The string I have used to looking for is below
<!-- PART -->
And it was easy, I just do
preg_replace('/<!-- PART -->/', $value);
But now I realise I need a new attribute to be added in the string (ID)
<!-- PART ID="zoneA" -->
So is it a way I can search for star with <!-- PART and end with --> and also if its possible to read the ID attribute value as well.
if (preg_match_all('/<!--[\w\s]+ID="(\w+)"\s?-->/', $text, $matches)){
echo $matches[1][0];//id
}
You can use the same pattern for preg_replace:
preg_replace('/<!--[\w\s]+ID="(\w+)"\s?-->/', $value, $text);
Do both together:
$pattern = '/<!--[\w\s]+ID="(\w+)"\s?-->/';
if (preg_match_all($pattern, $text, $matches)){
$id = $matches[1][0];
preg_replace($pattern, $value, $text);
}
print_r($matches) to see the structure of the array. In this case your ids should be $matches[1][0], $matches[1][1], $matches[1][2], etc. The number 1 in the first key indicates that you want what is in the parenthesis of the pattern as opposed to 0 which matches the whole expression.try this
if( preg_match_all("/<!--[\w\s]+ID="(\w+)"\s?-->/",$text,$err_program)) {
print_r($err_program);
preg_replace("/<!--[\w\s]+ID="(\w+)"\s?-->/",$value,$text)
}
