Hi,

I want to search a string and look for several words from an array and use a for each loop to go through the array. But I don’t know how to combine the code because I want the following code only to be activatet if there is no hit in the array, like !=.

Preciate some help. Thanks!

[COLOR=”Red”]$filter = array(“name1″,”name2″,”name3”);

$search = strstr($text, ??

for each ($filter as ??[/COLOR]

Following code to run if there is no match

Not sure if I understod your question correct, and I have never tried the strstr function, but what about moving the loop..

[code=php]$filter = array("name1","name2","name3");

foreach ($filter as $key => $name_to_check)
{
$search = strstr($text, $name_to_check);
}[/code]

You could also make $search an array to avoid the value to be overwritten!

Hope this is a help!

[code=php]<?php

$filter = array('name1', 'name2', 'name3');
$text = 'Is this your name2 or name1?';

$matches = array();
foreach ($filter as $item) {
if (strpos($text, $item) !== false) {
$matches[] = $item;
}
}

echo 'Searching: <b>' . $text . '</b><br /><br />';
if ($matches) {
echo count($matches) . ' MATCHES FOUND';
echo '<pre>' . print_r($matches, true) . '</pre>';
} else {
echo 'NO MATCHES FOUND';
}[/code]

$matches will return all the words from the array that are in $text.

It's perhaps a little bit hard to explain what I mean. I would like to do something like this....

if [COLOR="Red"]![/COLOR]($name1 == $not not in the string) {

Some code to be activated if there is no match

}

Or in plain english, do this if there is not any name from the array in the text... ?

@thraddashJan 14.2011 — How about this then...

[code=php]<?php

$filter = array('name1', 'name2', 'name3');
$text = 'Is this your?';

for ($i = 0; $i < count($filter); $i++) {
if (strpos($text, $filter[$i]) !== false) {break;}
}
if ($i >= count($filter)) {
echo 'Some code to be activated if there is no match';
}[/code]

The echo statement only happens if nothing in $filter matches $text.
