Arrays and removing elements

[scottm]

Hello,

I'm stuck with a problem. I have a loop that goes through each element of an array. The elements are checked for validity and if the element is no longer valid I'd like to remove it from the array. But how? What function removes parts of an array and updates the key values? Do I have to write a separate function to carry out what I'd like to do? PHP3 only please!

try using array_filter() - it should do what you need.

Thanks for your answer...

but array_filter isn't a PHP function. At least not according to the doc section here or in the books I have.

array_slice comes close to what I need. But it works only with PHP4.I'm working still with PHP 3, or better said, I'm programming for downward compatibility.

I decided to create a second array with the values I wanted, instead of trying to delete the ones I didn't want out of the existing array.

That worked.

Thanks again anyway.

Scott
