strpos() nightmare

[The_Drummer]

This is very confusing.

I have developed some code to search through a string that is actually an element in an array, e.g. $my_array[1]

If I assign a value to my_array[1] in a simple php programme and do some pattern searches, I get the results I expect. Like this.

$my_array[1] = "HELLO THERE WORLD";
$pos = strpos(my_array[1], " THERE ");

pos will have the value of 5 for the beginning of the word " THERE ". Note the space at the front of THERE. I need to check for this complete string.

My aim is to change some code in an applicaiton.
The code is in a class, called say my_class()

The variable my_array[1] is assigned a value and I can print it out and see it, but my problem is that when I try and perform a test on the string like in the example above it fails to see the pattern. This is even though the string in my_array[1] does contain the pattern I am looking for and is in the right case.

Also, if I physically assign anything with the pattern I'm looking for to my_array[1] just before I check it with strpos() it finds the value.

Is there something I'm missing here?

Another thing I have just realised, that other string functions such as strtoupper() have no effect on the string. The following does not print a string with all characters in upper case.

echo("strtoupper($my_array[1])");

Is there a common issue here?

sorry, in my last example the query is not correct (blaming my book)
The following does work:
echo ("Upper string : ".strtoupper($my_array[1]).");

So this is not the problem, but something is preventing the search of the values in my_array[1].

Please help.
