Is there a way to....

[Anon]

I currently have code that does this:

if($variable == 'string1' || $variable == 'string2' || $variable == 'string3')

except it compares $variable to about 30 strings.

is there a function in PHP that makes this more elegant? in MySQL, i can do this:

$variable in('string1',string2', etc.....)

is there a similar fxn in PHP? i also thought about plugging all the strings into an array and running "in_array".

What would you all recommend?

you can write somthing like this :
$string=$string_1.$string_2.$string_3.... etc. and then use string function like strpos, or substr_count

I don't think there is a function to do this, but I would use arrays and loops:

<?
$flag = false;

your var

$variable = "";

your strings

$test_array = array('string1','string2');

foreach($test_array as $v){
if($varible == $v)
$flag = true;
}

if(!$flag){
// your code here
}

Or something like that...

Hope that helps.

BIG NOTE: smaller statements are NOT always faster. ie: don't go for smaller notation just because you are 'lazy', go for the notation that is easiest to maintain with the highest performance.

http://www.php.net/manual/en/function.in-array.php

if (in_array("hello", array('hello','goodbye','farewell')))
{
echo 'found it';
}

or switch:

switch('hello')
{
case 'hello':
case 'goodbye':
case 'farewell':
echo 'found it';
break;
default:
echo 'not found';
}
