Is that ok ?

function checkForMatch(string,array){
    var arrKeys = array.length;
    var match = false;
    var patt;
    for(i=0; i < arrKeys; i++ ){
        patt=new RegExp(" "+array[i]+" ");
        if(patt.test(string))
           match = true;
    }
    return match;
}

string = "She told me birds can fly and I agreed"; 

var array = new Array();
array[0] = "dog";  
array[1] = "cat";  
array[2] = "bird";  
array[3] = "birds can fly";


alert(checkForMatch(string, array));
