If you don't get that data from an SQL query, you can sort that using usort
and stripos
; something like this should do :
$arr = array(
"Babyfood, plums, bananas and rice, strained",
"Bananas, dehydrated, or banana powder",
"Bananas, raw",
"Bread, banana, prepared from recipe, made with margarine",
"CAMPBELL Soup Company, V8 SPLASH Juice Drinks, Strawberry Banana",
"CAMPBELL Soup Company, V8 SPLASH Smoothies, Strawberry Banana",
"CAMPBELL Soup Company, V8 V. FUSION Juices, Strawberry Banana",
);
function compare_position($a, $b) {
return stripos($a, 'banana') - stripos($b, 'banana');
}
usort($arr, 'compare_position');
var_dump($arr);
i.e. you are here sorting with you own defined function, that compares the position (case-insentive) of "Banana" in the two strings it receives as parameters.
And you'll get this kind of output for your array, once sorted :
$ /usr/local/php-5.3/bin/php temp.php
array(7) {
[0]=>
string(37) "Bananas, dehydrated, or banana powder"
[1]=>
string(12) "Bananas, raw"
[2]=>
string(56) "Bread, banana, prepared from recipe, made with margarine"
[3]=>
string(43) "Babyfood, plums, bananas and rice, strained"
[4]=>
string(61) "CAMPBELL Soup Company, V8 SPLASH Smoothies, Strawberry Banana"
[5]=>
string(61) "CAMPBELL Soup Company, V8 V. FUSION Juices, Strawberry Banana"
[6]=>
string(64) "CAMPBELL Soup Company, V8 SPLASH Juice Drinks, Strawberry Banana"
}
Of course, if you get that data from an SQL query, it might be easier to do some additionnal calculations on the SQL side...
