need help with function to find 6 digit numeric string

[jeffj]

I need to parse a string and attempt to find a substring in the string that contains 6 numeric digits. the first and last digit may or may not be preceded by a space.

 

I need to find the starting the ending positions of the 6 numeric digits to that I can extract the string and build an href containing the string and replace those 6 digits with a hyperlink.

 

can someone help me...

 

thanks in advance.

You could do a substr for any number and then count 5 characters after that number and put the result in a variable

thanks I was looking more for help along the line of a function someone may have already written, since end of string/string length would have to be computer first using  your idea to avoid run time errors.

Are the 6 numeric characters the same all the time?

 

if they are always the same characters you can use something like this.

if (stristr($string, "6numericCharacters") !== FALSE) {
      //whatever you wanted to do to the string that contains the 6 numbers
}

<pre>
<?php

$string = 'abc123def4567890...';
preg_match('/\d{6}/', $string, $matches, PREG_OFFSET_CAPTURE);
print_r($matches);

?>
