[PHP] array_walk, or array_map, or foreach?

2006-10-20 Thread Dave M G 

PHP List,

I took a snippet of code right off the php.net site to use trim on all 
the elements of an array.


Theoretically, it should test if the element in an array is in turn 
another array, and break it down to the next level until it gets to a 
string it can use trim on.


This is the code:

public static function trimArray($array)
{
if (is_array($array))
{
array_walk($array, trimArray);
}
else
{
$array = trim($array);
}
return $array;
}

The function exists inside a static class called Utility where I keep 
all basic utility functions.


I don't know if it's the fact that it's in a static class that makes a 
difference, but I've tried the following variations on the line with 
array_walk() in it:


array_walk($array, Utlity::trimArray)

array_map(Utility::trimArray, $array)

array_map(trimArray, $array)

I've even tried accomplishing it with a foreach(), but no matter what I 
do, it doesn't work.


As it walks through the array, it seems to trim a copy of the element in 
the array, trim that, but leave the original array untouched.


What am I missing here?

 {
 array_walk($array, trimArray);

I'm too lazy too look, but usually when using a class method as a
handler for PHP callback functions you pass the method as follows:

array_walk( $array, array( 'ClassName', 'trimArray' ) );

Cheers,
Rob.

The callback function form array_walk expects to parameters:
  callback($key, $value);

But mysql_escape_string() only takes one.

As suggested earlier, use array_map() instead.

[PHP] array_walk

2002-06-06 Thread Chris Boget 

If you use array_walk with an associative array, the only
arguments that PHP automatically passes to the defined
array are the numerical/element keys.  Is there any way
you can force it to pass the associative keys?

For example, I have an array:

$bob = array( this = other );

Instead of passing this and other to your array, PHP 
passes 0 and other.  Is there any way I can make it
so that it passes this?

 Instead of passing this and other to your array, PHP
 passes 0 and other.  Is there any way I can make it
 so that it passes this?

[pulled from the manual directly]

Example 1. array_walk() example


$fruits = array (d=lemon, a=orange, b=banana, c=apple);


function test_alter ($item1, $key, $prefix) {

$item1 = $prefix: $item1;

}


function test_print ($item2, $key) {

echo $key. $item2br\n;

}

echo Before ...:\n;

array_walk ($fruits, 'test_print');

reset ($fruits);

array_walk ($fruits, 'test_alter', 'fruit');

echo ... and after:\n;

reset ($fruits);

array_walk ($fruits, 'test_print');




The printout of the program above will be:

Before ...:

d. lemon

a. orange

b. banana

c. apple

 and after:

d. fruit: lemon

a. fruit: orange

b. fruit: banana

c. fruit: apple

[PHP] array_walk() and class methods

2001-12-19 Thread php4 


i have class instance snagfu, of class snafu, with a method, fubar()

i have an array, $tarfu, and want to run it through array_walk(),

array_walk($tarfu, $snagfu-fubar) seems to be logical, if it's possible.

this obviously doesn't work.

How do i use a class method with array walk? or is it even possible? if
it's not possible, why not? seems to be as if it should be possible...

thanks.
