在mongodb中搜索并将字符串替换为特殊字符

Question

I am using mongodb 2.4 with cakephp and as there is no direct way to search and replace string in array in mongo. I am looping through all records and using str_replace to replace string with special charcaters('/','+','-') etc. But it is not working if more than one special charcter appears in a string. Kindly help me out in using str_replace or another way to find and replace in mongo

Answer 1

One way could be using regex,

<?php
    echo preg_replace('/(\/|\+|-)+/i', ' ', $string);
?>
