count occurrences of test in string php, not test123 or testabc

i used code:

$text = 'This is test22 is a test11 abc test mlk'
result= substr_count($text, 'test',0,0)

result = 3;

but my desired output = 1;

i just want to count the number of occurrences of the exact word test, not testaaa or test123

Thank you

>Solution :

A string check alone can’t do this. I would use a regex for this. Using word boundaries and preg_match this can be done with:

$text = 'This is test22 is a test11 abc test mlk';
preg_match('/\btest\b/', $text, $result);
echo count($result);

Alternatively preg_replace could be used which has a count feature built into it.

preg_replace('/\btest\b/', '', $text, -1, $count);
