Question

Here is some code I have: (p just echos plus adds a newline)

foreach ($vanSteps as $k => $reqInfo) 
{
    p($k);
    if ('van' == $k) { p('The key is the van, continue'); continue; }//continue if we reached the part of the array where van is key
    //do stuff
}

and I’m getting this output:

0
The key is the van, continue
1
2
3
van
The key is the van, continue

Why does the if statement return true when the key is 0? This foreach loop handles logic that applies when the key == 0 (and any other key except if the key is ‘van’) and this messes up the logic because it’s return true when key is 0.

Any help?

Thank you.

Use === for this comparison. When PHP compares string and integer it first casts string to integer value and then does comparison.

See Comparison Operators in manual.
