Question

I’m using preg_grep to make database queries per section, per example my database fields have footer_SOMETHING, footer_left, footer_middle and footer_right.

So my question is, having this:

preg_grep('/footer_left.*/', $colunas)

all my footer_left_** are included in my queries, but how do I do it to just return footer_ excluding left, middle or right?

example

footer_color

footer_left_border

footer_middle_width

footer_right_height

I just want to have

footer_color

Thanks in advance,

Pluda

If you want just footer_color and similar entries returned, then you can use a negative assertion to exclude left,right,middle with:

 preg_grep('/footer_(?!left|right|middle).*/', $colunas)
