multiple comparisons in if statement syntax help

[Darkmatter5]

Can I shorten this code

 

if($field=="survey_id_1" || $field=="survey_id_2" || $field=="survey_id_3)

 

to something like this?

 

if($field=="survey_id_1" || "survey_id_2" || "survey_id_3)

Can survey_id_1,survey_id_2,survey_id_3 etc can be kept in an array ?

As d.shankar suggests, you could do this:

<?php
if (in_array($field, array('survey_id_1', 'survey_id_2', 'survey_id_3'))
{

}
?>

 

In this case, though, that's not much of an improvement on length, unless you can build the comparative array dynamically in your code. Also, using your if clause is probably much faster than trying to use another function call for the comparison.
