Search some text in PHP array - php

Question

How can I search a word in a PHP array?
I try in_array, but it find just exactly the same values.
<?php
$namesArray = array('Peter', 'Joe', 'Glenn', 'Cleveland');
if (in_array('Peter Parker', $namesArray)) {echo "There is.";}
else {echo "There is not.";}
I want this instance to return true. How can I do it? Is there any function?

Answer 1

I have to say I like the simplicity of Gre_gor's answer, but for a more dynamic method you can also use array_filter():
function my_array_search($array, $needle){
$matches = array_filter($array, function ($haystack) use ($needle){
// return stripos($needle, $haystack) !== false; make the function case insensitive
return strpos($needle, $haystack) !== false;
});
return empty($matches) ? false : $matches;
}
$namesArray = ['Peter', 'Glenn', 'Meg', 'Griffin'];
Examples:
if(my_array_search($namesArray, 'Glenn Quagmire')){
echo 'There is'; // Glenn
} else {
echo 'There is not';
}
// optionally:
if(($retval = my_array_search($namesArray, 'Peter Griffin'))){
echo 'There is';
print_r($retval); // Peter, Griffin.
} else {
echo 'There is not';
}
Now $retval is optional, it captures an array of matching subjects. This works because if the $matches variable in my_array_search is empty, it returns false instead of an empty array.

Answer 2

Explode your string and then check, if there are any same strings in both arrays.
$namesArray = array('Peter', 'Joe', 'Glenn', 'Cleveland');
if (array_intersect(explode(' ', 'Peter Parker'), $namesArray))
echo "There is.";
else
echo "There is not.";

Answer 3

You can use Regular Expressions - preg_match ('i' means case insensitive) to check if array contains some words
for example:
$namesArray = array('Peter One', 'Other Peter', 'Glenn', 'Cleveland');
$check = false;
foreach($namesArray as $name)
{
if (preg_match("/.*peter.*/i", $name)) {
$check = true;
break;
}
}
if($check)
{
echo "There is.";
}
else {
echo "There is not.";
}
