How to get only matching values from an array in php. Example:
<?php
$a=array("1"=>"Hello","2"=>"World","3"=>"Check","4"=>"Here");
?>
from $a, if i have text like "He" or "ld" or "che" , How to show based on text get matching values and keys an array. Same like sql like query.
It's simple one liner.
You might be looking for preg_grep(). Using this function you can find possible REGEX from your given array.
$a=array("1"=>"Hello","2"=>"World","3"=>"Check","4"=>"Here");
$matches = preg_grep ("/^(.*)He(.*)$/", $a);
print_r($matches);
You can iterate the array and check every value if it contains your search string:
$searchStr = 'He';
$a=array("1"=>"Hello","2"=>"World","3"=>"Check","4"=>"Here");
foreach( $a as $currKey => $currValue ){
if (strpos($currValue, $searchStr) !== false) {
echo $currKey.' => '. $currValue.' ';
}
}
//prints 1 => Hello 4 => Here
You could create function for that, like this:
function find_in_list($a, $find) {
$result = array();
foreach ($a as $el) {
if (strpos($el, $find) !== false) {
$result[] = $el;
};
}
return $result;
}
Here is how you could call it:
print_r (find_in_list(array("Hello","World","Check","Here"), "el"));
output:
Array ( [0] => Hello )
