PHP IF with multiple days of the week

Is this possible?

$d=date("D");
...
else if ($d=='(Thu|Fri|Sat)') {

I can get a single day of the week working.

if ($d=='Wed') {

Thanks

$d == '(Thu|Fri|Sat)' will only match if $d matches that exact string.

You could:

  • Use a regular expression: preg_match('/^(Thu|Fri|Sat)$/', $d),
  • An array of values: in_array($d, array( 'Thu', 'Fri', 'Sat' )), or
  • Mulitple if statements: if($d == 'Thu' || $d == 'Fri' || $d == 'Sat');
  • Use a switch/case structure

No. For what you want, in_array() is the best choice.

if(in_array($d, array('Thu', 'Fri', 'Sat'))
  // do something if any case is true

If you want more control, switch and case are very handy and give you more control over different cases.

$d = date('D');

switch($d) {
  case 'Thu':
  case 'Fri':
  case 'Sat':
    // do something for Thu, Fri, or Sat
    break;

  case 'Mon':
    // do something only for Mon
  case 'Tue':
    // do something for Mon or Tue.
    break;
}

The first set of cases will apply the following code (up until break) if any or all of the conditions are met.

The second set will apply the code between cases Mon and Tue if Mon is true, and then continue to Tue if it is true.

switch and case can be very useful, especially here if you want real control.

Just use in_array()

if (in_array($d, array("Thu", "Fri", "Sat"))) {

}

Why can't you use or or ||?

else if ($d=='Thu' || $d=='Fri' || $d=='Sat') {

If you dont want to stick to simplicity then use preg_replace()[docs]

preg_match('^(Thu|Fri|Sat)$', $yourtext, $matches, PREG_OFFSET_CAPTURE);
if(count($matches)) {
    /// found
}

You could use the OR operator:

else if ($d=='Thu' || $d=='Fri' || $d=='Sat') {

Try

if(in_array($d, array('Thu', 'Fri', 'etc'))){
}

Or with ||

if($d == 'Thu' || $d == 'Fri' || etc)
