pattern matching - PHP - How to find a specific number in a string? -

i run sneakers affiliate site , trying match imported product names existing sneaker models keyword. many formats around have use number sometimes, , numbers don't matched code use. tried different php str- functions none of them seem both numbers , strings.

 $models = array(     '106' => 'vans 106 vulcanized',     'alomar' => 'vans alomar',     'atwood' => 'vans atwood',     'authentic' => 'vans authentic',     // list goes on...  );   foreach ( $models $model_keyword => $model_name ) {       if ( stristr( $product_name, $model_keyword ) !== false ) {           return $model_name;       }   } 

as can see checking product name each of keywords , when it's found return model name. works every string contains letters or letters , numbers not numbers first item in array.

any ideas on how properly?

use strpos instead.

<?php  $models = array(     '106' => 'vans 106 vulcanized',     'alomar' => 'vans alomar',     'atwood' => 'vans atwood',     'authentic' => 'vans authentic'     // list goes on... );  foreach ($models $key => $name) {     if (strpos($name, (string)$key) !== false)         return $name; }
