And i want to find "kse 100 kse 30 kmi 30" which is located at key number 23
I have tried in_array and other php array functions including preg_match but it dont find string in array. Is there a way to find string in my array. If yes then tell me

Answer 1

Well your "kse 100 kse 30 kmi 30" has a space " " before and after the string in your array.
string(136) " kse 100 kse 30 kmi 30 "
Is this the reason why you cannot find it? Because array_serach, in_array and other functions are looking for exact values.
Otherwise use strstr to compare if your string is inside your haystack but be careful. If you have similar content like "Hello" and "Hello World" in your array you might find the wrong entry to this is not really a good unique solution.
Anyway I am leaving a quick example:
$found = false;
foreach($myArray as $key => $value) {
if(strstr($value, "kse 100 kse 30 kmi 30") == true) {
$found = true;
break;
}
}
if($found == true) {
//Do something awesome!
} else {
//Do something not so awesome but still cool?
}

Answer 2

You should make use of array_search
Searches the array for a given value and returns the corresponding key if successful
So it must be like ..
echo $key = array_search('kse 100 kse 30 kmi 30', $yourarray); //"prints" 23
EDIT:
<?php
$array = [
0 => "colg - colgate palmolive (pakistan) ltd. ",
1 => "gatm - gul ahmed textile mills ltd. ",
2 => "atlh - atlas honda limited ",
3 => "ffbl - fauji fertilizer bin qasim",
4 => " - general news",
5 => "searl - the searl company ltd. ",
23 => " kse 100 kse 30 kmi 30 ",
24 => "26,730.82",
];
$array = array_map('trim',$array);
$searchText = 'kse 100 kse 30 kmi 30';
$searchText = trim($searchText);
echo $key = array_search($searchText, $array); //"prints" 23
Demo

Answer 3

Thanks For you help but i sort it out myself
for ($index = 10; $index < 35; $index++) {
if (substr_count(array[$index], 'kse 100') > 0) {
$IndexKey = $index;
}
}
Got The value of key where that variable is.

Answer 4

For the first one that matches:
$key = key(preg_grep('/kse 100/', $array));
