php + replace text inside an array resulting from query

问题

this is my approach, with no success anyways, but maybe it gives you an idea of what both my code and coding skills are like, as well as what I am trying to achieve.

 $data1 = mysql_query("SELECT * from `todolist` WHERE date > '$today' ") 
 or die(mysql_error());

 $data1b = str_replace("text-to-be-replaced", "replaced-text", $data1);

while($info1 = mysql_fetch_array( $data1b )) 
 {
Print "".$info1['thingtobedone'] . " with ".$info1['persontomeet'] . "<br />";
 }

Also, my approach is incorrect since what I would like to do is set a bunch of search and replace cases. Something like a list of "search for X and replace for Y" instead of only one replacement. Originally i thought of doing something like "replace A for B and rename array as STEP2", then get array called STEP2 and "search for C and replace it for D, and rename array as STEP3" but...i think this might not be the best way to do so =/

Any recommendations, pointers, corrections will be appreciated! Thanks in advance!

You can use the strtr() function in PHP to pass in a key => value pair of replacement rules:

$data = mysql_query('SELECT * FROM todolist WHERE date > CURDATE()') or die(mysql_error());

// Array of replacement rules. Keys of the array are strings to be replaced.
// Corresponding values of the keys are the replacement strings
$trans = array(
    'stringtoreplace1' => 'replacedstring1',
    'stringtoreplace2' => 'replacedstring2',
    'stringtoreplace3' => 'replacedstring3'
);

while($info = mysql_fetch_array($data)) 
{
    print strtr($info['thingtobedone'], $trans) . ' with ' . $info['persontomeet'] . '<br />';
}

Assuming thingtobedone is the column you want to make the replacements on.

Then when you call strtr($info['thingtobedone'], $trans), the function will take the string and replace all occurances of every key value in the $trans array with their corresponding values. It's a nice way to make many string-replacements all at once.
