[SOLVED] Searching within an array element

[eludlow]

I have an array in which each element is two numbers separated by a comma, eg 50,3

 

How would I go about checking whether a certain number matches the first half of the element?  Ie, I provide a variable $x and want to output each element that starts $x,5 or $x,49 etc etc

 

I tried using in_array but then realised that this only matched the element in its entirety.  I've a feeling it may need regular expressions?

 

Many thanks,

explode the array value into separate elements i.e

 

$x = array('5,10');
$parts = explode(",",$x[0]);

if($parts[0] == 5) {
	// the first number is 5
}

Perfect, thanks.

 

Solved a very similar problem I had earlier using explode() (after posting on the forum - see reg ex forum!) - should have thought of it myself

 

Many thanks.
