Compare a string and a php array and only show the matches - php

Question

I have a string that looks like this:
"illustration,drawing,printing"
I have an array that looks like this:
Array (
[0] => illustration
[1] => drawing
[2] => painting
[3] => ceramics
)
How can I compare the two and only display the terms that exist in both the string and array?
So in the above example, I would want to output something that looks like this:
SKILLS: illustration, drawing
Thank you!

Answer 1

use explode(), array_intersect() and implode()
<?php
$string = "illustration,drawing,printing";
$array = Array (
0 => 'illustration',
1 => 'drawing',
2 => 'painting',
3 => 'ceramics'
);
$stringArray = explode(',',$string);
$common = array_intersect($stringArray,$array);
echo "Skills :".implode(',',$common);

You can do something like this:
Function:
function functionName($string, $array){
$skills = '';
// Create a temp array from your string breaking appart from the commas
$temparr = explode(",", $string);
// Iterate through each of the words now
foreach($temparr as $str){
// Check to see if our current string is in the array provided
if(in_array($str, $array)){
// If it is, then add it to the string "skills"
$skills .= "${str}, ";
}
}
// Cut the last space and comma off the end of the str.
$skills = substr($skills, 0, strlen($skills) - 2);
// Return our results
return 'SKILLS: '.$skills;
}
Usage:
$string = "illustration,drawing,printing";
$array = Array (
0 => "illustration",
1 => "drawing",
2 => "painting",
3 => "ceramics"
);
// Just input our string and the array we want to search through
echo(functionName($string, $array));

Answer 3

You could replace the comma , and join the string words on OR | and grep for them. This will match the word anywhere in each array element:
$result = preg_grep("/".str_replace(",", "|", $string)."/", $array);
If you want exact matches only then: "/^(".str_replace(",", "|", $string).")$/"

Answer 4

Firstly convert that string into array.
use array_intersect();
$str = "illustration,drawing,printing";
$ar1 = explode(",",$str);
print_r ($ar1);
$ar2 = Array ("illustration","drawing","painting","ceramics");
echo "<br>";
print_r ($ar2);
$result = array_intersect($ar1, $ar2);
echo "Skills :".implode(',',$result);
OUTPUT:
Array (
[0] => illustration
[1] => drawing
[2] => printing
)
Array (
[0] => illustration
[1] => drawing
[2] => painting
[3] => ceramics
)
SKILLS: illustration, drawing
