If match some word in php
index.php
Example:
PHP
<?php
$data = "bangla";
if (strpos($data, 'bangla')!==false || strpos($data, 'english')!== false) {
echo "Found";
} else {
echo "Not Found";
}
?>
Output should be:
PHP Match Specific Word
Here is a function that can perform this operation without using regular expressions which could be slower. Instead of passing a single string for the task, pass an array like
index.php
Example:
PHP
<?php
// function
function strposMultiple($haystack, $needle, $offset = 0) {
if(is_string($needle))
return strpos($haystack, $needle, $offset);
else {
$min = false;
foreach($needle as $n) {
$pos = strpos($haystack, $n, $offset);
if($min === false || $pos < $min) {
$min = $pos;
}
}
return $min;
}
}
// PHP Code for Result
$data = 'bad';
if (strposMultiple($data, ['bad', 'naughty']) !== false) {
echo 'Matched';
} else {
echo 'Not Matched';
}
?>
Output should be:
If Match Some Word
For this, you will need Regular Expressions and the preg_match function. Something like:
index.php
Example:
PHP
<?php
$data = 'bad';
if(preg_match('(bad|naughty)', $data) === 1)
{
echo 'Yes';
} else {
echo 'No';
}
?>
Output should be:
If Multiple Word Match
(preg_match return 1 if there is a match in the string, 0 otherwise).
multiple str_pos calls
index.php
Example:
PHP
<?php
$data = 'bad';
if (strpos($data, 'bad')!==false or strpos($data, 'naughty')!== false) {
echo "Found";
} else {
echo "Not Found";
}
?>
