I Have the following Array and I would like to sort it based on the $term = "geo" in relation only to [result_title] ?

Array

(

    [0] => Array

        (

            [result_title] => Agathoklis Georgiou

            [result_subtext] => Active Employee

        )



    [1] => Array

        (

            [result_title] => Frixos Georgiou

            [result_subtext] => Active Employee

        )



    [2] => Array

        (

            [result_title] => George Ellinas

            [result_subtext] => Active Employee

        )



    [3] => Array

        (

            [result_title] => Georgi Georgiev

            [result_subtext] => Active Employee

        )



    [4] => Array

        (

            [result_title] => Charalambos Georgiou

            [result_subtext] => Former Employee

        )



    [5] => Array

        (

            [result_title] => Georgia Kantouna

            [result_subtext] => Former Employee

        )

)

The desired result should be:

Array

(

    [0] => Array

        (

            [result_title] => George Ellinas

            [result_subtext] => Active Employee



        )



    [1] => Array

        (

            [result_title] => Georgi Georgiev

            [result_subtext] => Active Employee





        )



    [2] => Array

        (

            [result_title] => Georgia Kantouna

            [result_subtext] => Former Employee

        )



    [3] => Array

        (

            [result_title] => Agathoklis Georgiou

            [result_subtext] => Active Employee

        )



    [4] => Array

        (

            [result_title] => Charalambos Georgiou

            [result_subtext] => Former Employee

        )



    [5] => Array

        (

            [result_title] => Frixos Georgiou

            [result_subtext] => Active Employee

        )

)

I have tried various methods such as:

usort($data, function($a, $b) use ($term) {

    $x = strpos($a["result_title"], $term) === false;

    $y = strpos($b["result_title"], $term) === false;

    if ($x && !$y) return 1;

    if ($y && !$x) return -1;



    // use this if you want to sort alphabetically after the keyword sort:

    return strcmp($a["result_title"], $b["result_title"]);



    // or if you only want to sort by whether or not the keyword was found:

    return 0;

});

and

usort($data, function ($a, $b) use ($term) {

    similar_text($term, $a["result_title"], $percentA);

    similar_text($term, $b["result_title"], $percentB);



    return $percentA === $percentB ? 0 : ($percentA > $percentB ? -1 : 1);

});

and

usort($data, function ($a, $b) use ($term) {

    $levA = levenshtein($term, $a["result_title"]);

    $levB = levenshtein($term, $b["result_title"]);



    return $levA === $levB ? 0 : ($levA > $levB ? 1 : -1);

});

and

usort($data, function($a, $b){ return $a["result_title"] - $b["result_title"]; }); 

and many more without any proper result. Or maybe I cannot understand the method to achieve my result?

I have also checked: php sorting an array based on a string and How to sort an array by similarity in relation to an inputted word. but the answers are giving me the result I'm looking for.

Here's a function that I think will do what you want. I've presumed you want to find the value of $term at the beginning of a word. This code extracts any keyword in the title which includes $term and then sorts based on whether the keyword was found, followed by the ordering of the keyword, or if they are both the same, on the title.

$term = 'geo';

usort($data, function ($a, $b) use ($term) {

    // find the term in first entry

    $t1 = preg_match("/^.*?b($termw*)b.*$/i", $a['result_title'], $matches) ? $matches[1] : '';

    // find the term in second entry

    $t2 = preg_match("/^.*?b($termw*)b.*$/i", $b['result_title'], $matches) ? $matches[1] : '';

    // check if the terms were found

    if ($t1 == '' && $t2 != '') return 1;

    if ($t1 != '' && $t2 == '') return -1;

    // found in both - if not the same, just sort on the keyword

    if ($t1 != $t2) return strcmp($t1, $t2);

    // found the same keyword, sort on the whole title

    return strcmp($a['result_title'], $b['result_title']);

});

Since the output is long (it is what you asked for) I've omitted it but I've made a demo on 3v4l.org.
