php in_array doesn't output the result [closed]

Question

$testarray = array("Computer", 30.00, 123, 321");


if(in_array('Computer' , $testarray)){
  echo "yes!";
}else{
  echo "no!";
}

Guys, my in_array doesn't display yes output when in the array I have the computer value inside. Why is that so?

Answer 1

You have a syntax error in the first line, change it to

$testarray = array("Computer", 30.00, 123, "321");

or

$testarray = array("Computer", 30.00, 123, 321);

depending on if you whant the last value to be integer or string

Answer 2

You try this?

$testarray = array("Computer", 30.00, 123, 321);
if(in_array('Computer' , $testarray)){
   echo "yes!";
}else{
   echo "no!";
}

Just a syntax error. Enable PHP display_errors to see this error.

Answer 3

<?php
$testarray = array("Computer", 30.00, 123, 321);


if(in_array('Computer',$testarray )){
  echo "yes!";
}else{
  echo "no!";
}
?>

Your syntax is be wrong!!!
