How to make "LIKE" query work in MongoDB?
Use a regular expression:
db.streets.find( { street_name : /^Al/i } );or:
db.streets.find( { street_name : { $regex : '^Al', $options: 'i' } } );http://www.mongodb.org/display/DOCS/Advanced+Queries#AdvancedQueries-RegularExpressions
Turning this into PHP:
$regex = new MongoRegex("/^Al/i");$collection->find(array('street_name' => $regex));
See: http://www.mongodb.org/display/DOCS/SQL+to+Mongo+Mapping+Chart
Also, highly recommend just using the native mongodb connector from PHP instead of a wrapper. It's way faster than any wrapper.
