I have a variable$var.
I want echo "true" if $var is equal to any of the following values abc, def, hij, klm, or nop. Is there a way to do this with a single statement like &&??

An elegant way is building an array on the fly and using in_array():
if (in_array($var, array("abc", "def", "ghi")))
The switch statement is also an alternative:
switch ($var) {
case "abc":
case "def":
case "hij":
echo "yes";
break;
default:
echo "no";
}
if($var == "abc" || $var == "def" || ...)
{
echo "true";
}
Using "Or" instead of "And" would help here, i think

you can use in_array function of php
$array=array('abc', 'def', 'hij', 'klm', 'nop');
if (in_array($val,$array))
{
echo 'Value found';
}

Dont know, why you want to use &&. Theres an easier solution
echo in_array($var, array('abc', 'def', 'hij', 'klm', 'nop'))
? 'yes'
: 'no';
Comments
you can use the boolean operator or: ||
if($var == 'abc' || $var == 'def' || $var == 'hij' || $var == 'klm' || $var == 'nop'){
echo "true";
}

Sorry to resurrect this, but I stumbled across it & believe it adds value to the question.
In PHP 8.0.0^ you can now use the match expression like so:
echo match ($var) {
'abc','def','hij','klm' => 'true',
}
// echos 'true' as a string

You will also need
default => 'false' with your match cases, otherwise an exception UnhandledMatchError is thrown for any value not in the list.You can try this:
echo (($var=='abc' || $var=='def' || $var=='hij' || $var=='klm' || $var=='nop') ? "true" : "false");

I found this method worked for me:
$thisproduct = "my_product_id";
$array=array("$product1", "$product2", "$product3", "$product4");
if (in_array($thisproduct,$array)) {
echo "Product found";
}

in_array() was recommended 7 years earlier. This code-only answer adds no new value to the page.Try this piece of code:
$first = $string[0];
if($first == 'A' || $first == 'E' || $first == 'I' || $first == 'O' || $first == 'U') {
$v='starts with vowel';
}
else {
$v='does not start with vowel';
}

It will be good to use array and compare each value 1 by 1 in loop. Its give advantage to change the length of your tests array. Write a function taking 2 parameters, 1 is test array and other one is the value to be tested.
$test_array = ('test1','test2', 'test3','test4');
for($i = 0; $i < count($test_array); $i++){
if($test_value == $test_array[$i]){
$ret_val = true;
break;
}
else{
$ret_val = false;
}
}

I don't know if $var is a string and you want to find only those expressions but here it goes either way.
Try to use preg_match http://php.net/manual/en/function.preg-match.php
if(preg_match('abc', $val) || preg_match('def', $val) || ...)
echo "true"

Not to mention the missing delimiters in in the pattern.
