Is there a way to clean up an if statement with many conditions?

you can use the switch function:

switch( $if )
{
    // same thing as if ( $condition == 'value' )
    case 'value':
          do this;
          break;
    case 'value2': 
    case 'value3':
         do that;
         break;
}

 

You can separate your conditions and have it broken down onto separate lines.

 

As my dad always said, "if it ain't broke don't fix it".

We'd have to see the actual code to know if there is a way to rewrite it using less conditions or a different structure.  If your goal is just to reduce the line length you can either

a) Use some temp variables to shorten the if -or-

b) Separate the conditions onto separate lines.

 

 

Eg, giving the original statement of:

if(condition1 && condition2 && (condition3 && condition4) || (condition5 && condition6) || (condition7 && condition8))

 

a)

$res1 = condition3 && condition4;
$res2 = condition5 && condition6;
$res3 = condition7 && condition8;

if(condition1 && condition2 && $res1 || $res2 || $res3)

 

 

b)

if(
condition1 
&& condition2 
&& (condition3 && condition4) 
|| (condition5 && condition6) 
|| (condition7 && condition8)
)
