PHP If Statement with Multiple Conditions

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'; 

you can use the boolean operator or: ||

if($var == 'abc' || $var == 'def' || $var == 'hij' || $var == 'klm' || $var == 'nop'){ echo "true"; } 

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"; } 

You can try this:

<?php echo (($var=='abc' || $var=='def' || $var=='hij' || $var=='klm' || $var=='nop') ? "true" : "false"); ?> 

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:

<?php echo match ($var) { 'abc','def','hij','klm' => 'true', }; ?> //echos 'true' as a string

PHP Manual

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

if(preg_match('abc', $val) || preg_match('def', $val) || ...) echo "true"
