Hi, I have a array looks like :
Array ( [0] => ‘C:MATLAB7worktext by PHP1business_2company/1business_2company_id118txt’
[1] => ‘C:MATLAB7worktext by PHP1business_2company/1business_2company_id119txt’
[2] => ‘C:MATLAB7worktext by PHP1business_2company/1business_2company_id11txt’
……
[10] => ‘C:MATLAB7worktext by PHP1business_2company/1business_2company_id8txt’ )

I want to only get the numeric string from each key of the array and get the output as:
Array ( [0] => 71212118 [1] =>71212119 [2] =>7121211 ……
[10] =>712128)

How to do this? ?

Thank You

@pcthugJul 14.2006 — This quick script I made should do the trick:[code=php]<?php
$array = array('C:MATLAB7worktext by PHP1business_2company/1business_2company_id118txt',
'C:MATLAB7worktext by PHP1business_2company/1business_2company_id119txt',
'C:MATLAB7worktext by PHP1business_2company/1business_2company_id11txt');

print_r($array);

// removes any characters that are not decimals
function onlyDecimals($str) {
$str = ereg_replace("[^0-9]", "", $str);
return $str;
}

print_r(array_map('onlyDecimals', $array));
?>[/code]Should output:Array
(
[0] =&gt; C:MATLAB7worktext by PHP1business_2company/1business_2company_id118txt
[1] =&gt; C:MATLAB7worktext by PHP1business_2company/1business_2company_id119txt
[2] =&gt; C:MATLAB7worktext by PHP1business_2company/1business_2company_id11txt
)
Array
(
[0] =&gt; 71212118
[1] =&gt; 71212119
[2] =&gt; 7121211
)
