array_key_exists contains string

Question

I am using array_key_exists on an associative array to detect if a key exists like this...

if (array_key_exists('Packaged price (£3.00)', $item))
{
echo 'The Key Exists';
}

This works fine, but I want to modify it so that it checks if the key has packaged in the name. So instead of checking just for 'Packaged price (£3.00)' it would also work for the following...

Packaged cost (£3.00)
Packaged price (£17.00)
Packaged Item

Is this possible?

array_key_exists will not work in that case it will perform exact match, for your requirement following may be used:

foreach($array as $key=>$val){
   $keyArray = explode(' ',$key);
   if(in_array('Packaged',$keyArray))
      echo "Key exists" ;
}

`for ($array as...`...? – Max Oct 20 '14 at 17:54

Don't need to explode and create another array. Just use any string function on that key to find out if the key contains the term `Packaged` – Hanky Panky Oct 20 '14 at 17:55

Simply loop through all the keys and check if any key contains the term Packaged

foreach($items as $key=>$value)
{
      if(stristr($key,'Packaged')!==FALSE)
         echo "Matching key is: $key";
}

Fiddle

$test = "Package sdsd";

echo preg_match("/(Package)+/",$test);

you can use simple regex , as an example above if the Package word occurs the string the result will be true
