[SOLVED] preg_replace() problems

[Kasuke_Akira]

Here's my code:

 

function cmc_convert ($str) {

    $simple_search = array(
 	'16',
	'12',
	'11',
	'10',
	'9',
	'8',
	'7',
	'6',
	'5',
	'4',
	'3',
	'2',
	'1',
	'W',
	'U',
	'B',
	'R',
	'G'
);

    $simple_replace = array(
 	'<img src=images/cmc_16.png>',
        '<img src=images/cmc_12.png>',
	'<img src=images/cmc_11.png>',
	'<img src=images/cmc_10.png>',
	'<img src=images/cmc_9.png>',
	'<img src=images/cmc_8.png>',
	'<img src=images/cmc_7.png>',
	'<img src=images/cmc_6.png>',
	'<img src=images/cmc_5.png>',
	'<img src=images/cmc_4.png>',
	'<img src=images/cmc_3.png>',
	'<img src=images/cmc_2.png>',
	'<img src=images/cmc_1.png>',
	'<img src=images/cmc_white.png>',
	'<img src=images/cmc_blue.png>',
	'<img src=images/cmc_black.png>',
	'<img src=images/cmc_red.png>',
	'<img src=images/cmc_green.png>'
);

    $str = preg_replace($simple_search, $simple_replace, $str);

    return $str;
} 

 

Basically....I don't know why it isn't working.  I realize it's probably in the $simple_search array, but I am not too good at string manipulation and was curious what I'm doing wrong.

 

If you know what I'm doing wrong and how to fix it, if you do fix it, can you explain to me why?  So I understand what's going on.  Thanks.

preg patterns need a starting and ending delimiter.  Look at the following example from the manual:

 

$string = 'The quick brown fox jumped over the lazy dog.';
$patterns[0] = '/quick/';
$patterns[1] = '/brown/';
$patterns[2] = '/fox/';
$replacements[2] = 'bear';
$replacements[1] = 'black';
$replacements[0] = 'slow';
echo preg_replace($patterns, $replacements, $string);

 

In this case, the delimiter is "/", and appears at the start and end of every search pattern.

I tried that and it didn't work.

Can you post the code you tried?

 

If you need to convince yourself that it works, try the sample code I posted.

OK, well I switched it from using my arrays, to setting it up like your example instead.  So that will do for now.  Thanks.  I'll just fiddle with my own code later....mebbe i can figure out wut I'm doing wrong.
