Is there a PHP function to remove any/all key/value pairs that have a certain value from an array?

Question

I think questions like this are the reason why I don\'t like working with PHP. The manual is good, if you can find what you are looking for. After reading through the Array Func

Answer 1

Rebuild this "impossible" function, I'd suggest :
function pf_cleanarray($arraytoclean=false,$to_explode=false,$delimiter=false) { /* PortalPress.org 2011 [maintain this comment, please] - cleans up an array upto to NULL or makes an array with content; use with care and better not use on even length depending [associative] arrays


It looks terrible, I know, especially without indent on Stackoverflow. But when rebuilding, it can be a very useful, dynamic tool, using just the simplest functions, so you will be able to manipulate keys and values at will on a multi-array. The keyfunction is to delete empty values or make an array with explode, that's clean, but with a little trouble, it can be made into a function that eliminates the elements depending on key or value. - Igor M. -

Simple example:
$A[0][0][0][0][0][0]="A";
$A[1][0][0][0][0][0]="";
$A[2][0][0][0][0][0]="";
$A[0][0][0][0][0][1]="";
$A[1][0][0][0][0][1]="";
$A[2][0][0][0][0][1]="";
$A[0][0][0][0][0][2]="";
$A[1][0][0][0][0][2]="";
$A[2][0][0][0][0][2]="";
$A[0][0][0][0][0][3]="";
$A[1][0][0][0][0][3]="";
$A[2][0][0][0][0][3]="";
$A[0][0][0][0][0][4]="";
$A[1][0][0][0][0][4]="";
$A[2][0][0][0][0][4]="";
$A[0][0][0][0][0][5]="";
$A[1][0][0][0][0][5]="A";
$A[2][0][0][0][0][5]="";
The $A array: Array([0]=>Array([0]=>Array([0]=>Array([0]=>Array([0]=>Array([0]=>A[1]=>[2]=>[3]=>[4]=>[5]=>)))))
[1]=>Array([0]=>Array([0]=>Array([0]=>Array([0]=>Array([0]=>[1]=>[2]=>[3]=>[4]=>[5]=>A)))))
[2]=>Array([0]=>Array([0]=>Array([0]=>Array([0]=>Array([0]=>[1]=>[2]=>[3]=>[4]=>[5]=>))))))
Results in $A:
Array([0]=>Array([0]=>Array([0]=>Array([0]=>Array([0]=>Array([0]=>A)))))
[1]=>Array([0]=>Array([0]=>Array([0]=>Array([0]=>Array([0]=>A))))))
