Array Loop - get the first value into a foreach loop

Question

I have an array, and I want to get the first value into a foreach loop. then send that value to a function.

• This does not work

  foreach ($frequency as $i) {        
     showphp_AlexVortaro (getphp_AlexVortaro ($frequency[$i]));
     showphp_Smartfm(getphp_Smartfm($frequency[$i]));        
  }
  

Answer 1

$i is the value of your array in the foreach loop. Instead of sending $frequency[$i] you must use '$i'.

If you want to fetch the keys use the following construction:

foreach ($array as $key => $value) 
{
 // Do something
}

Answer 2

I think you mean to use the current 'exposed' offset as your functions' arguments:

foreach($frequency as $i) {        
   showphp_AlexVortaro (getphp_AlexVortaro($i));
   showphp_Smartfm(getphp_Smartfm($i));        
}

or:

for($i=0; $i<count($frequencies); $i++) {        
   showphp_AlexVortaro(getphp_AlexVortaro($frequencies[$i]));
   showphp_Smartfm($frequencies[$i]);        
}

Answer 3

The current(); function would return the first value;

echo current($array);
