you can use array_walk
:
function fcn(&$item) {
$item = substr(..do what you want here ...);
}
array_walk($matches, "fcn");
Question
I have a code that will produce array of strings.... now my problem is i need to substr each result of the array but i think array is not allowed to be used in substr...
please help:
CODE:
<?php
$file = 'upload/filter.txt';
$searchfor = $_POST['search'];
$btn = $_POST['button'];
$sum = 0;
if($btn == 'search') {
//prevents the browser from parsing this as HTML.
header('Content-Type: text/plain');
// get the file contents, assuming the file to be readable (and exist)
$contents = file_get_contents($file);
// escape special characters in the query
$pattern = preg_quote($searchfor, '/');
// finalise the regular expression, matching the whole line
$pattern = "/^.*$pattern.*\$/m";
// search, and store all matching occurences in $matches
if(preg_match_all($pattern, $contents, $matches)){
echo "Found matches:\n";
$result = implode("\n", $matches[0]);
echo $result;
}
else{
echo "No matches found";
}
}
?>
The $matches there is the array... i need to substr each result of the $matches

}
array_walk($matches, "fcn");

Proper use of array_walk
array_walk( $matches, substr(your area));
Array_map accepts several arrays
array_map(substr(your area), $matches1, $origarray2);
in your case
array_map(substr(your area), $matches);

To find a sub string in an array I use this function on a production site, works perfectly.
I convert the array to a collection because it's easier to manage.
public function substrInArray($substr, Array $array) {
$substr = strtolower($substr);
$array = collect($array); // convert array to collection
return $body_types->map(function ($array_item) {
return strtolower($array_item);
})->filter(function ($array_item) use ($substr) {
return substr_count($array_item, $substr);
})->keys()->first();
}
This will return the key from the first match, it's just an example you can tinker. Returns null
if nothing found.
