Great approach to remove all numbers from a string in PHP via regular expression. PRO level regular expression in PHP 😀 Instead of simple [0-9] or \d look:


 1
 2
 3
 4
 5
 6
 7
 8
 9
10
$words = preg_replace('/0/', '', $words ); // remove numbers
$words = preg_replace('/1/', '', $words ); // remove numbers
$words = preg_replace('/2/', '', $words ); // remove numbers
$words = preg_replace('/3/', '', $words ); // remove numbers
$words = preg_replace('/4/', '', $words ); // remove numbers
$words = preg_replace('/5/', '', $words ); // remove numbers
$words = preg_replace('/6/', '', $words ); // remove numbers
$words = preg_replace('/7/', '', $words ); // remove numbers
$words = preg_replace('/8/', '', $words ); // remove numbers
$words = preg_replace('/9/', '', $words ); // remove numbers

$file=$GLOBALS["LOGFILE"];
if(!is_file($file)){echo "<script>setTimeout(\"Procedure2$t()\",1000);</script>";return;}
$data=@file_get_contents($file);
if(strlen($data)<10){echo "<script>setTimeout(\"Procedure2$t()\",1000);</script>";return;}
