Checking for multiple strpos values
I found the above answers incomplete and came up with my own function:
/**
* Multi string position detection. Returns the first position of $check found in
* $str or an associative array of all found positions if $getResults is enabled.
*
* Always returns boolean false if no matches are found.
*
* @param string $str The string to search
* @param string|array $check String literal / array of strings to check
* @param boolean $getResults Return associative array of positions?
* @return boolean|int|array False if no matches, int|array otherwise
*/
function multi_strpos($string, $check, $getResults = false)
{
$result = array();
$check = (array) $check;
foreach ($check as $s)
{
$pos = strpos($string, $s);
if ($pos !== false)
{
if ($getResults)
{
$result[$s] = $pos;
}
else
{
return $pos;
}
}
}
return empty($result) ? false : $result;
}
Usage:
$string = "A dog walks down the street with a mouse";
$check = 'dog';
$checks = ['dog', 'cat', 'mouse'];
#
# Quick first position found with single/multiple check
#
if (false !== $pos = multi_strpos($string, $check))
{
echo "$check was found at position $pos<br>";
}
if (false !== $pos = multi_strpos($string, $checks))
{
echo "A match was found at position $pos<br>";
}
#
# Multiple position found check
#
if (is_array($found = multi_strpos($string, $checks, true)))
{
foreach ($found as $s => $pos)
{
echo "$s was found at position $pos<br>";
}
}
try preg match for multiple
if (preg_match('/word|word2/i', $str))
strpos() with multiple needles?
I just used the OR statement (||)
<?php
if ((strpos($color,'1') || strpos($color,'2') || strpos($color,'3')) === true)
{
//do nothing
} else {
echo "checked";
}
?>
