php - How to find if $row contains certain characters -

having bit of coding issue, how can check see if value of $row['value'] contains characters, in case, if 'rename_file' contains filename has '128' in it. have doesn't seem echo when is.

$row = mysql_fetch_assoc($result); { while ($row = mysql_fetch_assoc($result))   {   echo $row['c_id'] . " " . $row['source_file'] . " " . $row['rename_file'] ." " . $row['p_id'];   if ($row['rename_file'] = '%128%') {   echo "<p> 128";   } else   echo "<br>";   } } 

many thanks. cp

use preg_match():

if(preg_match('/128/',$row['rename_file'])){     echo "<p> 128"; } else {     echo "<br>"; } 

or strpos():

if(strpos($row['rename_file'], '128') !== false){     echo "<p> 128"; } else {     echo "<br>"; }
