PHP strpos多个单词

Question

Basically I'm trying to see if the following is in a variable called $restext .

[TD="align: left"]'.$num.'[/TD] [TD="align: left"][/TD]

$num is a $_GET value which is a number.

From what I see it is failing when I use:

if(strpos($restext,'[TD="align: left"]'.$num.'[/TD] [TD="align: left"][/TD]')===false) {

}

because the string I am searching for is 2 words. There is a space after the first [/TD]

How can I search the the variable $restext for the string posted above?

Thanks!

Are you sure that you've taken into account the empty cell at the end?

$haystack = 'pastebin example';
$num = 1;
$needle = '[TD="align: left"]'.$num.'[/TD] [TD="align: left"][/TD]';
echo strpos($haystack, $needle) === false ? "Not found" : "Found"; //Found
$num = 4;
echo strpos($haystack, $needle) === false ? "Not found" : "Found"; //Not found

If you want to replace the value:

if(strpos($haystack, $needle) !== false) {
    $haystack = str_replace($needle, "New value", $haystack);
}
