| Problem 1:
| We want to parse each element of an array contained in an object, but
| without leaving the scope of the object, and without use global vars.
| Our code contain an error, and you have to find the error, and the
solution.
| Sample code here :
array_walk, afaicr, is not aware of object instances and therefore would not
be able to find 'searchInLines'...causing your error.
a solution is to simply use array_search...which never leaves php native
code - array_walk does.
another good question to ask is, why do people not standardize their
nomanclature? why pascal 'Search' yet camel everything else including the
name of the class itself?
| class object
| {
| var $lines ;
| var $posFound ;
|
| function object()
| {
| $lines = array( ... ) ;
| ...
| }
|
| function Search($val)
| {
| /* Line with error : */
| array_walk($this->lines, 'searchInLines', $val );
|
| /* solution : */
| array_walk($this->lines, array( $this,'searchInLines'), $val );
| }
|
| function searchInLines(&line, $id, $valueToSearch)
| {
| if ( $line[$id] == $valueToSearch )
| $this->posFound = $id ;
| }
| }
