How I can use strpos in search by foreach in array - php

Question

The problem lies in the fact that I have to type the full name for the search phrase.
Maybe can I use strpos in this?
if ($filter && $searchOption && $searchPhrase && $sortField == "createDate" && $order == "asc") {
usort($caseList, function ($a, $b) {
/* #var $a CMCase */
/* #var $b CMCase */
$time1 = strtotime($a->createDate);
$time2 = strtotime($b->createDate);
return $time1 > $time2;
});
} else if ($filter && $searchOption == "search_customer" && $searchPhrase && $sortField && $order) {
$list = $caseList;
$caseList = array();
foreach ($list as $case) {
if ($case->customerName == $searchPhrase) {
$caseList[] = $case;
}
}
}

Answer 1

You can rewrite your code like this:
$result = array_filter($caseList, function($case) use ($searchPhrase){
return stripos($case->customerName, $searchPhrase) !== FALSE;
})
But you still need to be more concrete.
! I used stripos to case insensitive search. See the manual
P.S. Just try this instead of your code:
if ($searchOption == "search_customer" && $searchPhrase) use ($searchPhrase) {
$list = array_filter($caseList,function($case) {
return stripos($case->customerName, $searchPhrase) !== false;
});
}

This is my solution:
// Searching
{
if ($filter && $searchOption == "search_customer" && $searchPhrase && $sortField && $order) {
$list = array();
foreach ($caseList as $case) {
if (stripos($case->customerName,$searchPhrase)!== FALSE) {
$list[] = $case;
}
}
$caseList = $list;
} else if ($filter && $searchOption == "search_request" && $searchPhrase && $sortField && $order) {
$list = array();
foreach ($caseList as $case) {
if (stripos($case->identifier,$searchPhrase)!== FALSE) {
$list[] = $case;
}
}
$caseList = $list;
}
}
