Tnx to Dominic, who told me the following foolish bug:
You can use array_search
for searching for elements in arrays.
|
|
|
<?php
$array = array("first", "second", "third");
foreach ($array as $value)
echo "value in array: $value<br>";
echo "searching for element 'second':<br>";
if ($found = array_search("second", $array))
echo "FOUND!<br>";
else echo "<b>NOT FOUND!</b><br>";
?>
|
That's how you do it. And it works fine as long as you try to find an element somewhere in
the array, not the first element.

<?php
$array = array("first", "second", "third");
foreach ($array as $value)
echo "value in array: $value<br>";
echo "searching for element 'first':<br>";
if ($found = array_search("first", $array))
echo "FOUND!<br>";
else echo "<b>NOT FOUND! 'first' does not seem to be in the array, as it could not be found...</b><br>";
?>

But looking for the first element does not work.

Today (7.12.2005), a reader sent in the solution (thanks to phazei):

<?php
$array = array("first", "second", "third");
foreach ($array as $value)
echo "value in array: $value<br>";
echo "searching for element 'first':<br>";
if (FALSE !== array_search("first", $array))
{
echo "FOUND!<br>";
}
else echo "<b>NOT FOUND! 'first' does not seem to be in the array, as it could not be found...</b><br>";
?>

It shows again, that weak typing and internal typing produce the need for new operators such as '===' and '!==' ...
