PHP get first few charactors and remove from string
<p>Does anyone know how to remove the first few characters from a string and remove them in PHP.</p>

<p>Like in the string "str_filename" I need to remove the "str_" and save the "filename".</p>

<p>But it has to remove as many charactors as it takes to get to the "_".</p>

<p>In other words, i need to remove all the characters up until and including the first "_" in the string.</p>
