I'd be pretty surprised if searching for things like:
PHP simple search input quotes
and things like that didn't turn up some solutions...
You might have to search in specific forums rather than a general
Google, but.
Here's one crude solution though:
<?php
$input = 'this is a "test expression" for search input';
//remove duplicate spaces:
$input = preg_replace('/\\s+/', ' ', $input);
//ignore leading/trailing blanks:
$input = trim($input);
$parts = explode('"', $input);
$terms = array();
$in_quotes = false;
foreach($parts as $expression){
$expression = trim($expression); //probably not needed...
if (strlen($expression)){
if (!$in_quotes){
//individual words:
$words = explode(' ', $expression);
$terms = array_merge($terms, $words);
}
else{
//in quotes, so this is a search term:
$terms[] = $expression;
}
}
$in_quotes = !$in_quotes;
}
var_dump($terms);
?>
Note that invalid input such as unbalanced quote marks will mess this
up big-time, probably...
But maybe that's just as well...
