PHP String or Character Replacement (preg_replace)
Sometimes you want to run multiple replacements on a string of text or an array. This method uses matching arrays for patterns and replacements to make it easy to see what is being swapped for what.
<?php
$aPatterns = array(
0 => '/"/', // look for this
);
$aReplacements = array(
0 => '', // replace with this
);
$sSafeName = preg_replace($aPatterns, $aReplacements, $sStringOfTextNeedingCleaning); //could also use $aArrayOfTextNeedingCleaning
?>Here is an example of what you get
<?php
$aPatterns = array(
0 => '/"/', // look for this
1 => '/help/',
2 => '/now/',
3 => '/!/',
);
$aReplacements = array(
0 => '', // replace with this
1 => 'money',
2 => 'now',
3 => '.',
);
$sStringOfTextNeedingCleaning = 'I need "some" help now!';
$sSafeName = preg_replace($aPatterns, $aReplacements, $sStringOfTextNeedingCleaning); //could also use $aArrayOfTextNeedingCleaning
echo $sStringOfTextNeedingCleaning;
echo $sSafeName;
//would output
// I need "some" help now!
// I need some money please.
