in_array help

[dink87522]

My code on one page is:

$_SESSION['q20'] = $countries[$rndWork]."D".$answer."D".$answer_result;

 

and on the next page is:

$q20 = $_SESSION['q20'];
for ($i = 0; $i < 3; $i = $i + 1){
$q20Split = array_slice(explode("D", $q20), i, 1);
$question20[i] = $q20Split; 
} ?>

 

however I get the following error which I have never seen before:

 

Warning: array_slice() expects parameter 2 to be long, string given in /home/public_html/geographytrainer.com/hsDis.php on line 31

$q20Split = array_slice(explode("D", $q20), $i, 1);

 

You forgot the $ before i.

Doh!

 

Thanks

$q20 = $_SESSION['q20'];
echo("q2a: $q20");
for ($i = 0; $i < 3; $i = $i + 1){
$q20Split = array_slice(explode("D", $q20), $i, 1);
$question20[i] = $q20Split; 
} 
echo("q0: ".$question20[0]);
echo("q1: ".$question20[1]);
echo("q2: ".$question20[2]);

 

q2a prints "GrenadaDSt. George'sD0"

q0, 1, 2 do nit print.

[dink87522]

I want it so that q0 prints "Grenada", q1 prints "St. George" and q2 prints "0". Currently they are all printing empty.

$question20[$i] = $q20Split; 

 

Once again you forgot the $ before the i.

[dink87522]

Hmm, still doesn't work.

 

q2a prints "GrenadaDSt. George'sD0"

while q0 prints "Array", q1 prints "Array" and q2 prints "Array"

 

Sorry I am only a beginner at PHP.

$q20 = $_SESSION['q20'];
$q20Split = explode("D", $q20);

Should do exactly what you want..
