Faster string operations
<p>I realise that the users system is a factor in this but if I was working on extracting data from a string, which would be more efficient? PHP or JavaScript?</p>

<p>lets say I have <code>ch_123456789abc_wakkawakka</code> (returned from a mysql query), would it be better to explode out the <code>123456789abc</code> part in php or on the client side? Either way the first string will still be transmitted so this is not a question of a smaller response size. I'm just interested in which the faster engine would be.</p>
