Grep

Hi,

I have a file contents in a file.

$data=file('myfile.txt');

From this I have to grep for the strings between "Results" and "seconds".

Use file_get_contents to load the file into a string. Then use preg_match to search in it, using perl regex syntax.

Here you go.

<?php
foreach(file('somefile.txt') as $sLine)
{
    echo (1 === preg_match('~(?<=Results)(.+?)(?=seconds)~', $sLine, $aMatch)) ? $aMatch[0] : '' ;
}
?>

Hi,

Thanks for the reply.

Can you please tell me how to select only last value i.e 72 from this string
<b>1</b> - <b>10</b> of about <b>72</b>

You could use a regular expression to look for a <b> encapsulated number. Here's an example which takes comma-separated thousands into effect and gives an integer result.

$string = '<b>1</b> - <b>10</b> of about <b>72</b>';
$total  = 0;
if (preg_match('#<b>([\d,]+)</b>$#', $string, $match))
{
    $total = (int) str_replace(',', '', $match[1]);
}

echo 'There were about ', $total, ' matches.';
