Preg Match - if

[jaymc]

[quote]Here is my code

<?php
$string = "hi &?/\='\",%+ hi";
$patterns[0] = "/&/";
$patterns[1] = "/\?/";
$patterns[3] = "/\//";
$patterns[4] = "/\\\/";
$patterns[5] = "/=/";
$patterns[6] = "/'/";
$patterns[7] = "/\"/";
$patterns[8] = "/,/";
$patterns[9] = "/%/";
$patterns[10] = "/\+/";

if (preg_match($patterns, $string)) {echo "YES";} else {echo "NO";}
?>[/quote]

Just wondering why I get an error when running that

[i]Warning: preg_match() expects parameter 1 to be string, array given in /home/cff/public_html/testy.php on line 28
NO [/i]

Because the first parameter to preg_match should be a string and you're giving it an array.

IS their anyway I can use it with an array

If not, how do I set it out to check for each of those chars listed in the array

[Psycho]

Separate each item with the pipe character "|". That represents OR. So if any of those items are found it will return true:

[code]$patterns = "/&|\?|\/|\\\|=|'|\"|,|%|\+/";
if (preg_match($patterns, $string)) {echo "YES";} else {echo "NO";}[/code]

Worked great

Cheers

You can also run a foreach,a nd just use pregmatch on them one at a time, with a foreach statement
