordLength = strlen($word);
    [...]
}

Optionally you can reference the variable, wich is pretty useful in many situations. But you can read all about that here:

Yeah that variable is fine now but still getting that error.

Tried to move { to the same line as the for statement?

Turns out I accidentally uploaded two versions under different names... Sorry to waste time it was an error I fixed then didn't upload the correct version.

Should this thread be closed?
