删除引号内的报价regex php

Question

My String goes like this:

[...] 
if(round($pdf->GetY() >= 140)) { 
    $pdf->AddPage(); 
}
$pdf->Write(6,'Dutzler, Herbert - Letzter' Saibling'); 
$pdf->Ln(7); 
$pdf->SetFont('Helvetica','B',9); 
$pdf->SetTextColor(3 [...]

As you can see, FPDF cannot execute this command:

$pdf->Write(6,'Dutzler, Herbert - Letzter' Saibling'); 

because there is a quote inside quotes and it crashes.

Do you have any idea how I can remove or replace those inner quotes using regex? I have tried many different things, seems not to work properly :(

the code is coming from a huge database, here's a peek at the input code:

[LOOP] $pdf->Write(6,'[title]'); $pdf->Ln(7); $pdf->SetFont('Helvetica','B',9); [LOOP]

str_replace doesn't work properly if there are quotes inside [title] so it already fails at $str='[title]'. It's weird, I know.

Answer 1

Either escape the inside quote:

$pdf->Write(6,'Dutzler, Herbert - Letzter\' Saibling'); 

or use double quotes around the string instead of single quotes:

$pdf->Write(6,"Dutzler, Herbert - Letzter' Saibling"); 

No need for regexp, just write the code correctly in the first place.

Answer 2

Have you tried addslashes()? It should add slashes before quotes.
