Question

I have the following as a result of a preg_match_all

Array ( [0] => Array ( [0] => $9.70 [1] => $10 [2] => $11.95 [3] => $0.49 [4] => $2.95 [5] => $2.95 [6] => $2.95 [7] => $2.95 [8] => $0.49 [9] => $9.70 ) ) 

I’m trying to print them all in a foreach loop but getting only first character.

Here’s what I’m trying:

$i = '0';

foreach ($matches[0] as $val) {
    echo $val[$i].'<br />';
    $i++;
}

Where am I going wrong?

Answer 1

In PHP foreach works a different way than you think. Let me explain this using the following code:

$matches = array('One', 'Two', 'Three');
foreach ($matches as $value) {
    // The following code is called once for every array item, and $value is set to that array item
    echo $value . '<br />';
}

This code gives the following output:

One
Two
Three

This happens because the foreach body is called once for every array item, and $value is set to the value of that array item. Using your code one only sees the first character, because PHP allows you to get a single character from a string using array syntax. Long story short, change your code to the following:

foreach ($matches[0] as $val) {
    echo $val . '<br />';
}
