Question

i am searching a text using in_array() function from the array which is fetching database value

$value is the array value.

How can i ignore case in this.

if(in_array($exp[$i],$value))

Answer 1

Use preg_grep() instead:

if( preg_grep( "/" . $exp [$i] . "/i" , $value ) )

(the i modifier added after the / makes it case insensitive)

However, since it seems it isn’t an array value, you shouldn’t be using in_array(), but stristr():

if ( stristr ($value, $exp [$i]))

(stristr() is the case insensitive version of strstr(), which finds the first occurrence of a string in another string)
